Many dog owners are unaware of the danger.

Dog owners have been reminded to be alert to the dangers of conkers on their dog walks this autumn as the shiny brown seeds contain toxins that are harmful to dogs.

This comes as some experts note an earlier than usual conker drop brought on by the long, hot summer.

In fact, the organisers of the Northamptonshire based World Conker Championships which is held in October each year, have even resorted to freezing conkers collected in September to ensure adequate supplies for the competition next month.

Ross Hallifax from Purely Pets Insurance has cautioned that, with conker season already underway, it is important for dog owners to be aware of the risk they can pose to dogs.

Here’s what you need to know.

What are conkers?

Conkers are the seeds of a horse chestnut tree. These trees are easily recognisable thanks to their large hand shaped leaves, and the conkers have a green spikey case. Horse Chestnut or conker trees are common in parks, gardens and alongside roads.

Children traditionally collect them, tie them onto a piece of string and used them to play conkers, where the object of the game is to hit and destroy your opponent’s conker.

Why are conkers dangerous to dogs?

It is important that dogs do not chew or swallow conkers. They contain a toxin called aesculin which can cause symptoms including drooling and vomiting and in worst case neurological issues and collapse.

Because of their size, they could also cause blockages in a dog’s intestines or cause a choking hazard.

What are the symptoms of conker poisoning in a dog?

Animal welfare charity, Blue Cross advises that signs of illness can arise within one to six hours, but may also appear up to two days following your dog consuming conkers and the symptoms of conker poisoning can include:

  • vomiting
  • diarrhoea
  • restlessness with discomfort and abdominal pain
  • lethargy or tiredness
  • collapse
  • wobbliness and tremors.

What should I do to protect my dog?

Prevention is always best, so stay vigilant on walks with your dog if you notice Horse Chestnut trees nearby. If your dog has ingested a conker, you should contact your vet straight way.
