I use both and my dogs go to both yearly. My one dog had severe allergies and the traditional treatments were NOT working, and were doing more harm than good. I have always fed Holistic and now Raw food and the improvements were dramatic and amazing, so at recommendations of a very knowledgeable dog person I started to take my dogs to a holistic vet. Most Holistic vets have you keep a traditional vet as well, so my dog to go to both. My dog that had allergy problems was successful treated by the holistic vet. There are no side effects to the natural treatment and thank God NO steroids. All i know for sure is nothing the regular vets did worked and I am talking 3 years and about $3,000 in treatment with no success. It was months and a few hundred dollars with natural treatments and my dog is allergy free and I am not killing him with drugs. Also the Holistic vets can help you with all natural flea tick treatments so that you do not have to use the common toxic flea killers. I have for years used natural flea treatment and never had one flea on my dogs. I have learned so much from the Holistic Vet and my dogs are healthier. Like I said I still have the traditional vet as well, which at least my holistic vet requires. But from factual experience, I think Holistic Treatments and Vets are great and worth it. My dogs are healthier and happier and the regular vet did not get them there.
