Jeez, Louise.. As a long time dog owner, I suggest you either seek help with your dog training methodology or get rid of the dog. That is not the way to train a dog, period.
If you want to train your dog to stop wetting, defecating in your house, you need to (1) catch him in the act, and (2) make his living space smaller such as using a crate.
If you can catch the dog in the act, then you need to act quickly to spank, scold, and if needed, rub their nose in it...but...you cant do that if you dont catch them in the act, and, you surely cant shove it down their nostrils or throat. They need to associate the negative consequences with the act theyre doing, or its a waste of time.
Crate training forces them to hold it since they wont want to go the bathroom where they live. However, you have to be reasonable and limit the time when theyre puppies to only an hour or two, then up to 4 hrs, then eventually 6-8 hrs. You cant expect a puppy to hold it for 10-14 hrs, thats not realistic. Can you hold your urine, crap for 14 hrs? But the crate s/b small enough that they can turn around in it, but, so so big that they can avoid a mess if they go in there.
Anyway, please... stop doing that stuff to your dog... seek professional help from the Humane society, dog trainers/breeders, friends, etc for training your dog properly...and dont teach your kids to do such things.
