How do you stop a dog from begging for food?

My 5-month-old puppy begs for our food CONSTANTLY. We do not under-feed him, as we have consulted our vet and he is growing like a weed. We have NEVER fed him from the table, nor ever given him our food for any reason. He begs whether we're preparing, cooking, or eating our meals. He barks and whines continuously for the entire duration our food is outside of the fridge. Between preparing, cooking, and eating our meals, this can last upwards of 2 hours with no relief. What have we done wrong? What can we do to train him out of this? We've consulted professionals to no avail. I've tried absolutely EVERYTHING I've been able find online. Is there something I'm missing?How do you stop a dog from begging for food?
You should try punishing him the moment he tries begging. It'll take time, but he'll finally get it.How do you stop a dog from begging for food?
Do you have kids that drop food by accident? Do they sneak him food when you aren't looking? I'm willing to bet it's one of those two things.



Put the dog out of the kitchen.
have u tried feeding him when you are about to eat that way it wont bug u?i had the same problem with my dog before but when it did that we let it go outside dogs do learn so eventually they will stop so they wouldnt have to go out
Put him in a cage where he cant see you. And only take him out of the cage if he is quite.
Squirt him with a water pistol when he does it.
punish your dog when he begs for food, from time to time, it will stop begging.
stop feeding it when it begs, and put it in another room for a while when you eat..

someone feeds him from the table. face it.

also it might be, it is not getting good dog food, or not as much as it needs.
