Need A Free Yorkie From Shelter In Spring,tx. Can You Help?

Father's day is coming and our anniversary, husband said search for a small dog. I have always wanted a Yorkie puppy. I have no dogs and a cat(younge). I would like to know of local shelters maybe. I cant afford an expensive one right now. We would love to adopt. We have 5 children and this would be a good experience for them. Thanks Jojo
