About Us - History

R. Dean Meyer DVMI have been a veterinarian for over 30 years. During those years I have had a great interest and involvement in nutrition and how it affects the health and well being of the animal. In my veterinary practice, I was seeing health problems in dogs that I was convinced would have been prevented by the right nutrition.

When the ancestors of the modern day dog were in the wild, they would kill an animal and eat the digestive tract contents. This is where the dog received its vegetables, B vitamins, probiotics and digestive enzymes. Modern day commercially processed dog food is extruded to add palatability and stability, but it is the heat of the extrusion process (the making of kibble) that destroys those same B-vitamins, probiotics and digestive enzymes. It doesn’t take a rocket scientist or even a veterinarian like me to realize there are benefits to supplementation.

Doctor’s Choice developed Fido-Vite because there was no product on the market that fit the needs to deal with the nutrition problems I was seeing. Fido-Vite is the best and most complete complement to commercial dog food available. Fido-Vite is also an excellent complement to raw food or barf diets. Fido-Vite comes in a palatable meal form so all the enzymes, B-vitamins and probiotics added to the product are available to elevate the dog’s health. No matter how good a product looks, it can’t help the dog if they won’t consume it. Backed up with solid research, Being a veterinarian, I can’t stress enough the importance of intestinal health to the overall health of the dog. That’s why at Doctor’s Choice, we say “Improving Health… From the Inside Out”.

I have enjoyed seeing the overall health benefits in dogs using Fido-Vite. My own Labrador Retrievers and Corgi dogs have had large healthy litters of puppies long after most bitches would be considered done producing. My wife Wendy, daughter Nicole and I have really enjoyed raising these dogs and seeing the health benefits and longevity from Fido-Vite.
