Review (5/5): This was a fantastic purchase. My dog suffers from disc disease
This was a fantastic purchase. My dog suffers from disc disease. His back will bother him from time to time. I used this on him during one of his episodes and it helps immediately. My vet was charging $40 a visit for the same therapy. I am able to do this at home without the stress of a vet visit. I've used it on my own neck and it delivers quite a punch.
