Puppy raising? Good idea? Any tips or suggestions?

I'm an Adoptions Counselor at Maricopa County Animal Care & Control. We're the nation's second largest shelter and therefore, we take in a LOT of homeless dogs. To try and help out, I fostered a Chihuahua for a little over a month, and I absolutely loved it. I'm nearly ready to start fostering again.

However, this time; I was considering puppies.

Underage puppies are forced to be euthanized if we can't place them in rescue or foster homes, just because we're so overcrowded and we simply can't keep them until they're grown up. My heart goes out to the little guys.

My concern is that I've never raised puppies before. Is it REALLY as horrible as people make it out to be? I would only be keeping the puppy for a maximum of 4-6 weeks, though more than likely in the 2-5 week range. What are some things I need to know? I would not foster puppies who need to be bottle-fed, since I do not have enough time in the day to do that. But with things like socialization, training, chewing, pooping and peeing all over the house... I'm not sure how to handle it, since I've never done it before. Is it horribly difficult? Do puppies really tear up everything? =/

Would fostering puppies be a good idea?

If you guys need any extra information, just ask. I'll edit my question with the answers. :)

Thanks.
Update: Kryptonian - I tell them how much work it is. I know it's a lot of work; but considering I've never actually experienced raising a puppy, I can only tell adoptive parents what I've heard. I usually try my best to get the older dogs adopted out anyway.
