Jak sie masz! My name Borat. Why dog like pee in tire?

Because dog smart and knows that tire go round and round over a large area of ground thus marking more territory with dog pee than dog can do alone when dog pee on ground only. So dog say - hey, I pee on tire one time, but look at all the ground my pee covers. Pee on tire good for dog. And all the bitchez are in awe of dog who mark large territory with his pee.
