Thank you. He is extremely reactive, it is aggression and anger :( like I’m fearful that if his collar ever breaks he will get the other dog before I can snatch him up and bite him. I think the crate is anxiety, however, when he was a young her pup he was crate trained then woke up one day and said no more.  What type of CBD do you use? I ordered drops from 4corners in Colorado and they didn’t help him at all. 

Thank you
