Personally, I use harnesses only when we go out. I just adopted my yorkie Belle in February, but I also have a 1 1/2 yr old shih tzu, Oliver. He was boarded last summer for a week and they left his harness on him the entire time.... when I saw the mats it caused in his coat I wanted to CRY! My poor little boy must have been so uncomfortable.... So not sure about safety, but if you keep her coat long it wouldn't be a good idea IMO |
