Is Mozzarella Safe for Dogs?
Veterinary and pet-nutrition organisations generally classify mozzarella as non-toxic to dogs. It is not listed as poisonous by veterinary toxicology authorities.
However, mozzarella is consistently described as a food requiring caution. The AKC and PetMD explain that cheese is a dairy product, and many dogs have difficulty digesting lactose. VCA Hospitals notes that lactose intolerance is common in dogs, particularly after weaning.
Across veterinary guidance, concerns focus on digestion, fat content, and individual tolerance, not toxicity.
Why Mozzarella Can Be a Problem for Some Dogs
Lactose content
Veterinary sources explain that mozzarella contains lactose, which may cause gastrointestinal upset in lactose-intolerant dogs.
Fat levels
Pet-nutrition articles note that mozzarella contains fat, which may contribute to vomiting or diarrhoea in some dogs.
Salt content
Veterinary guidance highlights sodium as a concern in cheeses, particularly when consumed in larger quantities.
Signs Reported When Dogs React Poorly to Mozzarella
Veterinary sources describe the following signs associated with dairy intolerance:
- Diarrhoea
- Vomiting
- Gas
- Abdominal discomfort
These effects are linked to digestion rather than poisoning.
Ingredients or Additives to Watch For
Mozzarella products may vary significantly in formulation:
- ⚠️ High-fat versions, which may worsen digestive upset
- ⚠️ Added salt, common in processed mozzarella
- ❌ Seasoned or flavoured mozzarella, which may contain garlic or onion
Concerns depend on processing and added ingredients rather than the cheese itself.
Puppies vs. Adult Dogs
Veterinary literature notes that puppies may digest lactose more easily than adult dogs, but this tolerance often decreases with age. Adult dogs are more likely to experience lactose intolerance.
Other Cheeses Discussed in Veterinary Sources
Cheddar
Often discussed with similar lactose and fat considerations.
Goat cheese
Veterinary sources note differences in lactose content but still discuss digestive sensitivity.
Cream cheese
Discussed as higher risk due to fat content.
Dairy Foods Mentioned in Pet-Nutrition Literature
Veterinary and pet-nutrition articles frequently reference these dairy products:
- Mozzarella
- Cheddar
- Yogurt
- Milk
Discussions consistently focus on lactose intolerance and fat content rather than toxicity.
