Rick, I can certain feel for what you are going through right now. Situations like this are almost as tough on the masters as it is our companions. Kudos for you for doing whatever you can.
I just learned this week that my own fishing partner (in my avatar) has a torn ACL and is hobbling around. Trip to the local vet and some X-rays and exam showed the problem. Our vet said he could do the surgery, but that I would have better results to take her about an hour away to a surgeon who is much more experienced. I do thank my vet for such honesty. We also took X-rays of the hips and there is only mild changes, so the hips are still in good shape. This also is good news.
I contacted this other VET and was fortunate to get in January 8 for surgery. It's gonna cost me about $2,000 give or take, for this surgery. With her hips still in good shape, there was no question as to whether to put down this much money or not. She's got too many fishing trips left in her - she's looking forward to Lakair this coming June.
My best to Jack and hope the surgery goes well and Jack will be back on his feet in good time. If you would, please keep us updated on Jack's progress. I, for one, am very interested to hear what we may also have to go through following the surgery and recovery.
