German Shepherd / Border Collie Mix Puppy

We have a German Shepherd / border collie mix puppy for sale. Both parents used to be police dogs working. He is about eighteen weeks old. He's up-to-date with all his shots. Happy dog, very involved and caring. Growing up with boys. Comes when needed. He is to learn to listen to different orders in the basic school of obedience. He's even mastered some tricks like playing fetch, sitting down, and laying down. He comes with a doggy bed, collar, hardness of the car, leash, collar training and some of the toys he likes, all of which are worth around $150.00 in total. I'd be willing to sell dog house and cage on the side for an extra $200.
