Hi there...I dont use collars on neither of my dogs. For my yorkie I use harness vests and harness dresses that I mostly make myself. If I buy a dress I add a D-ring to it . There are members on here too that sell beautiful harness dresses and vests. The reason I make my own is #1 I add buttons cuz I have found Velcro does not hold up under the pressure of the dog pulling and #2 cuz I line them with satin so they dont cause hair breakage.
