Piper and her New Doorway Blockers

So, yesterday was pretty much the same. Piper wasn't happy that both of the doorways were blocked so she could not go potty in other rooms, and had to say in the family/kitchen area. We had looked at buying gates, but they were so expensive, and we were already buying so much stuff!
Too funny - This morning (after we had been out twice), she went to the blocked doorway in the kitchen and started whimpering. She was telling me she wanted to go poo on the living room carpet!!! Is that too funny/sad, or what???!!! I promptly shook the bell on the door and said potty, and we went outside. Most times she won't go outside unless I go with her, so I have to walk out in the grass before I can sit and wait for her. For some reason, she will pee outside, but won't go poo, so I get walk her around the yard, Then she will go... but not all the time; she saves that for indoors! lol

This is the doorway from the kitchen to the hall way down to the computer room and bedrooms. (Thanks goodness that the bedrooms have a door!) Here's Piper Pouting... :)

The contraption I figured out to use is my container of gift wrap paper, and a chair to hold it from falling.
A lot of good that did! She peed on my kitchen rug, tried to pee on carpet in family room in corner, but I caught her! Since she is getting to run around with me in the computer room and hall way, she pooped & peed at 2 of the doorways. Of course, me - instead of watching her every second, I was on here - the computer! POO!

This is the second door blocker which I, again, cleverly thought to use (lol), since it's HUGE! I used her Very Large Kennel (I hope she doesn't grow that tall!!!!). The pet store said this was the one to get for a Boxer. UGH.... Please... Please.... Please..... don't grow that big!!!! This blocks the doorway from the family room to the front living area.

The pillow on top I bought cuz it's soooo cute! I picked Piper up and lay her on top of the pillow with a chew toy, and she stayed there for a mili-second, then jumped off to sniff out another place to go potty in the house. :(

Today, I put the puppy pee pads to try again. This time, I put it in the kitchen and taped it down (I know.. I know... I didn't know it had Tape on it before!); so, when I went to the kitchen to check on her, she had torn it to shreds!!

What is it about these puppy pads that is supposed to get them to pee on them, but instead, she tears it up? I suppose that this, plus numerous other questions will be answered once we get to take her to PetsMart for training class. We cannot take her there until she gets all her shots, and she can't get all her shots until she's a certain age. Our appointment with the vet is 2 weeks from now. I never had a problem this huge with training our other dogs! Of course, they were not pure bred. I'm assuming that is the problem? Who knows.

More on the THE SUPER DESTRUCTIVE PIPER saga when I return.
