LOL Jane, Coke is the opposite, overly friendly! His collar has returned him pretty quick (he's also chipped, and the GSDs are chipped and tattoed). I prefer the brass ID plates because tags always get ripped off. Usually I end up with my dog at home and the tags lost. I've had people call me to say they've found my dog's tags.
Ah ok. I guess I've just never had a naked dog. Lol all my past dogs wore collars 24/7. Her hair is just too pretty to mess up. Maybe ill get a nice leather collar for her to wear when we go places and leave her naked at home then. I have no other reason for a fur saver since I do French ring.
Even if the dog gets a cowlick from a collar, you can wet the hair and brush it back down. Also I don't think regular collars really break hair, unless they aren't being used properly, they just push the hair into a cowlick.
