Natural DIY Tuna Fish And Coconut Dog Treats: Easy, Homemade, Gluten-Free Biscuits



Finding natural, wholesome dog treats, that don't break the bank, is challenging. 
So many treats at the store contain ingredients I've never heard of, which is worrying. 
We made these gluten-free, healthy, and natural dog biscuits that our pooches love!
I've used ingredients most of us have around, and you can easily substitute for things you do have. If you don't have coconut flour, you can add extra oats, and if you choose not to add tuna to your dogs' diet, you can add another type of fish or meat, add a little more water if the consistency is too dry. The ingredients we have used all serve a purpose for our dogs' health.
Oats - A classic carbohydrate for dogs, this energy-boosting food is excellent for dogs who have sensitivities to gluten or wheat. It also contains some nutritional benefits that can help keep your dogs' skin and coat looking healthy.
Coconut Flour - This contains to add some added nutrients and is a great low carb alternative for diabetic dogs. We only used a small amount as it can be challenging to work with as it acts differently than other flours.
Tuna - Although not the best option for dogs due to the mercury level, in small amounts, tuna serves as a source of protein for dogs. It is also something most people have in the pantry. It also has a strong smell, which is very enticing for dogs.
Egg - This helps to bind the whole mixture together. It also adds extra protein to the cookies. 
Coconut Oil - Coconut oil is great for their coat and skin. It is also thought to help with digestion and allergies.
Water - Other than being great for hydrating our dogs, we prefer to use water instead of a dairy alternative as our dogs' struggle to process lactose. It also helps to fill the treats out and keep the costs down without using any nasties.
I also love that they don't need rolling out and cutting, saves the mess and the time. You can alter the size and shape to your dog's preference, the smaller they are, the quicker they'll bake. If your dog loves a crunchier treat, keep them in an extra 5 minutes.
Let us know if you give these a try, and send a picture with your beautiful doggies!
This recipe is designed as a treat for your dog and should not be fed in place of their regular food. Treats should only make up a maximum of 10% of your dogs' daily food intake.
The treat quantity and size can be altered to suit your dog.
Please contact your veterinarian with any questions and before introducing new foods to your dogs' diet.
