Well guys i have a black&tan GSD and this thought's of having a new dog in about 2 more years always cross my mind.
i like tugging with my dogs and i like protection sports so my options are Working line gsd or Belgian malinois
i saw litters of WL GSD And malinois, the malinois litters presented very high
drive much more than the gsd litters.(of course you should pick the right puppy for you and not every malinois are working dog's same as gsd's)
my dog has a very good drive for SL gsd but i think that malinois show's true will to bite and to work more than gsd's, that's what i saw when i tugged with my friend's malinois and lifted him up to the air with the bite tug where my dog stopped holding after being 1 inch higher from the ground.
id like to hear more opinions from you guys
