Doberman Pet Sitting

Looking for loving pet sitter who is comfortable and preferably experienced with a Doberman. He is 4 years old, very sweet, 98lbs, Due to my school schedule, need him to be let out in my yard to potty and play for about an hour in mornings and then again in afternoon. We can be flexible and could be a 2-3 hour once a day visit to hang and watch bluey and with toys. Or be a two time visit a day. He is crate, leash and potty trained. He is a big boy and can be intimidating if you are not used to big doggies. Certificate of obedience training. So needs playtime and companionship during the day when Im at school.
