This recipe for tuna and sardines biscuits is as easy and quick as the one for liver biscuits we made a few days before. You only need four ingredients and that’s it.
Speaking of ingredients, sardines can be both, fresh and canned. Tuna is preferable as a can, as the fresh tuna has a high content of mercury compared to many other fish.
Tuna, on the other hand, is a lean protein source, rich in many healthy minerals for your dog, including selenium, phosphorous, potassium and magnesium. It is also a good source of vitamins B3, B6, and B12, and contains omega-3 fatty acids.
As you will see below, I do not mention, what type of vegetables should be used. Here you can use carrots, broccoli or those that your pet likes. It is preferable that you add oatmeal flour (DO NOT use another type of flour, since it can be bad for your dog), so they will be more crisp. I didn’t use oatmeal for liver crackers, since I didn’t have it at home at the time. It doesn’t matter if you don’t add it, they will simply stay more like “muffins” than cookies.
As you can see in the photo from Tokyo, I recycled the can of tuna (500g) so it’s great to store these cookies! And it will serve to save others.
Time: 25 min.
Just mix all ingredients with the mixer, put everything in the silicone mold. If you don’t have the silicone mold, use a teaspoon and put a small amount on the baking paper on top of the baking sheet.
