How much is okay?
Think of feta as a rare garnish, not a training stash.
Rule of thumb: treats of all kinds should stay under ~10% of daily calories.
How to prepare them
- Offer plain feta only — rinsed if very briny; no herb oil or garlic.
- Crumble tiny amounts; don’t toss a cube they can gulp.
- Skip Greek salad leftovers, spanakopita, and herb-marinated feta jars.
- If your dog is lactose-sensitive, skip dairy entirely.
Risks & exceptions
- Salt — feta is a brined cheese and often very sodium-dense.
- Fat — rich cheese can trigger GI upset or pancreatitis-prone dogs.
- Lactose — many dogs don’t handle dairy well.
- Seasoned cheeses — garlic, onion, and herb-oil marinades are unsafe.
If your dog ate a lot
A pea-sized crumb is usually not serious. Larger salty/fatty portions can mean vomiting, thirst, or diarrhea.
- Mild: soft stool, temporary gas, thirst
- Call your vet if: repeated vomiting, lethargy, or your dog has pancreatitis history

FAQ
Is feta lower lactose than soft cheese?
Feta is still a fresh-ish brined cheese — lactose and salt both matter, and sensitive dogs can react.
Can puppies eat feta?
Best to avoid. Stick to puppy-appropriate treats.
What about marinated feta?
Skip — oil, herbs, garlic, and extra salt make it a bad idea.
Can dogs eat Parmesan instead?
Same caution: tiny plain amounts only, if at all — see our Parmesan page for the aged-cheese version.
