Our dog Buddy does have some strange doghabits. After sharing his companionship for 10+ years, I suspect that he knows exactly what makes me tick, but some of his behaviors are still a book with seven seals to me. This is one of them: he will suddenly turn on his back and get into a weird, convoluted posture and stare up at us.
It took me a while to figure out this is simply attention seeking. Buddy will do anything to get attention, and groveling is no issue for him. Doghabits! He invites me (or any random visitor, or any unknown lady in the street for that matter) to rub his chest and belly. Scarily enough, he bares his jaws and teeth at the same time, making him look like a little devil… and scaring most innocent bystanders away. The latter are in many cases already confused by his spread-out hind legs, offering a full view on his private parts (of which two essentials are missing since his castration).
The Mysterious Ways of the Labrador
And he is inseparable from his tennis balls. I have to buy new ones regularly, since although Buddy loves them intimately, he loses (and forgets) them as quickly as they drop from his jowls. Labradors are retrievers, and thus having something in their mouth (a ball, a stick, a piece of cloth) is apparently highly comforting. Sometimes he shares his bed with three tennis balls and a deflated basket ball.
