Chase hit 6 months over 2 weeks ago, but I'm still waiting for the crazy. I'm hoping he doesn't really have a bad adolescence. He was such a good, calm puppy for the most part so I may luck out. I have my fingers crossed. The last puppy I had over 10 years ago, when he hit adolescence made me pull my hair out. All housebreaking went out the window, any training was gone (not that I'd gotten him much training as he was a stubborn dog), and he was SUPER destructive.
