I had a Cocker that blew his spine out. He and his mate lived in and out of the garage. I called him one night for dinner, and he came dragging his rear quarters as fast as he could. After about three days of I.V. Prednisone and antibiotics, he regained his mobility, but never got the bladder control back. He was about 16 years old when he died.
Always have had a dog. You sure get close.
I used to race my Acura NSX a couple of times a year, and my Miniature Rotweiller(4 lb Yorkshire Terrier) was my constant companion. Folks in the car club called him "The Road Warrior." Wife wouldn't ride with me because I drive too fast, so I traveled with the dog. Dog can't jump into the Hummer because of the high road clearance, but if I pick up the keys, he is ready to go.
Ask you vet about Prednisone. It is like the bazooka of anti-inflammatory meds. Might help.
I have never been able to view any of your pictures you post up. Don't know why.
