You can fill out an adoption application online on our official website. Hi, I'm Serena! Serena is an 9-week-old Pitbull/maybe Chihuahua mix that came in with her siblings! She is fairly small, so we don't think she's going to get very big. Like any young pup, Serena is learning everything for the first time and will need guidance as he grows. If you're ready for puppy energy, puppy kisses, and lots of adorable moments, please fill out an application!
