I am looking for an overnight sitter for my 1-year-old Giant Schnauzer from August 20 through August 26. He is a large, energetic puppy (about 80 lbs) who needs regular walks, feeding, and playtime. He is friendly and still young, so someone comfortable with large breeds is important. I will be away babysitting my grandson and want to make sure he is well cared for and gets attention while I am gone. Please let me know your availability and experience with large dogs
