Are cheese and milk poisonous to dogs and cats?
Not poisonous, but many pets can’t digest milk well. Small amounts of cheese are usually fine.
Why it's a problem
Many adult cats and dogs are lactose intolerant, so milk can cause diarrhoea. Cheese has less lactose but is high in fat and salt. Blue cheeses contain a mould that can make dogs unwell.
Signs to look out for
- Diarrhoea
- Wind
- Being sick
What to do
No action is usually needed. Call your vet if they ate blue cheese, or a lot of cheese, and seem unwell.
