Can Dogs Eat Cheese? Lactose, Fat & Safe Portions
Vet-reviewed via PetHealth+ · Last reviewed July 2026
Is cheese safe for dogs?
Cheese is not a classic poison like chocolate, grapes, or xylitol. The issues are digestibility and calories:
- Adult dogs often produce less lactase, so lactose can cause gas, bloating, and diarrhoea
- Most cheeses are energy-dense and fatty — a risk for weight gain and pancreatitis
- Seasoned or stuffed cheeses may hide onion, garlic, chives, or other unsafe add-ins
Used carefully, a pea-sized cube can be a high-value training reward. Used carelessly, cheese becomes a tummy-upset machine.
Lactose intolerance in dogs
Signs that dairy does not agree with your dog:
- Soft stools or diarrhoea
- Excess gas
- Belly discomfort or rumbling
- Occasional vomiting after cheese
Harder, aged cheeses are often lower in lactose than milk, but fat content may still be high. Cottage cheese (low-fat) is frequently better tolerated in small spoonfuls — still not a free-for-all.
Better vs worse cheese choices
| Better (tiny portions) | Avoid or be very careful |
|---|---|
| Low-fat cottage cheese | Blue cheese / mould-ripened |
| Plain mozzarella | Mac & cheese leftovers |
| Low-fat soft cheese (plain) | Cheese with garlic/herbs |
| Tiny cheddar cube (if tolerated) | Cream cheese frostings with xylitol |
Never share cheese that contains grapes/raisins, onion/garlic, chocolate, or xylitol sweeteners. See foods dogs cannot eat.
Portion rules
- Treats (including cheese) ≤ ~10% of daily calories
- Training: use crumb-sized bits, not sandwich slices
- Frequency: occasional — not every meal
Dogs on weight-loss or low-fat veterinary diets usually should not get cheese at all.
When to skip cheese entirely
- History of pancreatitis
- Known dairy sensitivity
- Obesity or calorie-restricted plan
- Kidney disease diets that limit certain nutrients (ask your vet)
- Any cheese product with toxic mix-ins
If your dog stole a large block of cheese and develops vomiting, painful belly, or lethargy, contact your vet — fatty food binges can trigger serious GI disease even without a “toxin.”

Frequently asked questions
Can dogs eat cheese?
Many dogs tolerate small amounts of low-fat cheese as an occasional treat. Lactose intolerance and high fat mean cheese is not ideal for every dog — start tiny and watch for diarrhoea or gas.
What cheese is safest for dogs?
Low-fat cottage cheese or mozzarella in tiny cubes are common choices. Avoid blue cheese, heavily seasoned cheeses, and anything with onion, garlic, or xylitol.
Can puppies eat cheese?
Only in very small amounts if at all. Puppies need balanced growth diets; rich dairy can upset their stomachs.
Is cheese bad for dogs with pancreatitis?
Often yes — high-fat cheeses can trigger or worsen pancreatitis. Follow your vet’s fat-restricted plan and skip cheese unless cleared.
