Can dogs eat cheese?

Caution — small amounts only

Small amounts of plain cheese are usually fine for most dogs, but many dogs are mildly lactose intolerant. Avoid blue cheese entirely.

The full picture

Cheese is a useful high-value training treat because most dogs love it, but it should be used sparingly. Dogs don't produce much lactase, so dairy can cause digestive upset. Harder, lower-lactose cheeses like cheddar and mozzarella are better tolerated than soft cheeses. Blue cheese (stilton, roquefort, gorgonzola) must be avoided — it contains a mould that produces roquefortine C, which is toxic to dogs. Cheese is also high in fat and salt, so small amounts only, especially for dogs prone to pancreatitis.
