I will only use harnesses. After having 3 yorkies with Collapsed tracheas I do not want to put any unnecessary pressure on their delicate necks. I lost my last Yorkie, Gracie at 6 1/2 years of age due to complications of .a severely collapsed trachea. I do not even own collars. There are so many great harnesses for them now. Chattiesmom makes great silk ones that are easy to use.JMO |
