Sitter Needed For 1 Dog In Arlington

Seeking a sitter near Arlington for 1 dog. Walking my pet(s) is required. I would need you to provide boarding. We need someone who can provide overnight care. Responsibilities include feeding. My dog is a male Great Dane, not neutered, is 4 yrs but still thinks he is a puppy. He craves attention, loves walks and people. Has limited socialization with other dogs, most other dogs are afraid of him, probably due to size. He is strong and likes to push against you for attention and petting. You have to be firm with him verbally and physically, or he will get his own way. I do not know exact times because I might have to fly back east due to family member's health condition. Just trying to plan ahead to avoid problems.
