My 3month old yorkie thinks his wee wee pad is a toy, he shreds it to pieces... how do I get him to understand that this is his place to poop..

You don't, unless you want him to go on the pad for the rest of his life inside. Pads only enforce the habit that its "ok to potty inside". I suggest you not use them at all especially if he isn't grasping the concept of the pad. There's a big difference in teaching a puppy NOT to do something than teaching it to want to do something. If your having problems w/ him going outside make a routine, crate him while your gone (for puppies they shouldn't be in a crate for more than a few hours their bladders haven't developed enough to be able to hold it as long as an adult). Dogs won't eliminate in their own space (most don't any how). Take him outside at regular intervals, if he eliminates, keep taking him to that spot until he gets the idea. Praise him for pottying outside. Try key phrases like "go potty". Make sure he has a way to go out when he needs to. The little guy sounds like he has a lot of energy so spending time outside could do a lot of good. Hope that helps.

I understand to take him outside, but he doesn't have all of his shots yet...
So then what?
:confused:

If you have a backyard, or a small area, where you know he won't be infected he should be fine. Just as long as you don't take him on walks. He's 12 weeks now so he shouldve had all of his shots or just about done w/ them. All besides rabies which is given at 14-16 weeks.

THANKS... going to try that.

I am having the same problem with my yorkie. But my yorkie goes on the pads when we are home , and was going on them when we went to work.We can't crate train him because we don't work near are home.
Now my Yorkie is playing with the pads and it's a mess when I get home!I have know idea why he started doing this.
Did you find anything that worked for you yet?

Let me know!

You didn't give the age, but I am guessing it is still fairly young. Leaving a young puppy in the house all day by itself isn't a good idea. Sometimes there are more problems than others. Until they are 4 months old, puppies need a mid day meal. All day is long even for an adult. If you can't give your puppy a mid day break, try to find somebody that can, a neighbor, a professional dog walker, etc. The solution is to crate the puppy, and give it a mid day break. If you can't do that, there may not be a good solution.

As he matures, he sleeps less and is more active. He may move from his pads to the waste paper basket and maybe the sofa cushions. Most houses have plenty of juicy cords on the floor.

The "shut the puppy in a safe room" is a fallacy. Very few houses even have a
Safe room. How many of us have a room with a hard surfaced floor and nothing
Else? Most rooms have electrical cords to chew if nothing else. In addition
To destroying anything a bored puppy finds to chew, it may choke or have
Intestinal blockage from the pieces. I had a friend that left her dog in a
"safe" room. It ate a hole in the floor covering. The safe rooms fail to
Give the dog the comfort of the enclosed space their instinct requires. Nor
Do they restrict activity as crates do, extending the time the dog can go without relieving itself.

With such difficulties, I often suggest adopting an older dog rather than a puppy. Puppies have special needs and do not fit many lifestyles. I wish I had an easier answer. I guess you could try spraying the pad with Bitter Apple. It might leave the pad too bad tasting to chew, but still attractive to eliminate on.
