Ok I got Rex a bully stick( I dont care whats in it lol) Anyway Rex LOVES it and was eating it. My 2 year old went up to him and was trying to touch it and he barked and growled at her. So I went and took it from him he did nothing. Whats up with this? He enever did this before she always mess with him while he is eating and he never did that. YOu think because its his treat or what? How do I correct this?
