Arthritis can be helped by a certified animal chiropractor. Not every chiropractor is certified by the american vet chiropractic assoc so check.
If the arthritis is in the hind end then your dog will put more wt on the front end and strain the shoulders and neck.
Chiropractic can help with the front end issue as well as improve movement and decrease pain where the arthritis is. Adjustments along with cold laser and rehab exercises that you can do with your dog will help.
Most Vets will not tell you to bring your dog to a animal chiropractor so please check out my webpage at indekchiropractic.com as well as email me at indekchiropractic@gmail.com.
Thanks
