Things to be concerned about;
Katie is a female I'm assuming. Introducing another female dog could be a little tricky, especially if both haven't been spayed. Females tend to exhibit more resource guarding tendencies than males. It could cause problems.
Katie is only a year old, and still a puppy mentally and physically. A new dog may confuse her and she may revert back to puppy behavior to keep the attention on her, she may also begin a pattern of negative behavior to recieve attention of she feels the new dog is getting too much attention.
There is a lot of difference between a year old dog and a three year old. Unless Katie is very forward and dominant, a three year old could easily intimidate her too much, which would be bad for everyone involved. I would really try to keep that age a little closer together. If Katie were the three year old I wouldn't be as concerned.
I would ask for the rescue/adoption to be on a trial basis for a few weeks to give you a chance to see how they interact with each other, and make sure both dogs are up to date on all shots. Look for food aggression behaviors and over dominance issues.
I have two females. One is just over two years old and the other is just over a year old. I got the two year old this past May, and the year old this past August. Mine knock the snot out of each other playing and mock fighting, steal cookies from each other, and then sleep on top of each other at days end. It can be done.
