Awww poor Lui, just wants some friends!!!
J/K
Good job on teaching him No.. I would just stick with that- teach that little booger how he is suppose to act!! Hopefully when his Mom picks him up she will continue to train that nasty behavior.
My good friend has a neutered male, he ALWAYS humps Peanut. ( Peanut is also neutered) it's REALLY annoying... when we walk he will try to hump in, in the store at my house, and his house anywhere.. Peanut is pretty submissive and will just let him. I will ALWAYS correct Todd when he does that, if I'm there Todd is not allowed to behave that way. However my friend will not correct Todd for some reason.. it is really annoying.
I wish people would just teach their dogs how to behave..
