Hi i am wondering if anyone has some suggestions on dealing with dominating behaviour. My boy Denzil has displayed horrible domination at his mate Jasper. I have just witnessed some horrible sparring to the point Jasper was frozen stiff scared of Denzil who kept beating up on him. I separated them & had to give Denzil some rescue remedy to calm down. What started it was Denzil was getting his nails trimmed & beacause he was not happy about it he took to Jasper. As this was traumatic for Jasper i don't want to see this behaviour again & appreciate any help.
