just keep on it. thats how i get mine to sit for stupid pics like that. lol hell do just about anything for a peice of bacon. my black one knows sit, lay down,shake, they both fetch and retrieve. they are really alot smarter and more perceptive than people give credit for.
but mine are straight killers. they are fast and agile. so i have to be very careful where they go, and unfortunately never ever get to be off the leash in public
they have killed
7 chickens & 2 roosters
2 opossums
10-15 squirrels
2 Rabbits
a cat
and cost me $1000 to repair my X-gf's chiuahuah...
