Teagan pretty much stayed the same. Other than she got a lot bossier, less people and dog tolerant. She is still as confident, and playful as she was as a puppy. Her prey drive did grow as she matured though. As a pup she played a lot with small rodents. The whole catch, injure, let go again, wash, rinse, repeat.
Now she just grabs and shakes and they die. She is all business now.
I predict Panzer will stay the same, although he is going to mature up a lot and get a lot more serious. His people and dog tolerances will probably change. He will get more protective and alert. He might go through a few small fear stages, which is normal with the breed. Boerboels are a very slow maturing breed.
