Chibi is my 3yr old yorkie who has kind of been an only child ( for the last year and a half hes lived with my families lab) but we moved out and now got a new puppy. Mostly he plays with the puppy and they get along great but every now and again he gets possesive with things. Today he had a toy and was growling at the puppy, I tried to distract the pup but she went after him and the toy and I think he bit her- she yelped but I didnt see any wounds. He has never been like this before, I've always taught him to drop things and trade and hes never been possesive like this.I'm very worried about him and my puppy. What do I do???
