Aye, Aye, Aye! My dog is so bad!!!

If I had a dime for every time I said, "Aspen! No!" I'd be one rich chick. I'm serious you guys! She's really bad! I love her dearly, but, she makes me want to pull my hair out sometimes! She's the greatest companion and a dear friend, but she's also very, very mischievous. Take her potty training for example. She knows it's a no-no to go indoors, but she will sit outside on her cable and hold it until she comes inside. As soon as she comes in the house, she tinkles. I wake up every morning to a wonderful pile of unmentionables in front of the living room door in the mornings. She refuses to use the puppy pad. We're going to get a kennel for her to stay in a night but that's a couple of weeks down the road. Ugh, why won't she get it? Don't get me started on the way she steals the kid's food. I have to put her outside when the kids eat or she will find a way to get their food. Trust me, she'll find a way. I am always getting on to her for eating the cat food and going in the laundry room. The litter boxes are in the laundry room and I certainly don't want her in there chowing down on the cat's waste. But, for some reason, she finds this a tasty meal. Gross. When she plays with the kids she gets way too rough. She's trying to be playful, but she winds up hurting them instead of playing. I hate to get onto her for that, but I can't have her hurting my babies. It's one thing after another with her. This is one journey I won't soon forget. I'm thinking of obedience school for her, but I'm not sure about it. Anyone got any tips?
