Can dogs and cats eat cod?

Short answer: yes. Plain, boneless cod with nothing added is widely used in dog and cat food and treats. The details below are what matter.

Why cod works as a treat

• It's lean. Cod is a white fish with plenty of protein and very little fat compared with oily fish like salmon.
• It's a single protein. If you're keeping your pet's diet simple, a treat made only of cod is easy to account for.
• Pets tend to like the smell. That makes small pieces useful for training and for tempting picky eaters.

What to avoid

• Seasoning. Garlic and onion are toxic to dogs and cats, and salt, butter and oil don't belong in a pet's treat either.
• Breaded or fried fish. The coating and the frying fat add nothing your pet needs.
• Bones. Fish bones are small and sharp. Only give boneless cod.
• Salt cod. Cured, salted cod is far too salty for pets.

How much is okay?

Treat cod as a treat. A common rule of thumb from vets is that treats should make up no more than about 10% of a pet's daily calories, with the rest coming from a complete and balanced food. Fish on its own isn't a complete diet for dogs or for cats.

Start with a small piece the first time, as you would with any new food, and see how your pet does.

Dogs and cats: any difference?

Both can enjoy cod. Cats and small dogs do better with smaller pieces, so break larger bites up before serving. Always keep fresh water available, especially with dried treats.

If your pet has a food allergy, a health condition or a vet-prescribed diet, check with your vet before adding any new treat, including fish.
