Poor Tuff. It never seems to end for him. Surgery after surgery for lump removals and now this. Last summer Tuff had a minor limp with one of his hind legs that dissipated after a few days. I took him to the vet and she did the drawer test on the leg and said there wasn't any slipping(?) so if there was a tear, it was likely very small. So we decided to try management with supplements and such and see how things went. Months later he started doing the tell-tail sitting funny with one leg underneath which again raised my suspicions. Husband was laid off and money was tight so we continued with the management for the time being since he didn't appear to be in any pain and was otherwise unhindered. FFW to about a week ago... Tuff wasn't jumping on the couch anymore, instead he would slowly crawl up one foot at a time. He also stopped jumping up and down on the bed by himself. He would cry for assistance and we would help him, and it was obvious that his hind leg/legs were bothering him. Then 2 days ago he fell... He was walking in the kitchen and his back leg(s) woomp! went under him. So of course I made an appointment for him to see the vet. We're taking him in tomorrow night and I am just praying that is isn't something worse than an acl tear. My heart just breaks looking at him. I hug him and I kiss him in the dent between his eyes and apologize 1000 times for all of the grief he has to endure and all the surgeries he's been put through. My poor little man. Please keep us in your thoughts and pray for a positive outcome.
