Rank, alpha, whatever is real I've been doing it long before tv shows if you have to fight your dog to cut it's nails or your kids can't climb over your dog or touch their food, treats you can't say your in control or kids are safe with the dog. Corrections have there place and limitations they can make a dog do what you want but they are not going to make your dog safe with kids but it will tolarate them, it can encourage as much fight as the heavy handed alpha roll your thinking of wolves and trainers keep a pack in place with hundreds of mild and harsh corrections teaching them along the way what they can get away with and getting your dog to laydown and submit should be easy for any trainer if you raised the dog my 2.5 and 5.5 year old can from dog of only working stock one of the oldest still working cattle/catch/guard dogs around with lots of fight, prey and everything else. If you didn't raise the dog it would be more of a challenge and needs a trust level before you teach it to laydown and accept your dominance and your kids by just holding them with as little energy as posible but once it does it will work for you better and be safe it needs to be done regular my first rottie gave me a growl once when she was 4.5 when I was to cut her nails for the first time in a long time I reminded her I was boss and cut her nails. Whatelse are you going to do? back off try another day mabye If you go to the vet for some procedure your dog is going to submit one way or another how long it takes is up to your leadership I submited hundreds of different dogs at a clinic you can't do your job otherwise. And wild wolves are much more agressive competing for food and rank only the best two can mate the rest don't, they are only at the top for a few years before someone else takes over and changes the blood. I have lots of video of wolves fighting it happens all the time. Caged animals feed regular may pace and such but are usually much tamer then wild ones fighting for their life everday.
