No he wasn't my dog, he belongs to another classmate. He wasn't aggressive either, he simply objected to be held down and stuck with needles. I have been doing squats and lunges but those alone don't feel like they've been helping and because of my lack of stamina I get tired very quickly even doing that. Besides, I've been wanting to learn how to run for a few years now but I didn't know where to start and it all seemed so overwhelming! So I start tomorrow!
