Maggie is three months old and 90% housebroken. I always take her out on a leash, even though our property if fenced. The reason is that when she is finished doing her business, I pick her up and bring her back into the house. The second reason is so that I can protect her. We too have very large dogs next door, 5 of them. They act like they can eat chain link fence. Bless her little heart, they would almost scare the pee out of her. I kept reassuring her that it's okay. I know it's okay because I'm on the other end of the leash. I guess I'm lucky, she never would use the wee wee pads. I tried them and she just preferred to go outside. Fine with me. That was my intent anyway. I just wish she would use a pad when it's raining. Rain, sleet, snow or shine--she doesn't care. Anyway, the big dogs don't scare her anymore. She just ignores them. I don't know if it's because she knows they can't get to her, or because I have told her many a time that it's okay. Good Luck with your baby.

Coco and pee pads
 

My little Coco is about 3 months and she's about 90% potty trained on the puppy pads. I think animals instinctivelly will go outside but it's the indoor puppy pad training that's hard. My little Coco likes to pee every 30 minutes, because she drinks a lot of water and has a lot of energy. So running around so much gets her tiny bladder working. So every 25 minutes or so I place her on the pad and she tries to run and I bring her back on it. She just looks at me and says, "fine have it your way" and pees right on it. Other times she just goes on it by herself when I'm not paying attention. But for the most part I'm always following her and keeping my eye on her. If I see her sniffing a lot,I bring her immediately to the puppy pad. If she goes on the carpet, I let the puppy pad soak it up so she can smell it on there next time. I also clean the carpets a lot so she doesn't go in the same places on there. Once the scent is gone, she won't remember that that's where she went last. I am very much a strict mama about potty trianing. While I don't get mad at her for accidents, because she is just a baby, I do say a nice stern NO! and clap my hands, when I see her squat. I quickly rush her to the pad. It's usually too late but it's the idea I want her to learn. I hope this helped. It's ok Stewiesmom, my mom is the same way. Loves her but also loves her carpets to be clean.

I would try putting the pad in some sort of bin like FastEddie said, if you continue taking the pads to her house. It might be that Stewies really excited when he goes to Grandma's and doesn't have time to make sure he's actually on the pad. If you put it in some type of box/bin he will have to get inside and he will definately be on the pad. We got a container at Wal-mart that is like 4 inches high and its meant for storage. We got it on the aisle with all the rubbermaid storage boxes and stuff. Her pads are actually just a little big and go up on the sides a little but if she's in the box going, she's going on the pad. Sometimes she would walk off in the middle of going or not be completely on the pad but this fixed that.

Here's what I have done:
every time she has slept, eaten or played I take her outside for a walk of 20 minutes. I bring treats and everytime she pees or poops I give her one followed by "Gooooood dog, you're such a gooooood dog" and big smile :)
I walk her as the first thing in the morning and as the last thing before I go to sleep. I walk her as soon as I get home - and after 3 months she was hoursebroke :)
Now I just let her out into the garden at the times where I would have walked her - she does the rest :)

I do take her for a walk now and again - she loves to snif around the neighbourhood and it is much more challinging for her to snif than to stay around the house all day :)

My Cheri used to do that - I take her outside before going in the house.
