Is There Any Nutritional Benefit of Tuna for Dogs?

Tuna comes packed in protein along with vitamins, minerals and nutrients your dog needs. Therefore, there’s a lot of benefit to feeding tuna to your furry friend. However, you want to be judicious in how much you feed your dog.

Because the oceans are polluted, there are lots of toxins and poisons dumped into it on a regular basis. This means there’s far too much mercury in tuna than there should be. While a little bit of tuna here and there won’t hurt your dog, if it becomes a regular part of their diet, it will.

Mercury has a tendency to build up in your dog’s body over time. It can cause a host of symptoms including nausea, vomiting, blindness, anxiety and many others. Therefore, be mindfully ginger about how much tuna you feed your dog.

  4. Then, break up the tuna filet with a fork so it’s in little itty bitty pieces. Mix it into the biscuit batter that should form into a dough at this point. If it’s too moist, add a little more flour and when far too dry, include a little more water or lactose-free milk.
  5. Flatten the dough with a rolling pin to about ¼ inch thick.
  6. Take your cookie cutter or a knife and make bite-sized pieces that will be small enough for your dog.
