These boots are ideal where dogs are working on hard or stony ground. The unique feature of the lace-up boot is the open design which allows the paw to breathe. The Lace-up boot incorporates holes in the toe to locate over the two centre nails of the paw. This, along with the lace-up feature, ensures these boots stay in place in all conditions and work activities your dog may encounter. Sold as a pair, medium-size only.
