Pet Sitter - Now Hiring

Is not comfortable around children or large groups of people. Is not comfortable around other dogs. Lots of barking and extremely agitated when he has to deal with our neighbor dog wanders over through our yard. Pulls on regular leash, choking himself when attached at the collar, does not heal. But does like being on a retractable leash with harness on. He is used to having on a collar that allows him to be within a certain perimeter of our home. We do not have a fence. There are times when he ignores correction from collar and goes beyond boundaries so a fenced yard would be a good thing.
