I hope you like YT and visit often. Four months is an adorable age.

Your problem is probably due to his teething. Teething is very painful for some yorkies, while others have little trouble. His gums may be painful and swollen, as well as feverish. Sometimes ice cubes and frozen wash cloths to soothe their gums will help.

If you are feeding something different than the breeder had him on, then that could be part of the problem with his eating.
