Dog Sitter Needed - Full-time / Part-time

Harley is my 5-year-old Pit/Boxer mix. He is a very sweet dog, but does have separation anxiety due to his past and is a rescue. He does well with my other 2 dogs but not too well with dogs he is unfamiliar with. We are headed out of town and unfortunately where we will be staying does not allow dogs. He loves to go on walks and will bark and try to chase rabbits and squirrels.
