Effective brush to style dogs, yet he must leave they do .... The two bitches who are deaf, no problem, they love, the third is still young, much less .... I fact as I read in the comments at the time of purchase, I capped the youngest with the brush without the vacuum, then with the vacuum cleaner off, I turn now, and it starts get better in a few days it should be pushed around! This is super handy anyway because hair does fly more around the cap when they go directly into the vacuum cleaner, nickel! I would recommend to a friend!
