I know there are a few vet/vet assistant's here, so i was wondering... My dog has been diagnosed with luxating patella in both hind knees by three seperate vets. They have given me varying degrees of the severity of it. all have said she will most likely need surgery on both knees in the future. Maya is also overweight. I have had her on diet food for a few months with absolutely no results whatsoever. She is currently on Wellness. I had been taking her for a walk every night for about 2 1/2 weeks prior to Christmas, until her kneecap begin slipping again. I should say that previously her kneecap slipped out a total of one time when I took her to the vet for the initial diagnosis. So it has not happened since then up until now. It began to happen for three days in a row, I of course took her to the vet and they told me to let her rest. So no more walks. It happened for another two days, I went away for 11 days, and have been told by DH's mom that it happened the first day she was there and not again. My problem is that she needs to lose weight to help her knees. Okay so...I've been researching on the internet and honestly I'm not able to find alot of information. But I hear that canine physical therapy can work wonders...which is usually swimming. So my bright idea is...would it be a good idea to put Maya in my bathtub, and let her tread water? I canot find a place that does this where I live, even though we have the same course at the university here. Also, she will most likely have arthritis in the future, should I be putting her on a Glucosamine/Chondroitin supplement now? I know I need to go and talk to an orthopaedic surgeon about this...but in the meantime any information would be appreciated.
