Question Re: Exercise
I make is a point of visiting schools during recess, lots of kids playing, yelling, running, screaming, etc, Of course someone will notice you and lots of kids will run over to pet the pup, I always brought kibble, and had the kids sit and each feed him 1 piece. He learned to approach calmly, it is only dog food, take gently and accept pats and hugs. I have the stablest dog around kids for not living with any. Also go to baseball diamonds, soccer fields, rec centers and walk by the doors, anywhere there are kids.
I would wait for his medicine to be over and him to be feeling well then I would do this, at such a young age I wouldn't worry about exercise, just play lots rolling balls, shaking tug toys, hiding, etc and he will soon be ready for more and longer walks and definitely enroll in puppy kindergarten, where everything taught is positive, no punishment, Enjoy
