my toby will bite and has. i have to watch him CONSTANTLY.he does not like anyone touching his mouth.i had him nuetered because of this, did not want to pass this along.
so i live with it but it is chore i dont enjoy.
my vet said SPROUL I AM SEEING MORE LABS COMING IN WITH AGGRESSION.
i bought toby from top breeder too.
but that could be said for other breeds too.i seen a few GSP that bite.
