Hi, my puppy pax seemed to be bouncing off the walls from 6-10 months, I had to take him on many walks a day for him to be mellow. I did a lot of capturing calmness and that helped a lot. Now, when I'm at home or work, he pretty much sleeps 80% of the time. Especially at work, he'll sleep until I call to him to go outside to pee or when it's time to leave. I also work at a horse barn part time and I'm wondering if this is helping to drain his energy? He plays all day with the other dog there, or he follows me. I'm just a worried mother, but he just seems really calm for how young he is... And he's supposedly a Lab/Border Collie! Does this sound normal, or should I be worried?
