Cooper is 7 months and he is doing the same thing lately. And we have noticed the more you try to inhibit him from doing it he comes back with a vengence. Like he thinks we want to play or fight. I have been using time out... with minor very minor improvement. that is short lived. I have tried replacing my hands with toys. which doesn't seem to work all that well.
I have started to turn away and get up and get away from him, along with putting him in a time out.
I am at my witts end partially because my family does not support me and so there is no consistancy
I think that is the WHOLE KEY RIGHT THERE. When I have been able to devote a whole day to him and his behaviors I see progress but then I have a day when I have to be gone and we go back 4 steps.
THen all I hear is "Mom Your &$%# dog this and your #&^%@ dog that"
US Yorkie moms have to stick together.
