Animal Chiropractic requires a Chiropractor or Vet to be certified after taking a 215 hour course and exam. There are Chiropractors and Vets that say they are certified but unless u can find them on the American Vet Chiropractic Assoc web site, then they are not.
Chiropractors have been trained over 4 years in post grad work to use their hands in the adjustment of the spine and extremities. A Dr that took a weekend course is NOT trained to do this work and can hurt your animal. The use of instruments or tools to adjust animals is also not taught in the 3 animal chiropractic colleges of which I am an instructor at Options for Animals. These instruments are a sham and you should not be paying for this care.
I travel all over New England making house calls for dogs and barn calls for horses, if u have any questions please contact me at 781-337-1180 or email at indekchiropractic@gmail.com
