Yes, we are guilty of playing tug a war. According to the vet, this can encourage aggression but we have been teaching our EB on how to let go when he pulls too hard or starts growling.
Oh yes she does. We try to limit it though as she tends to get really rough and has to have to part that you are holding and will sometimes miss and get a hold of your hand.
Yes; we love tug of war. We try to keep in specialized to the toys but my girls will tug on anything they find appealing. Shower curtains, bath mats, towels, their blankets etc. Tug of war is a must in our house.
Brutus has never liked tug of war. I throw it, and then he keeps it away! He's so silly thogh, I'll hold it up in the air, and he will jump up with all four paws off the ground to try to get it I always throw it for him though.
Bazza loves it, we don't like to play it as Bazza would like to be dominant and playing it and losing to him is not a good idea. (Except the kids cannot help themselves no wonder he is the boss of them ! :-) )
