[Ringo1]

I got it at Pet Smart. For some reason, I thought the collars all sprayed that nasty stuff you burn in the summer to keep the mosquitos away! Citronella. But, as someone pointed out to me, Citron means 'lemon' in French.

The smallest collar that they had is huge on Ringo. So, unless you have a really big Yorkie, I would say it's probably going to be too big.

I haven't used it much at all; since the weather here has gotten so cold, Ringo has not been staying out and barking.

I will say that it did work for Ringo and my neighbors have all commented on how quiet it has been around here of an evening. Ringo is still his old, spunky self, so it didn't traumatize him for life or anything. But I did use it sparingly.
