I've never had dogs other than shepherds, except for briefly having a golden retriever rescue. The guy who rules the household and bosses my two GSDs around is a black male cat who weighs all of 9.5 lbs.!One dog at a time here. Right now, that's Mr B. He's a nine year old chocolate lab. He doesn't care who's in charge as long as someone throws a ball for him. When Miss Cat was around, she was the queen - all 8 pounds of her. Mr B would lie on his back at a respectful distance with all four paws in the air whenever we gave Miss Cat the attention she knew she deserved.
