I used this on our 2 frenchies Bear & Daisy. Daisy wasn't too fussed but she is always subservient to Bear, the boss-man in their pack. Bear was mesmerised once I let them sniff it first (we use a 'sniff' command so they don't bite what we're showing them). He laid their and rolled on his back then back to his front for me to do his whole body and kept coming back for more. The hair did come off but didn't stick to the brush like in your video. I didn't think it was very much hair from what I could see on the brush, until I actually put my glasses on later in the day and realised I now had a fur covered rug where I'd groomed them! Big vacuum needed - stat! Next time I'll be doing it outside and will be taking it in their shower first too. I'm so glad I also bought one for my daughter's Frenchie Zeus. Well worth the money, best brush for a frenchie and I've bought at lest 5 before!
