M.S.
I'm a little late responding to this but there is a rescue group that is based in Carrollton called Lexee's Legacy. They are a "for life" organization. My mom and stepdad adopted a dog from there about 6 yrs ago and had a wonderful experience. All of the animals they looked at were clean, healthy, and very well taken care of. They rescue dogs and cats. Here's their site:

Good luck!
