Is cheese safe for dogs?

In small, occasional amounts, yes for most dogs. Cheese is high in fat and salt, so it should be a training treat, not a meal — and dogs that are lactose intolerant, overweight or prone to pancreatitis should skip it.

Which cheese is best for dogs?

Lower-fat, lower-salt options like mozzarella or a little plain cottage cheese. Aged cheeses contain less lactose but more salt and fat — keep portions tiny either way.

Why can't dogs eat blue cheese?

Blue cheeses like Stilton and Roquefort can contain roquefortine C, a mold byproduct that can cause vomiting, tremors and seizures in dogs. There's no reason to take the risk.

Can puppies eat cheese?

A tiny piece as a training reward is generally fine, and many trainers use it. Puppies have more lactase than adult dogs, but their stomachs are also easier to upset — start with crumbs and watch the result.

Cheese is a treat, not a food group

Most dogs love cheese and tolerate small amounts well, which is why it’s a classic high-value training reward and pill-hider. The caution flag is about quantity and the individual dog: cheese is dense in fat, calories and salt.

When cheese becomes a problem

Lactose intolerance. Adult dogs produce less lactase than puppies. Dogs that get gas, soft stool or diarrhea after dairy should skip cheese — though hard, aged cheeses contain relatively little lactose.

Fat. Regular cheese contributes quickly to weight gain, and a large fatty binge can trigger gastrointestinal upset or pancreatitis in susceptible dogs.

Salt. Cheese is one of the saltier things in your fridge; dogs with heart or kidney conditions should avoid it.

Blue cheese. Roquefort, Stilton and similar molds can contain roquefortine C, which can cause vomiting, tremors and seizures in dogs. Blue cheese is the one cheese to treat as off-limits, full stop.

How to feed cheese safely

Keep pieces pea-sized, keep them occasional, and prefer lower-fat options like mozzarella or a spoon of plain cottage cheese. If you’re using cheese heavily for training, subtract those calories from the day’s food. When in doubt about your dog’s waistline or pancreas history, ask your vet — or pick carrots as the zero-guilt alternative.

If your dog ate it

If your dog raided a large amount of cheese — or any amount of blue cheese — and shows vomiting, tremors or weakness, call your vet.

In the US you can also call the ASPCA Animal Poison Control Center at (888) 426-4435 (a consultation fee may apply).
