Thanks so much. Who knew so many issues would crop up with such tinys. My last Yorkie was 10 pounds and we loved every bit of him. I made the big mistake of using a harness when he was a puppy but then just using his collar since he walked so nicely - horrible mistake. He wound up with a collapsed trachea. Never do that again. I will see what Lil Sis has and then go from there. Again, good info from YorkieTalk
