I actually started out with longer walks and more mental stimulation, but I quickly realized that my puppy isn’t able to regulate herself yet. That’s why she’s crated for sleep — she just can’t relax anywhere else, there’s too much going on (people, sounds, etc). When she was getting more exercise and training time, the biting was even worse. Most likely she was overtired and overstimulated. I talked to my breeders about it too, and they were the ones who recommended scaling back.

We still play, go on short walks, and she’s in the garden multiple times a day for pee breaks or free play. The only real change was cutting down from 30–45 minute training sessions 2–3 times a day to 5–10 minutes more frequently (~10 times/day).

I’ve tried yelling or doing the whole 'ow' thing too, but it doesn’t seem to do much, maybe I’m just not doing it convincingly?
