Sounds like he is going through a bit of settling in issues. It may take him a little time to understand that this is his forever home. Charley may have some hearing loss due to all the infections. My Clem-does these same things when he gets startled. I've had him for 17yrs and he's very use to his furry buddies disturbing his naps and so far this is the only older aged dog symptom he has.. You will want to brush him often they are shedders and this special time will help the bonding process.
