So Reba is starting to be kennel aggressive. She has slept in this kennel every night since she was 6 weeks old and has been perfect until 3 days ago. Now any time one of the cats or my other dog walks by she growls and barks snaps at them she has not gotten to them due to having the kennel door locked shut. But I do not want her getting worse I actually want it to stop. Please any help would be amazing thank you.
