fish food
So you’re staring at your pup while you’re cooking fish and thinking: hmm, could I share this with you? Or maybe you’ve heard about fish food for dogs and you’re wondering if it’s actually good or just another internet trend. The short answer? Fish can definitely be awesome for dogs, but it’s not as simple as tossing them your leftovers. Let’s break it down so you know what’s safe, what’s not, and how to keep your four-legged buddy happy and healthy.
Is fish food good for dogs?
Yup, fish can be a really good thing for dogs — as long as it’s the right kind of fish and prepared the right way. Dr. Leslie Gillette, DVM over at PetMD says fish is “a great source of protein, low in bad fats, and easy to digest when cooked.” (source)
The American Kennel Club also gives it a thumbs up, especially because fish is packed with omega-3 fatty acids that can calm inflammation and keep joints feeling good. (source)
So yes — fish food can be great, but it depends on which fish and how often.
Benefits of fish food dogs
Alright, here’s why fish gets so much love from vets and pet parents alike:
- Lean, high-quality protein – Dogs need protein, and fish brings it without loading up on unhealthy fats. It’s also gentler on sensitive stomachs. (source)
- Omega-3s galore – These fatty acids help with skin, shiny coats, joint support, and even brain health. (source)
- Good for allergy pups – If your dog can’t handle chicken or beef, fish is often a safe “novel protein.”
- Better skin and coat – Less itchiness, fewer hot spots, and softer fur. Who doesn’t want a snuggle-worthy pup?
- Great for puppies and mamas – DHA in fish is important for brain and eye development. (source)
Can my dog eat fish every day?
Technically yes, but should you? Not without checking with your vet first. Fish every day can work if it’s a safe, low-mercury fish and part of a balanced diet. AKC suggests it’s fine in certain cases (like allergies or joint issues), but warns not to rely on just one protein forever. (source)
Think of it like pizza: eating it every day might sound amazing at first, but long term? Probably not the best idea.
How much fish to feed a dog per day?
Here’s a super handy guide to help you figure out portions:
| Dog Size | Serving Size of Fish* | Frequency |
|---|---|---|
| Extra-Small (2–20 lb) | ~1 oz (28 g) cooked fish | 2–3 times/week |
| Small (21–30 lb) | ~2–3 oz (56–85 g) | 2–3 times/week |
| Medium (31–50 lb) | ~4–5 oz (113–140 g) | 2–3 times/week |
| Large (51–90 lb) | ~6–8 oz (170–225 g) | 1–2 times/week |
| Extra-Large (90+ lb) | ~9–10 oz (255–280 g) | 1–2 times/week |
*Cooked, boneless, plain. No garlic butter, no fancy seasonings. Save those for yourself.
What fish should dogs avoid?
Not all fish is created equal. Here’s what to keep away from your dog’s bowl:
- High-mercury fish: Shark, swordfish, king mackerel, tilefish. Too risky. (source)
- Raw fish: Could carry parasites or bacteria (like salmon poisoning).
- Bony fish: Bones can cause choking or internal injuries.
- Fish loaded with additives: Garlic, onion, salt, oils, sauces — all bad news. (source)
Stick to the safe, simple stuff.
Can dogs live on a fish diet?
Only if a vet nutritionist builds it for them. A 100% fish diet can leave your dog missing key nutrients and expose them to mercury over time. Dr. Leslie Gillette notes fish should be part of the diet, not the whole thing. (source)
So nope — don’t try to turn your pup into a little pescatarian without professional help.
What are signs of fish allergy in dogs?
While it’s not super common, some dogs can react to fish. Watch out for:
- Itchy skin, rashes, or constant paw-licking
- Ear infections that keep coming back
- Tummy issues like vomiting, gas, or diarrhea
- Hair loss or bald patches
A study in BMC Veterinary Research even showed some dogs react to cod proteins. (source)
Which fish is best to feed dogs?
Vet-approved top picks:
- Salmon (wild, not farmed)
- Sardines (small, low mercury, easy to digest)
- Herring and whitefish
- Cod, flounder (mild flavor, dog-friendly)
PetMD also gives these a green light. (source)
How to cook fish for dogs
Cooking for dogs is easy:
- Bake, steam, or poach fish — keep it plain.
- Remove all bones, fins, and skin.
- Skip spices, oils, or sauces (especially garlic and onion).
- If using frozen fish, thaw and cook thoroughly. (source)
Think “simple and boring” — your dog won’t care about seasoning, trust me.
