That. Truely is. Amazing. But really, can you only try to clean it up

Aww poor dog

sorry but i LOLed

Stupid trainer. Scaring a puppy (or any pet for that matter) is NOT the way to train it. I found the best way is to speak NO (not necessarily yell) very loudly and clap your hands together loud enough to startle the puppy, it worked for my dog. Seriously I hope u didn't pay too much for this trainer as they are obviously an idiot and it makes me wonder where they got their training.

I do that to my dog and he plays with it..

That trainer doesn't know what they're talking about.

Nothing I've learned about animal behavior leads me to believe that fear aversion training is helpful to dogs. You need a new trainer.

when my puppy did that all u had to do was yell no and spank em (not hard but not to soft either)

That trainer doesn't sound very smart. You don't ever want to strike fear in a young puppy. All you have to do (and it takes repetition) is when you catch them potty-ing inside, give them a firm "NO" or "UH-UH!" (don't use their name negatively - a puppy should associate having its name called as a positive thing) pick them up, rush them outside to the designated potty spot, then they will finish their business there. Once they're done, tell them "Good job!" in a happy voice, use a clicker (if you have one), and reward them with a treat. They will learn in no time. I know this because I worked at a pet store, have owned dogs my entire life, and I currently own three dogs, all of whom I've raised since they were puppies. This method does work. :)

That's a stupid idea, it just scares them even more. Let them out about 15 minutes after eating, if they seem to be sniffing around then they need to go out and if an accident happens give them a firm "no".
