I was steered in this direction by a breeder that I was suppose to get a pup from and it is really a nice harness that is made especially for Yorkies because of the Trachea issues. The webpage is udog.com. I wish they came in more designs, but they are really well made! I like the Puppia soft harness but it still pulls up a bit on the Trachea if it is a bit loose so I use the udog harness. Good luck.
