Hi everyone, I have been waiting patiently for Zeus to come out of his shell per se. He will be 6 months in 3 days but he still won't play with ANY toy (plush cloth squeaker, plush leather squeaker, tiny squeaker bear, and a tiny rope) I won't buy him any other toys since he won't play with the ones he already has. Though he is becoming more hyper. He will slam into a pouncing position and then sprint in circles so fast he falls over. He will then try to play with 1 of the other dogs by standing up and smack her in the face but she, just like all of them, want nothing to do with him. He has not attempted to chew on anything as if he was teething (he lost his last baby tooth last week as well). He does not show dominance over the other dogs who are females. Just based on what I have read and the other chis I have come encounter with, they all seem really playful and full of energy. Zeus has not and I will lay money down that he couldn't bark to save his life. The only sound he makes is this horrific cry sound when he is left alone while I am at school. I actually think I am lucky I don't have a lil terrorist, but will he open up and become more playful? And are there other changes I should expect?
