Looking for someone's opion...

 My MIL has a male 6 month old Chihuahua, Spanky. And my friend has his sister, Chloe. Both use pee pads and they both started shredding them. My MIL got some of that bitter apple spray and it worked like a charm. Told my friend so she went out and got some and no more shredding of pee pads!

Just lightly mist the pad and see if that works. With Spanky he would grab the edges and start there. So the MIL just sprayed the edges. Like I said it worked for both the pups.

ETA: The MIL doesnt have to spray the pads anymore.

How old is LuLu? Maybe she doesn't need them anymore? When she shreds them is she peeing in the crate? 

EDIT TO ADD: Has anyone seen those new pads they are advertising? They look like a square of grass. I assume they are some sort of plastic. They definitely appear shred proof.

Well, I've tried the bitter apple spray on her leash before and it didn't stop her so I think she doesnt' mind the taste too much.  I will try it on the peepad anyways since it can't make it worse than what she's done to the pads already.  Im thinking she MIGHT dig at them more than chewing it but Im not too sure.  Today is the first time I noticed that she pee'd on her bed....well maybe it was beside the bed and the bed absorbed it to....hard to be 100% sure. Either way, she didn't have a pee pad to use if she wanted to.  She is so stuborn.  She does have  a pee pad in the living room and she doesn't try to shred that one.  It only happens in the cage.  I haven't left her in her crate for long periods of time with me not at home so Im not sure if she would pee in it.  If I leave her I usually put her in the cage. Lulu will be 5 months next week.

Oh...did Spanky and Chloe still pee on the pads even though they smell like bitter apple?  Also, Lulu doesn't shred them at night when I have her in the cage.....it only happens when I leave her

 Yep they still peed on them.

Does she have any toys to play with? You say she's digging at the pee pad not biting it into shreds. Maybe give her a little blanket or towel she could dig/play with?

Yes, Lulu has a blanket on her bed in the cage and I usually put in a bowl of water, couple toys and either a bone or a kong for her to chew on.  I give her the kong frozen with a treat inside when I leave.  It gives me a couple extra minutes before she starts to cry (still have our seperation anxiety problem too)  I will try the bitter apple and cross my fingers.

Oh yeah...she could be shredding it with her teeth AND digging into it...I can see her doing both.  She is my little trouble maker

So, no luck today on the peepad with the bitter apple spray. I got home and she had it in at least 200 pieces.  Im going to see if a different brand of peepad will work better.  Cross my fingers.....

She is so stuborn.  She does have  a pee pad in the living room and she doesn't try to shred that one.  It only happens in the cage.  I haven't left her in her crate for long periods of time with me not at home so Im not sure if she would pee in it.  If I leave her I usually put her in the cage. Lulu will be 5 months next week.

 Are you sure she's stubborn and not just plain bored and distressed at being left alone for almost 10 hours?  I'd presume she isn't interested in shredding the pee pad in your living room because when she has access to it, you're probably home.  Being crated for 10 hours at roughly 20-ish weeks old, you've got a lot of exercising, training, play time you need to do to make up for it.  Presuming you sleep 8 hours, that only leaves 6 hours during your work week for time with your puppy, plus all the regular duties of life.  Any chance you could bring in a dog walker mid-day? 

She might be bored.  I have a few stuffed toys and some chew toys in there with her.  She only started the shredding about 2 weeks ago.  She only did it a couple times and then I was on holidays for a week so she was ok.  Now that Im back at work she's done it everyday.  I used to go home at lunch everyday when I first got her but I thought that her seeing me and getting upset again when I leave would make it worse.  She has even gone with a girlfriend of mine to work during the day to keep her busy.  BUT she's been caught shredding them at work with her too.  I guess I can go home at lunches again hoping that will help.  Hopefully it won't make her seperation anxiety worse.  Im willing to try anything these days. Just got home and she's done it again!  So my idea of a different brand of peepad didn't work.  Im thinking of giving her the computer room to wander during the day.  Then I can put her crate, water, peepad, and toys in it and she'll have room to run.  Does that sound like it might work?  Any thoughts????

 I really think it's counterproductive to subject an already anxious dog to Bitter Apple and force her to remain in her crate with a smell designed to put her off for eight hours.  I would get a Wizdog, so she cannot shred her pee pad, and think about another way to contain her - perhaps a bathroom or safe room with no carpet on the floor.  However, if she truly has separation anxiety she may be destructive of doorways or other things if she can reach them, so try her in the new location when you can be in and out to observe.  Most true SA dogs don't get any real relief from a stuffed Kong - that's because in the first twenty minutes you are gone they are too anxious to eat, and by the time they are relaxed enough, if they ever are, they have already shredded whatever they are going to shred.  Also, your dog is NOT being stubborn or willful - just anxious or bored.  Chewing and shredding are a dog's way of releasing that tension and making themselves feel better.  She may get some benefit out of you doing the training and desensitization techniques in Patricia McConnell's book "I'll Be Home Soon".  If it's boredom, then puzzle toys, more exercise, music or tv on, and lots of training while you are home (clicker training provides great mental exercise for dogs, which serves to tire them out, too, and relieve boredom).

So Lulu has taken up shredding her pee pad that is in her cage (it's in my pics)  with her.

Maybe I'm just beiing dim (it happens) but I wasn't sure from your post what you meant  by her being in a cage.... If she is in a crate - lose the pee pad.  The crate is not for peeing in, pee pad or no.  If the "cage" is an x-pen, just put down some paper if you want to protect the floor from accidents.  Less expensive and less likely to cause problems if she continues to shred.  Get busy with the housetraining, and lose the paper/pads ASAP. Look into gettiing a dog walker, or helpful neighbour to check on her if you are going to be out a long time.

Likely, she is just bored.  Address that by tiring her out before you leave for work and give her SAFE things to chew and play with.

Well the first time I tried the bitter apple was on her leash so she wouldn't chew as we were walking.  It didn't stop her, I actually think she liked it....weird I know BUT the bitter apple doesn't slow her down one bit.  She actaully licked the leash for a couple walks after it got sprayed.  Never heard of Wizdog so I will check it out.  On Friday I did keep her in the computer room with a peepad toys and her crate. She didn't shred the pad.  I only give her a stuffed kong when I leave just to distract her enough from yelping till Im out of the door.  One of the reasons I think that she's being stubburn is because after we go for our morning walk she will pee on the floor 5inches away from the peepad.  She will only do it when she sees me getting ready to go in the morning.  If I am home for the day she will be 100% different.

What is clicker training? 

She has a "cage" that she stays in during the night and when Im gone during the day.  Her cage is actually a rabbit cage that fits her bed toys and peepad and some room to strech out.  I don't put her in her "crate" for the day when I am at work.  I use the crate for car rides and she goes in it to sleep sometimes while being at home.  She is walked at least 3 times a day so I only have to peepads there for emergencies.  She does use the peepads 90% of the time when I am at home so I think her housetraining is a lot better lately.  My neighbour does come check on her when Im out for longer periods of time and she's also taken her to work a couple days to keep Lulu busy.  I can come home at lunch everyday BUT I think seeing me will upset her allover again and thats why I stopped doing that.

Thanks everyone for all the suggestions....one of them will work eventually
