<human>: We have a 4 month old puppy, mom was husky, dad we deduced is half lab the rest rottweiler/German Sheppard. Her name is Tesla. Tesla had made friends with a pair of Shiatsu's named Rolly and Jersey. Jersey is fine and puts Tesla in her place when she tries to play either too rough or he just doesn't want to. Rolly on the other hand is where the problem I'm having comes in. 

Rolly will entice Tesla to play and chew on him just to get her in trouble. Telsa has almost become obsessed with chewing on his neck and ears. Rolly doesn't fight back or tell her to stop but just whimpers almost in a fake manner now just to get us to split them up. When we do he runs right back to her to tempt her again.  Splitting them up we tell Tesla "No, Drop it" but she get fixated on what she's doing. So we have to force her to drop it, then have her sit and praise and treat for listening. She'll be good for a few minutes then resume the game with Rolly. 

Our big worry is that Tesla is going to be a large dog and don't want to risk injury to the littler dog. She already gets fairly rough and shakes and chews on Rolly's ears and neck. I don't want to encourage that behavior but know it's puppy play. 

Tesla usually gets two play sessions most days. One in the AM with the Shiatsu and one in the evening with 2 of her siblings and who think is her sire. So she gets play sessions with both dogs her size and smaller dogs to learn to play with all sizes.

Provide a brief overview of the text.
<bot>: My puppy thinks another dog is her chew toy and will play endlessly chewing on him to a point of being rough or aggressive. The other dog encourages this behavior just to get my puppy in trouble and is too gentle to fight back.
