High protein dog food is a lot more appropriate for dogs than feeding your dogs grains. No matter how you decide to dress your dog, they are avid meat eaters and their digestive system is not "designed" to handle grains.
You can very easily make your own high protein dog food. And there are numerous types of proteins that you can use to make your dog food more nutritious.
The nice thing about making your own dog food, is that you are in control of what goes into your pet's food. You will be able to purchase high quality ingredients such as organic, sustainable, free range, and grass fed proteins which will give your dog the most nutrition.
Other ingredients you can choose to add to your dog's diet would be
probiotics like yogurt, raw cheese, and cultured vegetables (not too salty though).
This is a great and simple way to make a high protein dog food. Make a raw meatloaf and put single serving portions into small freezer bags or freezer safe containers.
Buy hamburger in bulk or hamburger that is on sale to save yourself a buck or two. You could even try mixing different types of hamburger to get a different nutritional and fat profile.
That way you will have a "ready" supply of raw meat to use for your meals or to give them as a treat. It's also a great way to supplement dry dog food to give your dog more protein.
However, I would alternate this method with using fresh raw organic and grass fed meats to make sure your pet gets the most nutrition (freezing will destroy certain nutrients). Although, freezing will help to make "questionable" meats more safe by killing certain parasites.
If you want to use your dehydrator to make dog jerky treats, just follow the manufacturer's instructions for making jerky.
Your dog will probably need some sort of raw meaty bone to chew on for essential minerals like calcium. Bone meal and cooked bones seem to create problems for dogs - especially from swallowing an "undigestible" bone.
Your dog could end up in the emergency room from consuming cooked bones that are very sharp. You also want to make sure that it's an "appropriately sized" raw dog bone.
You should also add in some organic vegetables to your dog's meals to help give your dog additional nutrients.
Just remember that high protein dog food will need to be balanced with enough healthy fats, vitamins, and minerals.
