Most dogs that are available as a rescue have very special needs be it physical or behavioral. These are not like a dog that you get from a breeder. They can very difficult to house train and may not ever be completely housebroken. They can also be very standoffish and even aggressive and it is possible that they will never be a cuddly little lap dog. The rescue organizations just want to make sure that the dog goes to a forever home that understands what they are getting into and is prepared to give the dog a loving and lasting home no matter what happens.
You would be surprised at how many of these dogs are adopted out only to be returned or who have gotten lost. This is why most organizations are so strict, they would rather error on the side of turning down a good home than to place the dog in a home that is not prepared for it. These little guys have been through so much that they deserve the very best forever home possible.
