When did the teenage phase start for you guys?

Hi everyone! My baby cavapoo is 5 months now and has been losing some of her teeth. She’s an angel most days, and we’ve gotten into a pretty good groove. But I’ve heard smaller dogs mature faster, and I have been dreading her teenage phase hitting.

I was wondering when your cavapoo hit the infamous teenage phase and if it was really as bad as people say?

also here’s a smiling pic of her to brighten up your day :)
