Hmmm... I have not yet had roosters. Holding him in your arm to assert dominance and get him comfortable being handled seems ok. But capturing him with the dog going crazy on the other side of the see-through fence seemed kind of mean and scary for the rooster. Especially when he needs to show the hens he can protect them. A little warped for me. However, remove the dog from the picture and don’t shove his head down and the rest seems ok. I could probably have a more valid response if I actually had roosters. LOL.
