I would highly recommend cold laser treatments. My dogs have had it for a CCL injury (to support healing after surgery), interdigital cysts, and hip dysplasia. The laser treatment is part of ongoing treatment for my guy with HD. His routine includes acupuncture, underwater treadmill, laser and massage and stretching.
I think it was very effective for the interdigital cyst on the other dog.
My HD dog gets it weekly, generally speaking.
