I just had to ask one question.. Did the neurologist do a MRI?? if not how do they know that it is going to perment?? is it because of the way the disc slipped.. I think water therapy would be great for Bentley but you would have to make sure you get the okay from your docs.
Also please check out Babybear's dogster page. There is a lot of information on there..
http://www.dogster.com/dogs/136060 you will see water therapy, Me teaching to use his wheelchair, Acupuncture and many other things.. So please take a moment if you have time to see what i do for Babybear.. He was paralyzed from the neck down he at the beginning could not move anything for a long time. But with the therapies and his acupuncture he started to do things and then when he got the RIGHT cart( I say this because you can go to many cart dealers or call them but it doesn't mean you will get what you need.. I learned this the hard way) Since having the right cart he can walk with out me holding him.. This is a great accomplishment for Babybear and I know a cart simular to babybear's would be great for Bentley.. Bentley would need a rear wheel cart but
http://www.Eddieswheels.comis the place to get it.. They stand behind thier work for the life of the dog.. Not many do that if any.. Please check into Babybear's page and call Leslie at Eddies and chat with her on your options.. she is wonderful..
