The link provided clearly shows sound & vibration collars in the small dog (yorkie) size. I don't think this is any worse than those on here that advocate spraying water right in a dog's face as a correction method. And isn't clicker training all about sound training....and again, plenty of advocates for that here on YT.
Anyone that knows Trish personally (as a few of use here on YT do) and have been welcomed into her home and seen first hand her interact with Nali and the luxury in which her pup lives wouldn't ever question her ownership of any dog....or should I now say dogs??? As she's recently welcomed another yorkie into her home
Trish, I'm so looking forward to meeting Barbie tomorrow in person...and giving sweet Nali a snuggle too
