I bought these for my 16 and a half year old English Setter, Tosca, because she sometimes slips on tiled floors and also has difficulty regaining her feet after lying down or sitting.
They work really well but are not on all the time. They need to be tight, you will see that one of them has slipped round, and I have a slight worry about restricting blood flow.
They are not needed on concrete or for walks outside.
The only problem is they are a bit difficult to put on and secure as she won’t stand still.
