Dogs Trust issues warning as autumn conkers pose serious risk to dogs

As autumn leaves begin to fall, Dogs Trust is urging owners to stay alert during walks — warning that conkers and acorns could make dogs seriously ill, and in some cases, prove fatal.

Conkers, the hard, shiny seeds of horse chestnut trees that blanket parks and woodlands at this time of year, may be a familiar sign of the season — but the charity says they can cause severe poisoning if chewed or swallowed by dogs.

Victoria Phillips, Veterinary Surgeon Manager at Dogs Trust, explained:

“Conkers might be a sign that autumn is here, but it is vital that dog owners understand that conkers and acorns can be toxic to dogs and, in some cases, can even be deadly.”

She added:

“Bigger dogs might swallow them, and smaller pooches might give them a chew, both of which can have some nasty side effects!”

Conkers contain a toxin known as aesculin, which can make dogs unwell within just a few hours of ingestion. Symptoms include vomiting, diarrhoea, stomach pain, restlessness, rash, swelling around the eyes and mouth, and even collapse in severe cases.

Dogs Trust warns that as well as poisoning, conkers and acorns can also cause choking or dangerous gut blockages, particularly in smaller breeds.

To help prevent harm, the charity is encouraging owners to take extra care on autumn walks.

“To keep your dog safe this autumn, walk your dogs on a lead where there are lots of conkers on the floor, and keep your eyes peeled for your pooch playing with them. They may look relatively harmless, but they can cause serious issues,” said Ms Phillips.

Anyone who suspects their dog has eaten conkers or acorns, or is showing signs of illness, should contact a vet immediately.
