While I don't necessarily agree with using pinch collars for any dog, I can see it being useful for bigger dogs and not causing any problems for bigger dogs because of their size. But for Yorkies, their necks are already fragile enough and they are so small, I definitely don't think it's a good idea. Have you considered clickers or rattling coins or a water bottle spray for Eddie?
Wow, that's pretty dedicated that owners would wear one to test it out, if it's not painful for the larger dogs, then I'd be for the use of them (but only for the larger dogs). You've brought up a good question, alaskayorkie!
