Hi. Ive got Alfie a male 2 year old collie who is very very laid back in normal everyday life. We have started entering some agility shows and the problem is that he gets so excited watching the agility he shakes all over, bounces and nothing distracts him.Ive tried treats, turning and walking away, blocking him. watching from a distance and waiting untill there is no one else in the queue but nothing will distract his attention and his excitement.Once in the ring he will do everything but at 100mph. I have noticed towards the end of the day he tires himself out and becomes much more managleble. I was wondering if anyone had any suggestions, I have thought about calming pills but dont know enough about them. Any suggestions please. Thanks
