I've had the Dr. Noys teddy bear in the medium size for almost 6 months, purchased for my 30 lb sheltie girl.  Our dog is not a "sit down and try to rip apart" kind of dog, but she does love to play tug-o-war!  I usually grip the head while she grabs onto either the squeaking body or one of the limbs, and she hops and pulls and shakes and play-growls until she gets too thirsty to continue.  Hubby and I also play keep-away with the bear, tossing it back and forth so she'll run between us for some exercise (she's not much of a retriever).  Sometimes she'll pick up the bear and bring it over to me to let me know it's time to play, but otherwise she really doesn't play with the bear on her own.  Not the fault of the bear, it's just the way my sheltie is, and I hope it gives you a better idea of how this bear might hold up with your dog.
