When I was 7, I told my parents I wanted a dog. They said that I could get one when I turned 8, if I took care of the family dog (feeding, grooming, walking, poop-scooping) until then. From my first dog to my third, I have been in charge of all responsibilities, and each dog is better and better behaved. I have dealt with small dogs and large dogs, from Chihuahuas to Great Pyrenees. I do not discriminate based on breed as long as your pup is not aggressive towards me. I do not believe in physical reinforcement of commands and will not hit or kick your dog. As the owner of a dog with high anxiety, I know that some dogs need structure, reassurance, and a firm voice to get them through the day. If your dog has special needs, I am committed to making sure that their schedule is followed. Disclaimer: As a small person (5'2"), I am unable to walk extra-large dog breeds with aggression. I would hate for your dog to pull out of my grasp and get hurt or hurt someone else's baby.
