You have to establish first your authority as the pack leader then establish the hierarchy between the boys. The older dog who has been there longer gets fed first, petted first etc. Dogs are pack animals and the new pup is trying to assert dominance. You are the authority and you have to set the tone asap, be consistent and meet the defiance/aggression with a loud clap and "No" when you catch him. Eventually he will settle into his place hopefully. Small dogs like Yorkies tend to be territorial over their owners and they all don't like to share. This behavior is natural given the situation. |
