We have a 3yo Beagle. He's well trained, he is walked daily, other than about 4 hours a day someone is always here he gets plenty of attention. He is outside most of the day and I can see him calmly laying in his kennel or on the lawn. When we let him In after dinner though, he will wander around the house sniffing and when I finally make him lay on his bed he will lick and chew his feet or scratch his ears. He won't stop even if we ignore him for half an hour. If I tell him off he will get off his bed and lay elsewhere on the floor and start doing it again. He's clean, he has no fleas or skin conditions. Normally someone will get irritated and put him outside again where he will immediately stop doing it. It's definitely a behavioral issue but I'm at a loss as to what to do about it.
