Books are helpful, Dyan
I've been working on drop it with Cooper for months but nothing seems to work.
I've made a huge mistake in feeding Max first and giving Max things first. I'm not sure why I started that but I will change it immediately. I always put Max's food bowl down first, while Cooper sits very nicely waiting for his. Max is not very calm when it's feeding time and I've given in to just feeding him. He'll sit, but you can see he's not calm at all. I'll change that at their next meal today.
It helps so much to type everything out and reread it. I see I'm making Max the alpha dog and that could lead to Coop's aggression.
Does anyone have any tips on training drop it? The same goes for when we are playing ball. I literally have to pull the ball from Cooper's teeth to throw it for him. He knows what drop it means but refuses.
