I recently started a thread about how my puppy becomes a bit of a butt when seeing other dogs on walks. Well two days this past week he was a LOT better. Nothing had changed that I can think of, he just seemed calmer throughout the whole day. Mostly he laid around at home afterwards, but didn't sleep as much as usual those days. Is my puppy becoming an adult? Moving out of the teen phase? He's just over 9 months now, what age did yours begin acting more mature?
(here he is at 9 weeks)
Here's a recent pic of him. He's half Pomeranian, but everyone thinks Chihuahua right away.
