Be aware of the poison risk to dogs from Acorns and Conkers
Now that the nights are getting shorter, we know that autumn is just around the corner. With the mild weather, we’re able to take our dogs out walking in the countryside and in the woods in particular, there are several toxic risks that we need to be aware of. Both acorns and conkers can prove deadly for dogs, especially if eaten, causing them to be seriously ill, and in some severe cases, fatal.
In every case, if you think your dog has eaten something he shouldn’t, gather together as much evidence and information as you can for the Vet to help with the diagnosis.
Acorns (from the Oak)
During the autumn and winter months, exposure to acorns is quite common, as dogs will go sniffing through the undergrowth on their daily walks. If they do manage to eat acorns or the young oak leaves, damage to their kidneys and liver may be caused by tannic acid (gallotanin), the toxic ingredient in acorns.
Symptoms to look out for include being lethargic, increased thirst, abdominal pain, vomiting, diarrhoea which may be accompanied with or without blood and having no appetite. It is also possible that an intestinal blockage may be caused by ingesting acorns.
You also need be alert if any oak leaves or acorns have fallen into your dog’s water dish, as the poison can transfer to the water. It’s thought that the green acorns are more toxic than the brown variety and the larger the acorn “cap” the higher the amount of toxic acid it contains.
Conkers (from the Horse Chestnut)
It’s quite rare to see a severe case of poisoning in dogs, caused by eating conkers. They contain a poison named aesculin, found in all parts of the tree, including the leaves. Dogs would normally need to swallow a number of conkers for toxicity to occur.
Symptoms after ingestion may be abdominal pain, diarrhoea, vomiting, retching and drooling. The prickly outer case, and the conkers themselves pose a risk if eaten, resulting in an intestinal blockage. A dog who has eaten conkers will usually vomit them up quickly and it may be necessary to prescribe a treatment to control this severe vomiting.
Prevention is best
Although we know its nigh on impossible to watch your dog every minute of the day, it’s very important to try and make sure they are not allowed to either play with acorns or conkers, or in fact, eat them. Be very conscious of the symptoms of toxicity when walking your dog, and if you are in any way concerned about your dog, contact the Vet’s surgery immediately.
If you live in an area where there are oak trees, it may help to train your dog to the commands of “drop it” and “leave it”. It’s also a good idea to take along a favourite toy or some doggy treats to take the dog’s focus away from the acorns or conkers, especially when you’re going into areas where they have fallen on the ground.
