We have adopted a tripawd that had some sort of trauma post birth resulting in a below the knee, just above the ankle (?) amputation. This was done prior to us adopting her and her stump had fully healed when we got her. She is a 4 month old border collie mix and is very active per the breed. Since the stump is so long compared to most, she is using it to walk and run on and has developed road rash that tears open and bleeds every time she plays outside. We are in consultation with vets and a prosthetist, but since she is so young, we don't have a plan to adapt anything until she is over a year old and mostly done growing. My concern is protecting the stump in the meantime, since she uses it fully as a 4th leg. Does anyone have any ideas or tried and true solutions for protecting the stump. We are thinking some kind of boot/ knee brace harness combo, but hesitate to buy all these products without more info.
