Foods bad for dogs that should also be kept avoided

The following foods that didn’t really fit into my A to Z above should also be avoided

Old Food

When food goes past its sell-by date or starts to sell not right as humans, we won’t eat it.

So why should we expect our dogs to want it?  As food gets older and starts to go bad, it contains all sorts of bacteria and toxins that can be bad for your dog’s health

It is important that you feed your dog  the freshest dog food you can or if you feed vegetables to your do they are also fresh


Please do not be tempted to feed your dog table scraps on a regular basis as this means they won’t get a proper diet.  When you do give the scraps as a treat make sure that  it doesn’t have any bone, has had the fat trimmed off and free from salt and other seasonings

Human snacks

Snacks such as crisps usually contain salt and ay contain onion power so are bad for your dog. 

Cookies can often contain coco powder, raisons etc so are also bad for dogs

Essentially feed your dog high quality dog treats that are specially made for dogs, and all will be fine.

Safety Tips when feeding people food to dogs

Before you give your dog a portion of human food, make sure it’s safe. Be aware of what he can and cannot eat and be cautious at all times. Don’t give your dog a diet of 100% human food. It’s very important that he receives the correct balance of nutrients. Ensure that he eats a balanced diet consisting of both a good quality kibble and people foodstuffs.  A great site to check out the quality is all about dog food

Begin any changes to his diet slowly. Offer your dog small amounts, to begin with, and keep to food products that are similar to the contents of his kibble food. Offer your dog only food that you would eat yourself. Chicken skin, gristle and fat, that you would generally leave on your plate are not for sharing with your pet.

When in Doubt, Ask A Vet

If you notice any strange behaviour or your dog shows signs of weakness, vomiting, lack of coordination or just acting very strangely, then please contact your vet for advice immediately

If your dog has eaten something it shouldn’t then the quicker the better chance of survival.

Conclusion about Toxic foods for dogs

While we consider our dogs to be part of our families, feeding them your food at mealtimes can cause serious problems to their health.

As we all know, dogs are quite expert at sniffing out food so be prepared not to leave any food items lying around within easy reach. If you think your dog has eaten a toxic food item, consult your Vet immediately or at the very least call VetFone.
