Amber, a five year old small yellow labrador, was born with severe hip dysplasia. The muscles in her hind quarters, which have developed from the treatment, are now strong enough to support her in everything she does. – chasing balls, sticks and following trails. Swimming in lakes, running endlessly on the beach. All the normal things that dogs love to do, which used to make her back legs so stiff, are now easy and comfortable for her.
