Bentley is my 15-year-old schnauzer- dachshund that I rescued 13 years ago. He has arthritis in his hips and poor strength. He slips on my vinyl flooring and if he is sitting down he can’t even get up. These boots fit great.  I did measure before I bought them. Only problem is it was warm enough today that the snow was melting and they got soaking wet so I think I’m gonna have to take them on and off every time he comes in and out. I guess I’ll have to dry his feet to make sure his feet aren’t wet when I put them on him. When I first put them on him he walked normal and didn’t even act like they were on. He wore them most of the day today and they stayed put. These are nice boots compared to the ones in the stores. Thank you! ♥️🐶
