Are conkers poisonous to dogs and cats?
Cause sickness and can get stuck in the gut.
Why it's a problem
Conkers contain a poison called aesculin that causes sickness and diarrhoea. They are also hard and the right size to cause a blockage in the gut, which may need surgery.
Signs to look out for
- Being sick
- Diarrhoea
- Tummy pain
- Being off food, or straining to poo
What to do
Call your vet, especially if your dog ate a whole conker or several, or is being sick again and again.
