My friend used one on her aging GSD whose back legs were giving out. It added another year to his life and he was happily chasing his kong. He didn't like it much getting in and out of the wheel chair tough - but once in it, he just raced around like crazy
He also didn't like to have the hind legs in the sling - my friend used some vet wrap on his legs so they wouldn't get sore. You can also buy dog booties for that.
Best wished and good luck!
I also used one for Ozy for the last 1.5 of his life (eddie's wheels). it was great. He had no problem using it, and we took him all over in it. It allowed us to give him the freedom and quality of life he deserved. We donated our cart to Eddie's wheels so they could refurbish it for a GSD in a rescue. They also have some used ones on their site.
i was always surprised how FAST he was in that thing. A few times he got completely away from me tearing after something. Of all the $$$ i spent, the cart was the one thing that I KNEW made a difference in his life.
Albert has degenertive Mylopathy, and Xoe has extreme hip diplasia in her left hip, and is only five. Al's disease seems to be moving slowly, but Xoe's hip seemed to come on fast and out of nowhere. They both happy and in a good state of mind, so I want them to be able to go on walks still without the pain coming on later. I'm deciding on what kind of operation we want to do on Xoe. I'm a little scarred about the surgery, so I'm trying to find out all of the options, like recovery time. Xoe is a working lines dog, and still wants to go, go, go. Do you think I would need two different sizes, as Albert is about 100 lb stocky male and Xoe 85 lbs, female.
