Why
Cheese is not toxic, and many trainers use tiny pieces as a high-value reward. However, it is high in fat and calories, and it contains lactose, which many adult dogs do not digest well.
Some cheeses are riskier than others. Blue cheeses can contain a mold toxin called roquefortine C, and flavored cheeses may contain garlic, onion or chives. Dogs that are overweight or have had pancreatitis should avoid fatty treats like cheese.
Risks to watch for
- Diarrhea, gas or vomiting in dogs that are lactose intolerant
- Weight gain with regular use
- Pancreatitis risk in dogs prone to it
- Added garlic, onion or herbs in flavored cheeses
How to share safely
- Pick plain, lower-fat options such as mozzarella or cottage cheese.
- Cut into small pieces, especially for training.
- Avoid blue cheese, heavily salted cheese and cheese with added flavors.
How much?
A few small cubes at a time. Treats of all kinds should make up no more than about 10% of daily calories.
