Lactose Intolerance in Dogs

Many dogs produce less lactase (the enzyme that breaks down lactose) as they mature. While most dogs can tolerate small amounts of cheese โ€” especially aged varieties like cheddar which contain very little lactose โ€” some dogs are more sensitive. Signs of lactose intolerance include bloating, gas, loose stools, and stomach gurgling.

If you’re unsure, start with a tiny piece of cheddar or cottage cheese and watch for any digestive reaction over 24 hours.

Why Is Blue Cheese Dangerous?

Blue cheeses like Stilton, Roquefort, and Gorgonzola produce a substance called roquefortine C during the moulding process. This mycotoxin can cause vomiting, diarrhoea, tremors, and seizures in dogs. If your dog eats blue cheese, contact your vet.

Cheese as a Training Treat & Pill Pocket

Small cubes of cheddar are widely regarded as one of the best high-value training treats. The strong scent and taste make them irresistible to most dogs. Cheese is also excellent for hiding tablets โ€” wrap the pill in a soft piece of cheese for stress-free medication time.

Frequently Asked Questions

How much cheese can I give my dog?

Cheese should make up no more than 10% of your dog’s daily calories. For a medium-sized dog, this is roughly 2โ€“3 small cubes (about 30g) per day. It’s best used as a treat, not a regular meal component.

Can cheese cause pancreatitis in dogs?

High-fat cheeses like brie, camembert, and cream cheese can trigger pancreatitis, especially in dogs prone to the condition. Stick to lower-fat options like cottage cheese or mozzarella if your dog has a sensitive stomach.

Is cheese safe for puppies?

Small amounts of mild cheese are generally safe for puppies over 12 weeks. Start with a pea-sized piece to check for any intolerance. Cottage cheese is the best option for puppies due to its low fat and lactose content.
