There is a place I buy a lot of my natural stuff at called HerbMart. I only tell you this because they have business cards for many other holistic, natural practioners, vets included. I go to the one in Plano area but I know they have other locations that might be closer to you. You could call them and tell them you are looking for a holistic vet and ask if they have any business cards available they could give you the name and number of. The phone number for the one in Plano is 972-758-1805...oh here is a e-mail address also
www.herbmarttx.com I have never used that, but they might be able to help you. I have also seen a holistic vet...I believe in Carrollton, can't remember exactly where. I also need to switch to a holistic vet my old little dog. I go to an Herbalist for health problems my M.D.s had worked on for years and couldn't help and he also suggested something to keep my little doggier from throwing up, it worked as well for him as the stuff he has me on. Good Luck and if you find someone you are happy with please post their name and number. I'll do the same.
Best of Luck
