Anton-Caesar

Just something me and my friend were wondering if any other dobies do.

Basically when Caesar is out on the field with other dogs (my mates dogs) when he is chasing them he then tries to grab the other dogs at the rear of the back with his teeth and sort of tries to flick them off balance to make them fall over in order to catch them, he and his sister both do this, particularly to each other, they also end up in a sort of Tosa style scruff grabbing wrestle quite often (only Caes and his sister have these wrestles).

We dont let them scruff wrestle as obviously i dont want him to end up doing it to other dogs when he is bigger and stronger because its quite aggressive they get eachother and roll around in a ball.

Does anyone elses dobie do this? is it a general dobie habit? its something i have never seen in other dogs, particularly the "drag-trip" as we call it, the scruff as i said is the same as what Tosa's do when they use them in Japan its very unusual.
