you can leave the harness on all day as long as it is fitted properly. it does make things easier during potty training so you can quickly leash her and go outside.
I have a collar on my 4.5lb yorkie all day long, every day since she was a little pup. the collar is fitted properly and i have NEVER had a problem with her. She is almost 3 years old now. At first i had a collar with a bell on to be able to hear her but now she just has her tags on which make hte same amount of noise.
having a collar or harness on 24/7 is not a bad thing if done properly. If you are the least bit unsure about it then do not leave them on when the pup is unsupervised just to be safe.
