Pooping on the Sofa

Sam is a 6 1/2 month old neutered male and was rarely having accidents until a week ago (he would go outside or on his potty pad). Last week we went to my parents house for 4 days, during which he kept going #1 and #2 on the carpet and a large rug (we only have hard flooring at our house). When we got home I knew he might need some refreshing on the correct spots to go, however he has developed a new behavior that seems very bizarre. He has been pooping on the sofa, normal in the morning (he normally goes 2 times in the AM, so he goes once on the potty pad and once on the sofa). My husband spends most evenings on the sofa and often sleeps on it as well. Sam is fairly infatuated with my husband and often spends his evenings hanging out with him on the sofa (I am home all the time with him, but my husband works full time). He is showing some separation anxiety, but not much more than normal (he is normal asleep when he goes to work). Why is my puppy pooping on the sofa and how do we stop him from doing it?
