I am on the opposite side. I too used to believe that was the way to go. After some research I believe that can actually cause food aggression.
I fully expect to be able to take anything away from my dogs bowl/mouth at any time also. I don't tolerate resource guarding etc. but I go about it differently.
I believe in feeding the dog and letting them eat in peace. My dog must sit and wait for me to release her before she can eat. And then I close the crate and she is left to eat in peace. She came to me highly possessive with the start of food aggression. I was able to fix it and she's great now. But had I done the old school methods of messing with her or her food while she was eating I am positive I would have created a food aggressive adult dog.
In my eyes its simple- giving a dog their food and then start messing with them or the food gives the dog reason to think "these people keep coming for my food! I need to protect myself" vs. a dog who has rules and boundaries and training and is made to sit and all that before eating but left alone to eat develops no reason to believe he needs to guard anything from me. Responsible and legitimate dog trainers and behaviorists all agree that trying to prevent food aggression by taking away and giving back food, rubbing hands in it while they are eating etc. is a quick way to make a dog FA not prevent it.
