i had this problem between zac and his dad scampi, for years they got on great but then one day zac started attacking scampi it went on for months and i kept on trying to work out why then i worked it out, scampi was top dog and was with me at all times was fed first stroked first everything first b4 the others but a few months b4 this happened zac was really ill and for about 2 months i had to have him with me all the time and hand feed him and he thought i had made him top dog and thats why he was attacking scampi, it wasnt till i thought of that that i realized what was going on so i kind of pushed zac to the side and put him back in his place , it was hard but it worked he saw scampi as top dog again and they got on really well again so maybe your little yorkie wants to be top dog or the dog its attacking wants to be top dog.
