For one, I don't even know why you would post this...you have obviously found nothing on this site supporting this kind of behavior
you're exhibiting. Out of how many members here & how many posts? You do a
cruel thing and there's
possibly a coincidence & you think you've landed on a goldmine of information? I'd hate for someone to come on here intelligently seeking info & not see a logical response to your ridiculous cure for your potty training blues.
I'd love to hear what you did try, and how old your pup is. In all of your extensive research did you discover that a pup isn't even supposed to be sold at 10 weeks? Have you not seen countless times that you do not punish for the accidents but praise for what is done right? I'm also curious about how your poor little puppy made the association between being manhandled into some no doubt disgusting waste & going to her pad.

I also find it to be pretty amazing that out of all of the posts I've read here, all of the books, magazines, websites, T.V. shows they all have examples of potty trained dogs & not one has made a reference to nose rubbing.
Perhaps in your research you did not stumble upon the fact that toy dogs are extremely difficult to potty train, yorkies in particular, but it can be done
humanely? Some catch on right away but others take many months and some are never trained at 100%. That is something that should be considered before purchase.
I hope you're willing to take the time to read up on YT & that is why you joined so you may better the life of your yorkie. There is a plethora of info here on everything from diet, illness, training, pics, you name it. Hopefully you can benefit from the many experienced members here.
And of course,
this is my honest opinion.
