You don't have to agree.  You don't have to use it.  Makes no difference to me.

But showing a dog their poo and correcting them combined with rewarding for going poo in the desired location works.  Correcting them ony when you catch them in the act can teach them that it's OK to poo in the house when no one is watching. 

I have 2 dogs - same age, same breed, obtained at the same time.  One was easily house trained by simply rewarding him when he went in the desired location.  The other was much harder to train. 

If using a positive only method works for you then great.  But there is nothing wrong with showing and correcting even hours after the fact as long as it's combined with rewarding for going in the correct location.

The argument for not showing and correcting is that it can lead to them eating their poo, which can happen if the showing and correcting isn't combined with rewarding and praise when they go in the correct location. 

And no one rubs their nose in it.  That's simply gross.  But showing them their poo is perfectly OK.  Heck, as soon as they drop it, they turn around a sniff it.

 

Thanks Hundmutter.  I'll try to remember Dogs aren't little people, although I can't remember ever showing a little person their poo and correcting them. 

I don't care if people agree with me or not.  Showing a dog their poo and correcting them along with rewarding them for correct behavior works with no adverse impact.  You don't have to agree.  But it works.  People can chose not to use the method if they want or they can chose to use it.  Makes no difference to me.  But people who are making the choice need to know the truth.

Now, if all they are doing is correcting and if they start out correcting, then that's bad.  But that's bad training regardless of what is being trained.  The desired behavior has to be taught first.  And if your dog picks it up from there, then great.  But if not, then correcting the undesried behavior is perfectly OK, whether its going to the bath room in the house or jumping up on people.
