We have a super friendly, family friendly 3 year old puppy. Our issue is that if our kids go to sleep she resource guards them. The puppy will join the sleeping kid and then becomes aggressive if someone else comes into the room or even hear steps. Aggressive with growling, barking and standing between the child and me (or whoever comes in). If I go to remove her by the collar she will nip at me. What we do is call her out of the room and offer her a treat if she comes and stops barking. I think we have encouraged this behavior. Our fix to this was to not put her in this situation, the kids rooms would stay close at night, the dog was not allowed in there. However, now if a kid goes to the restroom in the night and leaves their door open, the puppy enviably goes into bed with them and starts guarding them. What should we do? The puppy does not hurt the kids she is guarding, but does scare them because the barking and growling is loud and they are sleeping. I think we can get her to recreate this behavior with a mock sleeping exercise, if that's the way to go? Thank you very much!
