This is the standard harness (roman harness/roman harness) from Pro4Paws. You can take regular walks here and use it as a harness. But we also use this harness to attach, for example, the hip brace, knee brace.... An extra D-ring ensures that you can easily attach the different braces.
Important with this harness is that there is a (strap) attachment over the neck/neck and a (strap) attachment just behind the legs.
Because the strap has clips on both sides just behind the legs, you can easily put on the harness, even with a dog that has difficulty standing on one front leg. This is especially very pleasant for dogs that have osteoarthritis on the wrist and/or elbow joint or dogs that only have one front leg left.
