Absolutely love this product. Ajax has had a rear wheelchair for degenerative myelopathy from K9 Carts for a while but suddenly lost a lot of strength in his front legs following a big seizure. The team at K9 Carts was amazing and helped me through the process of measuring and answered all of my questions. They even made sure to include the extra long belly band per my request (he has an extremely long torso). Setup was so simple. I was initially worried about how difficult it might be to add the front support to the existing rear wheels but I had it ready to go in about 15 minutes. He's a big boy so it does take two people to lift him in, but once he's in it's the easiest walk we've had in years! He feels much more confident walking around because he knows he can't stumble and faceplant. You can tell how proud he feels by looking at his expression while he's in it. We talk to him a lot and so we use the phrase "wide turn" to remind him when he's going to need to make tight corners and he's adapted so quickly. We live in an apartment building and he's become a pro at backing himself out of the elevator and through tight spaces. We absolutely love it and highly recommend it. For anyone with a big dog that needs assistance walking, this is much better than throwing out your back while trying to use a sling!
