Can Dogs Eat Cheese?

Safe serving sizes

A good rule: cheese should never account for more than 10% of a dog’s daily calories. For a 20‑pound dog that means about 20 kcal from treats, which equals roughly one small cube of cheddar (PetMD (pet health resource)). Piece size matters too — cut cheese into pea‑sized chunks to avoid choking and to keep calories low.

Benefits of cheese for dogs

Risks of feeding cheese

Cheese is high in fat and calories. Regularly exceeding the 10% treat limit can lead to obesity and, in susceptible dogs, pancreatitis. Many dogs are also lactose intolerant, and too much cheese can trigger gas, bloating, or diarrhea (PetMD (pet health resource)). The risk is highest for breeds like Miniature Schnauzers and Shetland Sheepdogs that are genetically predisposed to pancreatitis.

The trade-off

Cheese’s high value as a training treat comes at a cost: even small daily pieces add up. Owners who use cheese for training should reduce other treats and account for those calories in the dog’s overall diet.

The implication: owners must weigh reward against cumulative calories and fat intake.

What kind of cheese is safe for dogs?

Low‑lactose cheeses

Aged cheeses naturally contain very little lactose because the aging process breaks down milk sugars. Cheddar, Swiss, and Parmesan are all safe options with less than 0.5 g of lactose per ounce (Wellspring Veterinary (veterinary hospital)). Fresh cheeses like mozzarella and cottage cheese have slightly more lactose but are still widely tolerated.

Hard vs soft cheeses

Hard cheeses (cheddar, Swiss) are generally lower in moisture and fat than soft cheeses (brie, camembert), making them a more calorie‑controlled choice. Soft, mold‑ripened cheeses carry an extra risk because they may harbor mycotoxins.

Safe list: cheddar, mozzarella, Swiss, cottage cheese

  • Cheddar — low lactose, widely available, moderate fat (Mendocino Animal Hospital (veterinary practice))
  • Mozzarella — low in fat and lactose (PetMD (pet health resource))
  • Swiss — lower sodium than most cheeses, good for salt‑sensitive dogs (Wellspring Veterinary (veterinary hospital))
  • Cottage cheese — low fat, low sodium varieties are easiest on the stomach (American Kennel Club (veterinary-reviewed guide))
Bottom line: Owners should stick with plain, aged, or low‑fat cheeses. Avoid any cheese that lists garlic, onion, herbs, or artificial flavourings — those additives are dangerous even in small amounts.

The consequence for dog owners: choosing the right cheese reduces health risks while still allowing a tasty reward.

What foods are poisonous to dogs?

Cheeses to avoid: blue cheese, Roquefort, cheese with additives

Blue cheese and its relatives (Roquefort, Gorgonzola, Stilton) contain roquefortine C, a mycotoxin that can cause muscle tremors, vomiting, and even seizures in dogs (PetMD (pet health resource)). The risk is highest when the cheese is moldy, but even fresh blue cheese is not worth the gamble.

Other common toxic foods: chocolate, grapes, onions, garlic

  • Chocolate — contains theobromine, toxic to dogs
  • Grapes and raisins — can cause acute kidney failure
  • Onions and garlic — damage red blood cells and lead to anemia (PetMD (pet health resource))
  • Xylitol — an artificial sweetener found in some cheese spreads; causes rapid insulin release and hypoglycemia

Symptoms of food poisoning in dogs

Signs to watch for: vomiting, diarrhea, lethargy, drooling, tremors, or loss of appetite. If your dog eats any of the foods listed above, contact your veterinarian or an animal poison control center immediately.

What to watch

A single cube of blue cheese may contain enough roquefortine C to trigger symptoms in a small dog. The catch: symptoms can appear up to 12 hours later, so owners may not connect the treat to the illness.

The pattern: awareness of delayed symptoms is critical for timely treatment.

What can dogs not eat cheese?

Cheese with mold

Any moldy cheese poses a risk of mycotoxin poisoning. Beyond blue cheese, soft, aged cheeses like brie and camembert can also harbor harmful molds. If you wouldn’t eat it yourself, don’t give it to your dog.

Cheese with high salt

Feta, halloumi, and many processed cheeses are extremely high in sodium. Too much salt can lead to sodium ion poisoning, causing excessive thirst, urination, and in severe cases, seizures (Wellspring Veterinary (veterinary hospital)).

Cheese with herbs and spices

Garlic, onion, chives, and other seasonings are toxic to dogs regardless of quantity. Always check the ingredient list before sharing even a small piece of flavored cheese.

Bottom line: Dog owners should keep cheese away if it isn’t plain, because added herbs, spices, or mold can lead to a vet visit.

The consequence: vigilance with ingredients prevents avoidable poisoning.

What happens when a dog eats cheese everyday?

Weight gain and obesity

One ounce of cheddar packs 113 calories. For a 20‑pound dog whose daily calorie needs are around 400–500 kcal, a single ounce of cheese already pushes past the 10% treat limit. Daily feeding quickly leads to extra pounds (PetMD (pet health resource)).

Digestive issues from lactose

Many adult dogs lose the ability to digest lactose after weaning. Daily cheese can cause chronic gas, bloating, and soft stools. The problem is worse with fresh cheeses (mozzarella, ricotta) that retain more lactose (American Kennel Club (veterinary-reviewed guide)).

Risk of pancreatitis

High‑fat foods trigger pancreatitis in susceptible breeds. Daily cheese consumption raises that risk, especially in dogs with a history of pancreatic issues. Once pancreatitis develops, lifelong dietary restrictions are often required. For a comprehensive guide on safe cheeses and potential risks, see Matt Walsh comentador família fe.

Behavioral issues with treat dependency

Using cheese as a daily training tool can create expectation behaviors — dogs may refuse lower‑value treats or perform only when cheese is visible. Rotate treats to keep high‑value rewards special.

The paradox

Cheese’s very strength as a training aid — its irresistible smell and taste — is also its risk when used daily. The more valuable the reward, the harder it is to wean the dog off it.

What this means for owners: daily cheese use trades training convenience for long-term health and behavior costs.

Upsides

  • High‑value training treat — motivates even stubborn dogs
  • Provides protein and calcium in small amounts
  • Low‑lactose options (aged cheddar, Swiss) are well tolerated
  • Easy to portion into tiny pieces

Downsides

  • High fat content can cause pancreatitis
  • Calorie density leads to weight gain
  • Lactose may cause digestive upset
  • Additives like garlic, onion, or xylitol are dangerous
  • Creates treat dependency if used daily

Clarity breakdown

Confirmed facts

  • Dogs can eat cheese in moderation (American Kennel Club (veterinary-reviewed guide))
  • Blue cheese is dangerous due to roquefortine C (PetMD (pet health resource))
  • Aged cheeses have less lactose than fresh cheeses (Wellspring Veterinary (veterinary hospital))

What’s unclear

  • Exact amount that triggers pancreatitis in individual dogs varies
  • Long‑term effects of regular cheese treats are not well studied
  • Safe threshold for dogs with existing pancreatitis is unknown

Cheese can be a great high‑value treat for training, but owners should be mindful of fat content and portion size.

— Expert from the American Kennel Club

Many cheeses are safe, but avoid those with added ingredients like garlic or onions — they can be toxic to dogs.

The decision to share cheese with your dog isn’t a straight yes or no — it depends on the type, the amount, and your dog’s health. For the average healthy dog, an occasional cube of plain cheddar or mozzarella is fine. But for dogs with pancreatitis, obesity, or lactose sensitivity, even a small piece can cause problems. The safest approach: choose low‑fat, low‑lactose cheeses, keep portions tiny, and never let cheese replace a balanced diet. For dog owners, the choice is clear: use cheese as an occasional high‑value reward, not a daily staple — or risk unwanted weight, digestive trouble, and a picky eater.

Frequently asked questions

Can dogs eat cheese if they are lactose intolerant?

Most lactose‑intolerant dogs can handle small amounts of aged cheese (like cheddar or Swiss) because the aging process removes most of the lactose. Fresh cheeses like mozzarella or cottage cheese are more likely to cause gas or diarrhea. Start with a tiny piece and watch for reactions.

How much cheese can I give my dog?

Cheese should make up no more than 10% of your dog’s daily calorie intake. For a 20‑pound dog, that’s about 20 kcal — roughly one small cube (½ inch) of cheddar. Adjust based on your dog’s size and activity level.

Can puppies eat cheese?

Yes, in small amounts. Puppies have even more sensitive stomachs, so stick to low‑fat cheeses like cottage cheese or mozzarella. Use tiny pieces as training rewards. Avoid any cheese with added ingredients.

Is cheese good for dog training?

Yes — cheese is a high‑value treat because most dogs find it extremely palatable. Cut it into pea‑sized pieces and use it sparingly for difficult commands. Rotate with other low‑calorie treats to maintain its special status.

What is the best cheese for dogs with sensitive stomachs?

Cottage cheese (low‑fat, plain) is often the best choice because it’s low in fat, sodium, and relatively low in lactose. Swiss cheese is also a good option due to its lower sodium content. Avoid fresh, soft cheeses and any with seasonings.

Can dogs eat cream cheese?

Plain cream cheese in very small amounts is not toxic, but it’s high in fat and often contains additives like garlic or onion powder. It also has moderate lactose. If you share it, keep the portion tiny — less than a teaspoon for a medium‑sized dog.

Does cheese cause diarrhea in dogs?

Yes, if given in excess. The lactose in cheese can cause osmotic diarrhea in dogs that don’t produce enough lactase. Even small amounts may trigger loose stools in sensitive dogs. If diarrhea occurs, stop giving cheese and consult your vet if it persists.
