Review (5/5): Works good
I tested this out on my pugs the day it arrived. I first tested to make sure they didn't fight me too much when I stuck their feet inside of the cup. They didn't. So, I filled with warm water, stuck their foot inside, turned the cup, then pulled their feet out to dry.
Seemed to work good. I just want to be able to rinse their feet of any dirt, sand, pebbles, or anything else that gets stuck in their pads.
I like that it has a small handle so I can hook it up near the back door.
