Tuna Fish Biscuits

Tuna is a very lean protein that is chock full of vitamins and minerals. It’s a good source of B3, B6 and B12, folic acid, selenium, and omega-3 fatty acids. Omega-3 fatty acids are particularly beneficial to your dog, because they support joint mobility, improve the skin and coat, and promote heart and kidney health.

Please note that tuna is only healthy for your dog if it has been cooked. (No doggie sushi!) Never, never feed your dog raw tuna.  Certain types of raw fish, including tuna and salmon, can contain a parasite that causes a potentially fatal disease in dogs known as “salmon poisoning.” For your faithful friend, always stick to thoroughly cooked tuna steaks or canned tuna. When it comes to canned tuna, you should opt for light tuna rather than albacore, because light tuna contains a lower level of mercury. And to keep the fat content to a minimum, be sure to choose tuna packed in water rather than oil.

One additional warning: every dog that has tried these treats has gone completely CRAZY over them! Be prepared for lots of whining and begging for more–even from the most finicky eaters.

Tuna Fish Biscuits

Makes about 80 (1-inch) biscuits


1 (5-ounce) can chunk light tuna in water

1 egg

1/2 cup water

1 cup cornmeal, plus more as needed for dusting

1 cup brown rice flour

1/4 cup oat bran


1. Preheat the oven to 350°F.

2. Place the tuna along with all the water and juices into the bowl of a food processor. Process into a puree.

3. Transfer the tuna puree to a bowl, and add the egg and water.

4. Add the cornmeal, rice flour, and oat bran, and stir to combine. Use your hands to knead the mixture into a smooth dough.

5. On a lightly dusted countertop, use a rolling pin to roll the dough out into a sheet about 1/2-inch thick. (This dough is not very flexible, so you won’t be able to roll it out very thinly.) Cut the dough out into pieces using your desired cookie cutter, and arrange the treats on a baking sheet lined with parchment paper.

6. Bake until the treats feel firm to the touch, about 18 minutes. Turn the oven off and allow the biscuits to dry out inside the oven for about 2 hours.


These treats must be stored in the refrigerator.
