Great Animal Lover Wanted Immediately

Hello my name is Patty. I am interested in finding pet care for my precious pet. He is very special and has special needs/heart. He can go outside (back yard), but I do not want him to get overly excited (barking), as that increases his heart rate, so I bring him back inside. He can be very affectionate and likes to play. He will be 2yrs old on Valentine's Day! He loves tummy rubs. I need someone with a great deal of experience and who is firm, but calm and encouraging! He is a German Shepherd Rescue. Thanks. Patty
