My Toller retriever has arthritis in her back right leg which is causing a partial collapse of the hock. Noel Fitzpatrick’s practice in Surrey recommended this brace 3 years ago, and it was initially fitted by the vetinary nurses.
If you want a brace to take out of packaging and put straight on, this is not for you. However it comes with excellent adhesive padding, and Velcro strapping that you can add to shape the wrap and provide a good level of support. I would say that without the template initially provided by the first one fitted at the vets, I may well have struggled a bit.
I have attached some photos so you can see the padding I added inside, and the back of the brace showing a criss cross of Velcro to add the shape and support.
I did try the Balto brace as a cheaper option, but this was not suitable at all for my dog. She is too active to wear the brace with the metal splints inside, and without them it is just floppy material.
So I would highly recommended the Therapaw Tarso Flex X wrap if your dog needs support to maintain an active life.
