I have a large 110lb American Bulldog Mix. He is a very smart, well trained sweet boy. He is socialized but picky on dogs he gets along with and must have meet and greet first. Loves to walk, play and get human attention. I am in need of occasional check-in or walks when I am away from the house for long periods of time. I want to make sure the sitter and dog are comfortable with each other before a needed event.
