@Concretehunter: Cute dogs! Im personally a cat person, but their so adorable!
Also not sure what you meant by what to do with them, but if there not already, get them fixed.
My brother has a dog that lives where i do, he's old, and a testicular cyclops, but recently a female went into heat and it was awful. He was miserable because he didn't want to be a bad dog, but couldn't control himself, and we were miserable because he whined and howled all night. Since you got them from the pound im assuming they aren't pure bred or what not, so you probably wouldn't be breeding them or anything. Tying them to a sled and using them to help with groceries is always good exercise (:
