Can Dogs Eat Cheese? Best Types and Lactose Intolerance Guide

Cheese is one of the most effective training treats for dogs — but not all cheese is equal. Type, fat content, and your dog's lactose tolerance all matter.

Is Cheese Safe for Dogs?

Yes — for most dogs, cheese in small amounts is safe and even beneficial. It is one of the most widely used training treats among professional dog trainers, and for good reason: cheese has a strong aroma, a texture dogs love, and a high value as a reward that persists even in distracting environments.

However, not all dogs tolerate dairy equally, and not all cheeses are appropriate. The key variables are fat content, lactose content, and whether the cheese contains any added ingredients that could be harmful. Blue cheese stands apart from all other varieties — it poses a genuine toxicity risk and should never be given to dogs regardless of amount.

For healthy adult dogs without known dairy sensitivity, mild low-fat cheeses in modest amounts are a safe, versatile, and nutritionally non-trivial treat.

Lactose Intolerance in Dogs

Lactose intolerance in dogs is more common than most owners realize. Puppies produce the enzyme lactase to digest their mother's milk, but lactase production typically decreases as dogs mature into adulthood. Many adult dogs have limited ability to break down lactose — the sugar naturally present in dairy.

The good news: the fermentation process that produces hard aged cheeses consumes most of the lactose. Cheddar, swiss, parmesan, and similar aged hard cheeses contain far less lactose than fresh soft cheeses like ricotta or cream cheese. This makes them a better starting point for dogs of unknown dairy tolerance.

Signs of lactose intolerance after cheese include loose stools or diarrhea, flatulence, borborygmi (audible stomach gurgling), and occasionally vomiting. These symptoms typically appear within a few hours of eating dairy. If your dog shows any of these signs after eating cheese, reduce the amount or switch to a lower-lactose variety such as hard aged cheddar.

Some dogs tolerate all dairy well; others react even to small amounts of any dairy product. Introduce cheese slowly and observe your dog's response before making it a regular part of their treat rotation.

Best Types of Cheese for Dogs

Not all cheese is equal when it comes to dogs. Here are the best options ranked by digestibility and safety, followed by the varieties to avoid.

1. 1
   Low-fat cottage cheeseThe top recommendation from many vets. Easiest to digest, relatively low in fat, and often used during GI upset recovery alongside a bland diet. Choose plain, unseasoned cottage cheese with no added herbs or onion.
2. 2
   Part-skim mozzarellaMild flavor, lower fat than whole-milk mozzarella, and relatively low lactose. Easy to break into pea-sized training treats. String cheese is a convenient pre-portioned version.
3. 3
   String cheeseConvenient, consistent treat size and mild flavor. Made from part-skim mozzarella — same benefits. Easy to tear into small portions for training sessions.
4. 4
   Mild cheddarWidely tolerated and low in lactose due to the aging process. The sharp flavor makes it highly appealing even in tiny amounts, so you can use less. Avoid extra-sharp or very aged varieties, which are higher in fat.
5. 5
   Swiss or goudaBoth are lower in lactose than most fresh soft cheeses, making them a reasonable option for lactose-sensitive dogs. Use in small amounts.

Pancreatitis Risk

Pancreatitis — inflammation of the pancreas — is one of the most common dietary-related emergencies in dogs, and high-fat foods are a leading trigger. Cream cheese, brie, extra-aged extra-fat cheddar, and similar rich varieties can precipitate an acute episode when fed in quantity.

Certain breeds are particularly predisposed to pancreatitis and should receive dairy treats with extra caution: Miniature Schnauzers, Yorkshire Terriers, Cocker Spaniels, and Shetland Sheepdogs have elevated genetic and statistical risk. For these breeds, it is especially important to keep cheese to very small amounts and to choose the lowest-fat options.

Signs of pancreatitis include vomiting, hunched posture, reluctance to eat, abdominal pain, and lethargy, typically appearing 1–4 days after the triggering meal. If you observe these symptoms, contact your veterinarian promptly. Pancreatitis ranges from mild and self-limiting to severe and life-threatening.

Cheese as a Training Tool

Cheese earns its reputation as a high-value training reward. Dogs respond strongly to its aroma and flavor, making it effective even in high-distraction environments where standard treats lose their appeal. This makes it particularly useful for recall training, loose-leash walking in busy areas, and introducing dogs to novel or frightening stimuli.

The practical approach: pre-cut mild cheddar or string cheese into pea-sized pieces before a training session. Small pieces allow for many repetitions without exceeding calorie or fat limits. For a 30-minute training session, 20–30 pea-sized pieces of mild cheddar is appropriate for most medium-sized dogs.

Low-fat cottage cheese also works well spread on a lick mat during Kong stuffing or as part of a frozen enrichment activity. Its softer texture makes it ideal for dogs with dental sensitivities or older dogs who have difficulty with harder treats.
