Can dogs eat it?

Can dogs eat blue cheese?

No, toxic No. Blue cheese is made with a mould and contains roquefortine C, which can cause tremors and seizures in dogs.

Why

Blue cheese is made using a fungus that dogs can be sensitive to (PDSA), and it contains roquefortine C, which RSPCA says is toxic to pets. RSPCA says the tremors and seizures it can cause may last days. Like other cheese, it is also fatty.

Signs to watch for

If your dog ate blue cheese

Take your dog to the vet straight away if they have eaten blue cheese (RSPCA).

If your dog has eaten something toxic

Call your vet or the nearest emergency vet now. Do not wait for signs, and do not make your dog sick unless a vet tells you to. Take the packet with you.

This is general guidance, your vet sets the actual schedule. Puppies, small dogs and dogs with a health condition can react to smaller amounts. Check with your own vet before changing what your dog eats.

Other foods people ask about

Butter Only with care Only a lick. Butter is very fatty, and a large amount can cause vomiting, diarrhoea or pancreatitis. Cheese Only with care A small cube of plain cheese is fine for most dogs. It is fatty, some dogs cannot digest it, and never give blue cheese. Ice cream Only with care Best avoided. Ice cream is sugary and hard to digest, chocolate flavours are toxic, and sugar-free ones can contain xylitol. Milk Only with care Best not. Many dogs cannot digest lactose well, and RSPCA Australia says not to give dogs or puppies milk. Water is all they need. Yoghurt Only with care Plain, unsweetened yoghurt in small amounts suits many dogs. Never flavoured, sweetened or "light" yoghurt that may contain xylitol.
