Some people's kids...

Probably the carpet was peed on by the dogs and the people decided after that to put the dogs in the garage but the damage had already been done. More than likely they slept w/the little girl and they probably peed on the bed as well, which is why it soaked all the way through. Believe me, after cleaning houses for a living, I'm not surprised by anything that I read or hear. I could tell you horror stories (but I won't). This is mild compared to some of the things I've seen. As for removing stains and odor, Cataholic and Wombat gave you some good advice so I have nothing further to add except to say that I'm sorry that you have to go through all this just to make your home livable. Can you imagine what these kids are going to be like as adults? A scary thought.

I'm not a kid person at all. I love my neices and nephews and they are very well behaved. However, the problem isn't the kids, it's the parents 100%. The problem isn't the dogs, it's the owners 100%. You have to have a license to drive a car. There should be some sort of parenting skills necessary to have a kid. Any fool can have a kid. It takes alot of work to be a parent.
Good luck on your destinking. The price you pay (or don't) for a foreclosure.

Just spoke with two women I work with in rescue. Both SWEAR by Anti Icky-Poo!! I read the container and it swears it gets rid of urine in concrete!!!! You can get it online. I know you may need a gallon, but it might be worth a shot!
