My service dog and I are out and about a good bit, and she does REALLY well in Ruffwear boots. Make sure you get some of their socks for them. They really help with the fit of the boot. Neopaws are great as well. I don’t like the Muttluks. We’ve had really bad luck with those.
Mandi, my SD, wears the Ruffwear boots out working, to the barn, on hikes, bikejoring/skijoring, etc. They’ve held up really well to everything. And they don’t come off like most other boots we’ve tried. They are a bit pricey, but worth it if you’re going to be using them consistently.
