This recipe is all about simple, nutritious ingredients that come together to make a complete and tasty meal for your dog.
- Mackerel fillets – The star of the show! Mackerel is rich in omega-3 fatty acids and protein, which support your dog’s coat, joints, and overall well-being.

Ingredient Notes and Substitutions
There are just a few important things to keep in mind and some easy swaps if you want to mix things up.
- Always use boneless fillets. Fish bones can be sharp and dangerous, posing a choking risk or causing internal damage.
- Be sure to rinse the quinoa thoroughly before cooking. It has a natural coating called saponin that can taste bitter and might irritate your dog’s tummy.
- You can swap the mackerel for other dog-safe fish like salmon or cod. Here’s a handy guide on fish dogs can eat if you want more options.
- Instead of quinoa, try white rice, brown rice, barley, or sorghum. Just note that cooking times may vary depending on the grain.
- Not into peas and carrots? Use green beans or broccoli instead. You can even try a combo!
