Charlie Dog is all better!
Yesterday I took him into the vet and they said that they believe it is a genetic early onset of arthritis. Charlie is a rescue. He was rescued from a puppy mill. His genetics are not the greatest. They have given us an anti-inflammatory and he is his waggy, happy self today. Judging by his behaviour he has been in pain for quite some time and we did not know. The unfortunate thing is that he will probably require medication for the rest of his days but he is comfortable and that is what matters. He is back to being our happy guy and we are glad for it.
