I’ve always had doggies since I was a kid. Doggies for me are family. I take care of them like babys. I’m have a lot of pacience with naughty doggies ( more than humans :)). I like to walk a lot so for me its easy to have the time to walk them and I really enjoy it. Don’t be afraid if you have a heavy, strong dog, I workout . I understand it can be difficult to trust your baby with a stranger, I wouldn't hurt a fly, don’t worry you’ll puppy will love me . I have read and study about behavior so nothing for me is new. And most important I’m not doing this because I really have to is because I love it .
