Keila is 9 months and 2 weeks old. She has been a PERFECT pup. However, i feel like she is hitting her terrible 2's (if there is such a thing for dogs). Starting yesterday she has been running from window to window howling and barking at her own relfection as if a burguar was trying to break in. At first it was cute, not it is annoying. she is not listening to any of my commands. She has been chewing on stuffed animals that never interested her befor. and she knows better than to chew on stuffed animals. She has tons of her own chew toys to chew on. She has learned to climb our chain link fence. And she has started jumping up on people which she doesnt normally do. I really dont know wha is going on. She is normally so laid back and well behaved. Do puppys go through a terrible two stage? Help.
