Last night when we returned from play day, the pups were exhausted. My hubby got in the shower and me and pups all hopped in bed. Well, Sam was in my hubby's spot. When he went to move Sam from his spot, Sam growled at him. Well, it became a stand off and finally Sam got off the bed and my hubby got in. Anyway, he has never exhibited this behavior before but often does get in hubby's spot and he has to move him. Normally, he just acts silly when we move him but not this time. I know he was completely exhausted from the play day. Once hubby was settled in, we allowed him back up but at the foot of the bed and he was asleep in a matter of minutes. Any suggestions to avoid a reoccurrence? We really don't mind them sleeping with us but they need to know their place for sure...I know this exhibits him trying to establish a higher rank in the pack so I want to make sure he knows his place.
