Can Dogs Eat Fish Oil Supplements?
Why it’s a sometimes-food
Omega-3s from fish oil support skin, coat, joints and heart health, and vets recommend it widely for dogs. Too much causes loose stools and vomiting in the short term, and chronically high doses add calories and can affect blood clotting. Human capsules work but must be dosed for the dog’s weight.
How to serve it safely
Use a veterinary or pet-labeled fish oil and follow weight-based dosing on the label. Pierce capsules over food or use liquid pumps, and start low.
Warning signs to watch for
Overdose shows as greasy stools, diarrhea, vomiting and bad breath; very high chronic doses can impair platelet function.
When to call the vet
Ask your vet for the right EPA and DHA dose for your dog, especially before surgery or with clotting disorders.
Common questions
Can I use my own fish oil capsules?
Yes — the EPA and DHA are the same. Dose by your dog’s weight, not by the human serving on the label.
Can I skip supplements and just feed sardines?
Regular small oily fish covers much of the same ground — a simple, food-first way to get omega-3s.
