Often times a male yorkie will attach itself to a female in the house, and a female yorkie to a male in the house. I did not know this myself , and brought home my Suzi. She is a little sweetheart. However, when my brother comes over, she totally forgets all abot me, and adores him , it's all about my brother. So I guess their is a bit of truth in this.
If i were you, I would start praising your little guy all the time with everything positive. No more physical punishment. Give hime lots of safe treats, spend time playing with him, try winning back his trust. This will take time. But, it will happen. You do the feeding. Talk inn a softer voice, calmer voice. Sit on the floor. Your going to need to really have to undo the fear in your dog . Your going to need to try to have him trust you again. Take it slow, and with great patience, and at your dogs level, let him do all the moves, don't force him to come to you or anything or touch him . All the touching you to to your yorkie from now on has to be gentle , petting, soothing and nice. No more rough, or spanking him , no more of that. it does not work on these tiny breeds. They feel it , and it just terrifies them, Yorkies are very skiddish , and tings like that make them scared very fast .I hope you can undo the emotional damage.
