I can't speak on behalf of my own species, but when I was a veterinary technician I could see the benefits of both acupuncture and cold laser therapy for our canine friends! It was seriously astounding the difference it would make for pets who came in on a regimen. I remember so many dogs who could barely walk and after a few sessions, were so much more spry and energetic.
I could see it in my own dog as well. She has severe hip dysplasia in addition to a myriad of allergies/GI problems. Acupuncture helped
all of her issues tremendously! I have a new job now though, so unfortunately I can't provide that for her anymore
Anyway, based on what i've seen...i'm a supporter!
