Brain games should give your dog something enjoyable and achievable to do.

They might sniff for food, work out how to open a simple puzzle, lick something suitable from a mat or investigate a cardboard box.

But enrichment is not automatically beneficial simply because it has been labelled a brain game.

A puzzle can be too difficult.

A snuffle mat can create frustration.

A food toy can encourage frantic biting.

A homemade activity can contain pieces your dog may swallow.

And a game one dog enjoys may lead to guarding or competition in a home with more than one pet.

I have worked with dogs professionally since 2011. One of the most common enrichment mistakes I see is the belief that a harder activity must provide greater mental stimulation.

It does not.

A dog repeatedly pawing, barking at or attacking a puzzle is not necessarily enjoying a satisfying challenge.

They may be confused, frustrated, worried or physically uncomfortable.

Some dogs will persist long after an activity has stopped being enjoyable because they can still smell food inside it.

That does not mean the difficulty is suitable.

Good enrichment should fit the individual dog.

It should take into account their age, confidence, health, chewing style, experience, and behaviour around food.

And it should be made easier or stopped when the dog is struggling.

This guide explains how to tell the difference between useful problem-solving and frustration, how to make brain games safer and what to do when an enrichment activity goes wrong.

What should safe enrichment look like?

Safe enrichment allows your dog to use natural behaviours in ways that suit them.

That may include:

sniffing
searching
licking
chewing
shredding suitable materials
exploring
problem-solving
making choices
learning simple skills

Dogs Trust’s enrichment guidance explains that enrichment can encourage natural behaviours, help prevent boredom and build confidence.

But enrichment should also be:

appropriate for your dog
easy enough to understand
physically safe
supervised where necessary
introduced gradually
free from competition
stopped before frustration
adjusted when your dog’s needs change

A safe brain game does not need to be difficult.

Scatter feeding several visible pieces of food may provide more useful enrichment than a complicated puzzle your dog cannot solve.

The aim is not to test your dog.

The aim is to give them a positive activity.

Persistence is not always enjoyment.

Dogs can be persistent.

If they can smell food inside a toy, they may continue scratching, biting, throwing, or shaking it, even when the activity causes frustration.

Owners may interpret this persistence as a sign of concentration.

Sometimes it is.

But continuing does not automatically mean your dog is enjoying the experience.

Look at how they are behaving.

A dog who is calmly working through a familiar puzzle may:

sniff carefully
pause
change approach
take food gently
return after a brief break
keep a relatively loose body
finish and settle afterwards

A frustrated dog may:

bark at the toy
bite it hard
throw it repeatedly
scrape at it with increasing force
whine
look repeatedly towards you
grab food roughly
pace around the activity
abandon it and return in a more frantic state
remain restless afterwards

The presence of food can keep a dog engaged even after the activity is no longer useful.

Do not wait for your dog to give up before helping them.

Why brain games become frustrating

The activity is too difficult

Food may be hidden too deeply.

A compartment may be difficult to move.

A frozen filling may be packed too tightly.

Your dog may not understand what action releases the food.

Your dog has not learnt the easier version

Many puzzle toys have several levels or stages.

Starting with every compartment closed may be too much.

Your dog needs to learn first that gentle interaction with the object releases food.

The toy keeps moving away

Rolling toys can slide under furniture or move across slippery flooring.

A dog may spend more time chasing the object than solving the puzzle.

The activity requires uncomfortable movement.

A senior dog or a dog with pain may struggle to bend, paw, twist or stand over a puzzle.

Their frustration may be physical rather than mental.

The reward is too difficult to reach

Your dog can smell or see food but cannot access it.

This can be particularly frustrating when food is trapped in corners or frozen beyond reach.

The environment is too busy.

Another dog, a child, household noise or people watching closely can add pressure.

Your dog is too excited to think.

A dog who has just returned from a highly stimulating walk may not be ready for a complicated puzzle.

They may need water, a quiet room and rest.

The dog is hungry

A very hungry dog may approach a food puzzle with more intensity.

Using the whole meal in a difficult toy can create unnecessary frustration.

The dog does not enjoy that type of activity

Not every dog enjoys puzzle boards, rolling toys or shredding boxes.

Your dog may prefer a calm scent search or an ordinary meal.

That is not a failure.

Signs your dog is enjoying the activity

A dog enjoying a suitable brain game may:

approach voluntarily
show relaxed curiosity
sniff calmly
work at a steady pace
pause without becoming distressed
try another simple approach
take food normally
move away and return
respond to you as usual
finish and settle afterwards

Body language varies between dogs.

Some dogs naturally work more energetically than others.

Compare your dog with their normal behaviour rather than expecting every dog to look identical.

Ask yourself:

Is my dog choosing to take part?
Can they pause?
Can they move away?
Is their body relatively loose?
Are they able to access regular rewards?
Do they seem settled afterwards?

When the answer is yes, the activity is probably at a manageable level.

Signs your dog is becoming frustrated

Frustration often builds.

Early signs may include:

looking repeatedly between you and the puzzle
stopping and staring at the toy
pawing more forcefully
whining
licking their lips
grabbing food roughly
trying the same unsuccessful movement repeatedly
walking away and immediately returning
becoming faster and less controlled

More obvious signs can include:

barking at the puzzle
biting the product
shaking it violently
throwing it around
scratching the floor
tearing pieces off
growling
redirecting biting towards a person or another pet
becoming unable to settle

Do not treat these signs as proof that your dog needs a harder challenge.

They usually mean you should make the activity easier, provide help or stop.

My guide Is Your Dog Hyperactive, Overstimulated, Bored or Overtired? explains why restless or frantic behaviour does not always mean a dog needs more activity.

Signs your dog may be worried

A dog may find the object itself frightening.

Watch for:

freezing
leaning away
approaching with a lowered body
repeatedly retreating
refusing food
turning their head away
excessive lip licking
yawning
pinning their ears back
tucking or lowering their tail
staring without approaching
leaving the room
hiding
barking from a distance

Possible causes include:

the toy moving unexpectedly
food hitting a metal surface
an object rolling towards the dog
a box collapsing
a person leaning over them
being filmed at close range
another dog approaching
unfamiliar materials or smells

Do not place the puzzle closer when your dog retreats.

Create more space.

My low-pressure enrichment guide for nervous and rescue dogs explains how to introduce simple activities without forcing participation.

How to make a brain game easier

You rarely need to abandon enrichment completely.

Often, a few simple changes are enough.

Show your dog where the food is

Let your dog watch you place it.

Leave some food visible.

Do not begin with everything concealed.

Open the compartments

Remove sliders, covers or balls.

Allow your dog to eat from the open puzzle first.

Use loose food

Do not tightly pack or freeze a food toy for a beginner.

Start with food that falls out easily.

Reduce the search area.

Hide food in one room rather than throughout the house.

Use one box instead of several.

Use fewer objects

A box containing paper, tubes, towels and smaller boxes may be overwhelming.

Begin with an empty, open box.

Hold the toy steady

Stop rolling toys from disappearing beneath furniture.

You may be able to stabilise a food toy against a folded towel, provided your dog can still use it safely.

Move to a non-slip surface

A dog who is sliding may not be able to concentrate comfortably.

Increase the distance between dogs

Food competition can increase speed, tension and guarding.

Separate dogs completely where necessary.

Shorten the session

A few minutes can be enough.

Stop while your dog is still coping.

Return to a familiar activity

If a new puzzle is difficult, offer something your dog already understands.

That may be scatter feeding, a simple “find it” game or an ordinary bowl meal.

My Indoor Brain Games for Dogs guide includes several activities that can be simplified for beginners.

When to stop the game

Stop immediately when:

your dog begins swallowing material
the toy breaks
pieces come loose
the dog becomes highly distressed
your dog guards the item
conflict develops between pets
your dog redirects aggression
the activity causes pain
your dog struggles to breathe
your dog chokes
your dog becomes weak or unwell
food within the toy is unsuitable
the puzzle cannot be made safe

Also stop when your dog repeatedly chooses to leave.

They do not need to complete the activity.

Do not keep calling them back.

Do not push the item towards them.

Do not hold them beside it.

Walking away is a valid choice.

Food-puzzle safety

Food puzzles range from simple slow feeders to boards with sliding compartments.

Choose a puzzle that:

suits your dog’s size
has no pieces they can swallow
remains stable
can be cleaned properly
starts at an easy level
does not trap your dog’s tongue, tooth or paw
uses dog-safe materials
has no sharp, damaged edges

Blue Cross recommends supervising dogs while they use puzzle feeders.

Begin with compartments open.

Place food where your dog can easily reach it.

Increase the difficulty only when your dog remains relaxed.

Avoid buying a product solely because it is described as advanced.

Your dog does not receive extra benefit from struggling.

An interactive puzzle feeder for beginners on Amazon may be appropriate for dogs who already enjoy simple problem-solving.

Check the dimensions before buying.

A product designed for a small dog may contain parts that are unsafe for a larger dog.

Snuffle-mat safety

Snuffle mats can provide an easy scent search.

But they are not suitable for unsupervised chewing.

Use one safely by:

choosing an appropriate size
placing it on a stable floor
putting food near the surface at first
supervising your dog
separating other pets
removing it after the activity
checking the fabric regularly
washing and drying it properly

Stop if your dog:

pulls strips of fabric out
eats the material
carries the mat away
guards it
becomes frantic
struggles to find the food
slides across the floor

A dog snuffle mat on Amazon is one option for supervised food searches.

But a clean towel with visible food placed on top may be a safer starting point for a dog who has never used one.

Lick-mat safety

A lick mat can turn part of a meal into a slower activity.

However, some dogs lick calmly while others fold, bite or destroy the mat.

To use one safely:

choose the correct size
use suitable food
spread a thin layer
supervise your dog
place it within comfortable reach
remove it when the food is finished
check for damaged sections
wash it thoroughly

Do not leave it available as a general chew toy.

Remove the mat if your dog:

bites it
tries to tear pieces off
carries it away
guards it
becomes frustrated
must strain to reach it

A LickiMat Classic Dog Mat on Amazon is one reusable option.

Do not use foods containing xylitol, which may also appear on ingredient labels as birch sugar.

Speak to your vet when your dog has allergies, digestive problems or a prescribed diet.

KONG and food-toy safety

Rubber food toys can be useful when correctly sized and filled.

The KONG Classic Dog Toy on Amazon is widely available in different sizes and rubber strengths.

Choose a toy that cannot be swallowed whole.

Inspect it before every use.

Replace it when you see:

cracks
splits
missing pieces
deep tooth damage
weakened rubber
an enlarged opening

Begin with an easy filling.

For example:

Loose dry food
Dry food with a small soft plug
A loosely packed mixture
A chilled filling
A frozen filling once your dog understands the toy

A tightly packed frozen toy may last longer, but that does not automatically make it better.

It may cause:

frustration
hard biting
repeated throwing
excessive pawing
damaged teeth
loss of interest

Keep the opening and internal space clean.

Discard old food rather than leaving it inside.

My complete guide to KONG toys covers sizing, fillings, cleaning and different rubber types.

Cardboard and homemade enrichment safety

Cardboard boxes, tubes and paper can create low-cost enrichment.

But they need preparation and supervision.

Remove:

staples
tape
plastic windows
string
elastic bands
packaging labels
sharp edges
food residue
silica-gel packets
anything containing chemicals

Avoid boxes that previously held substances that could harm your dog.

Some dogs enjoy shredding cardboard without swallowing it.

Others eat everything they tear off.

Stop the activity if your dog consumes the material.

Keep homemade games simple.

An open box with several visible pieces of food may be enough.

Do not assume that several layers of paper provide better enrichment.

More layers can create frustration and increase the amount of material available to swallow.

My “Creating a Scent Box for Dogs” guide explains how to build the activity up gradually.

You can also read DIY Dog Toys for Enrichment for further supervised ideas.

Towel-game safety

A rolled towel game appears simple.

But a dog may:

pull it across the floor
bite the fabric
swallow threads
become frustrated by tight folds
slip while pawing it
guard it from another dog

Begin with the towel completely flat.

Place food openly on top.

When your dog understands the activity, fold one edge loosely over a piece of food.

Do not knot the towel.

Do not roll it tightly.

Use an old but intact towel without loose threads.

Supervise the game and remove the towel afterwards.

A flat towel search is still enrichment.

There is no requirement to make it harder.

Chew safety

Chewing can provide a suitable outlet for some dogs.

But “natural” does not automatically mean safe.

Choose chews and chew toys that:

suit your dog’s size
cannot be swallowed whole
do not splinter
are not excessively hard
fit your dog’s dental health
do not contain unsuitable ingredients
can be supervised

PDSA advises avoiding toys and chews that are harder than a dog’s teeth can safely manage.

It also advises avoiding bones and rawhide because of risks such as damaged teeth, choking, and gut blockages.

I do not recommend rawhide.

Hard antlers, bones and other very hard items can also damage teeth.

Speak to your vet when your dog has:

damaged teeth
gum disease
digestive problems
allergies
a medical diet
a history of swallowing objects
difficulty chewing

Remove any chew that becomes small enough to swallow.

Resource guarding and multi-dog homes

Food toys, puzzles, chews and resting spaces may become valuable to a dog.

Resource guarding can include:

freezing over the item
eating more quickly
hovering over it
blocking access
staring
showing the whites of the eyes
stiffening
growling
snapping
chasing another pet away
carrying the item somewhere hidden

Dogs Trust’s resource-guarding guidance explains that dogs may guard food, toys, chews and other valued resources.

Do not expect dogs to share enrichment equipment.

Give each dog their own activity in a separate space.

That might mean:

different rooms
secure barriers
closed doors
enough distance that they cannot watch one another

Children should not approach a dog using a food toy.

Do not repeatedly take enrichment items away to show your dog who is in charge.

This may increase worry about losing valuable things.

If you notice guarding:

give your dog space
keep other pets and people away
avoid reaching towards the item
manage access carefully
seek advice from a qualified reward-based professional

Do not punish growling.

A growl is a warning that your dog feels uncomfortable.

Food allergies, calories and medical diets

Food-based enrichment still counts as food.

It can quietly add a large number of calories when owners use:

treats
peanut butter
cheese
yoghurt
wet food
chews
biscuits
several food toys in one day

Where possible, use part of your dog’s normal meal allowance.

Keep extras small.

PDSA advises including treats and chews within a dog’s daily food allowance.

Speak to your vet before changing enrichment food when your dog:

is overweight
has allergies
has pancreatitis
has diabetes
has kidney disease
has digestive problems
follows a prescription diet
takes medication with food
is recovering from surgery
has reduced appetite

Check every ingredient.

Never use foods containing xylitol or birch sugar.

Also avoid grapes, raisins, chocolate, onions, garlic and other foods known to be unsafe for dogs.

My guide Ditch the Bowl at Mealtimes explains how to use a normal meal for enrichment without turning every activity into extra feeding.

Senior dogs and dogs with restricted movement

A brain game may involve more physical activity than you expect.

Puzzle boards can require:

repeated standing and lying down
paw lifting
bending
twisting
pushing
turning
chasing moving pieces

That may not suit a senior dog or a dog recovering from an operation.

Watch for:

slipping
stiffness
repeated position changes
reluctance to lower the head
holding up a limb
panting
trembling
moving away
increased discomfort later

Use a non-slip surface.

Place food within comfortable reach.

Choose stationary activities.

Follow veterinary restrictions exactly.

My Gentle Brain Games for Senior Dogs and Dogs on Restricted Exercise guide includes low-impact activities that can be adapted with veterinary approval.

Can dogs use enrichment toys when left alone?

Do not assume that an enrichment product is safe simply because it is sold for dogs.

A dog may use a toy calmly while you are present but chew on or destroy it when you are alone.

Supervise every new product until you know:

how your dog uses it
whether they bite it
whether pieces come loose
whether they guard it
whether it causes frustration
whether it becomes trapped
whether it can be swallowed
whether it increases distress when you leave

Fabric toys, snuffle mats, lick mats, cardboard games and puzzle boards are not automatically suitable for unsupervised use.

Some durable food toys may be suitable for certain dogs once carefully assessed.

But no toy is completely indestructible.

A food puzzle also does not treat separation anxiety.

Some distressed dogs will ignore food entirely. Others may eat quickly and then begin showing signs of distress.

Speak to your vet or an accredited behaviourist when your dog struggles to be left.

What to do if your dog swallows part of a toy

Contact your vet immediately if you know or suspect your dog has swallowed part of a toy, puzzle, fabric mat, towel, cardboard game or other unsuitable object.

Do not wait for symptoms.

Do not attempt to make your dog vomit unless a vet specifically instructs you to do so.

Tell the veterinary practice:

what was swallowed
the approximate size
the material
when it happened
your dog’s size
whether symptoms are present
whether any packaging or identical pieces are available

Possible signs of a blockage or other problem can include:

vomiting
reduced appetite
tiredness
abdominal pain
diarrhoea
constipation
difficulty passing stools
restlessness
a hunched posture

But serious problems can develop before obvious symptoms appear.

PDSA advises contacting a vet immediately when a dog swallows something unsuitable.

If your dog is choking or struggling to breathe, treat it as an emergency.

A simple enrichment safety checklist

Before the activity, ask:

Is this suitable for my dog’s size?
Does it fit their chewing style?
Is the difficulty appropriate?
Is the floor stable?
Is the food safe?
Does it fit their diet?
Are other pets separated?
Have I removed small or dangerous parts?
Is my dog physically comfortable?
Can they walk away?

During the activity, watch for:

calm investigation
regular success
relaxed movement
frustration
fear
guarding
physical discomfort
chewing or swallowing materials
damage to the product

After the activity:

remove damaged equipment
collect leftover food
wash reusable items
put fabric and cardboard away
check how your dog settles
account for the food used
note anything that needs changing next time

If the game repeatedly causes problems, choose a different activity.

Your dog does not need to master every puzzle.

How I choose enrichment during pet-care visits

I do not arrive with the same puzzle for every dog.

Before using enrichment, I consider:

what the owner has approved
what the dog already understands
their normal diet
allergies and medical conditions
guarding history
chewing style
age and mobility
other pets in the home
how the dog is behaving that day
whether they need activity or rest

Sometimes enrichment means scattering several pieces of familiar food across a clean towel.

Sometimes it means a calm sniff in the garden.

Sometimes the safest and most appropriate choice is no food game at all.

A dog who has had a stressful morning may need space and sleep rather than another challenge.

You can read about my canine enrichment visits in Finchley and solo dog walks in Finchley and Muswell Hill.

For nervous dogs who benefit from staying in familiar surroundings, I also offer house-sitting and in-home pet care.

Frequently asked questions

How can I tell if my dog is enjoying a puzzle?

Look for voluntary participation, calm sniffing, regular success and the ability to pause or walk away.

A dog who is barking, biting the puzzle or working with increasing force may be frustrated.

Is frustration good mental stimulation for dogs?

A small, manageable challenge may encourage problem-solving.

However, repeated failure, frantic behaviour or distress is not useful enrichment.

Make the activity easier before frustration builds.

Should I help my dog with a puzzle toy?

Yes.

You can open the compartments, reveal the food, or demonstrate an easier version.

Helping your dog does not spoil the activity.

Should I make the puzzle harder once my dog solves it?

Not automatically.

Many dogs enjoy repeating familiar activities.

Increase the difficulty only when your dog remains relaxed and appears to enjoy the challenge.

Why does my dog bark at puzzle toys?

They may be excited, frustrated, confused or worried about the object.

Make the puzzle easier by holding it still or removing it.

Do not assume barking means enjoyment.

Why does my dog bite the enrichment toy?

Your dog may be trying to reach inaccessible food, using their normal chewing style or becoming frustrated.

Stop if the product is being damaged or pieces could be swallowed.

Can dogs choke on puzzle toys?

Yes.

Toys and removable parts that are too small can pose a choking hazard.

Choose a product that suits your dog’s size and supervise its use.

I recommend separate food activities in separate spaces.

Sharing can create competition and resource guarding.

Can I leave a snuffle mat down all day?

No.

A snuffle mat may become a chew toy once the food is gone.

Supervise the activity and put the mat away afterwards.

Are homemade cardboard games safe?

They can be suitable under supervision when staples, tape, plastic and other hazards have been removed.

Stop if your dog swallows cardboard or other materials.

Is a frozen KONG better than an unfrozen one?

Not necessarily.

A frozen filling lasts longer but is more difficult to work with.

Begin with an easy filling and freeze it only when your dog already understands and enjoys the toy.

Why does my dog become more hyper after enrichment?

The activity may be too exciting, too difficult or unsuitable for that dog.

Reduce the difficulty, shorten the session, or choose a slower-sniffing or licking activity.

How long should a brain game last?

There is no fixed time.

A few minutes may be enough.

Stop while your dog is still comfortable, rather than waiting until frustration or exhaustion sets in.

Should I use my dog’s whole meal in a puzzle?

Only when the puzzle is easy enough and your dog can access the food comfortably.

For a beginner, use a small amount at first so the whole meal isn’t trapped inside a difficult toy.

Can enrichment toys damage teeth?

Very hard chews, damaged toys and forceful biting can injure teeth.

Choose suitable materials and speak to your vet when your dog has dental problems.

What should I do if my dog guards a food toy?

Give them space and keep people and other pets away.

Do not reach for the item or punish the dog.

Manage access and seek help from a qualified reward-based professional.

What should I do if my dog swallows part of a toy?

Contact your vet immediately.

Do not wait for symptoms and do not make your dog vomit unless specifically instructed by a vet.

Final thoughts

A brain game should not become a battle between your dog and a piece of plastic.

Your dog does not need to complete every puzzle.

They do not need to reach the greatest difficulty level.

And they do not need to work until they are exhausted.

Watch how they approach the activity.

Notice when their movements become faster, harder or less controlled.

Help before frustration takes over.

Reveal the food.

Open the compartment.

Hold the toy steady.

Or stop completely.

The best enrichment is not the game that lasts the longest.

It is the one your dog can use safely, understand comfortably and walk away from when they have had enough.
