They have all breeds, and even a room dedicated to the smaller and younger pups. The best way to preview is by using the website and filtering based on your preferences. For true availability, though, it is best to go to the shelter and meet your new pet in person.
I've seen them have Chihuahuas and 6-9 month old dogs. Younger than that are usual adopted quickly. You can try visiting them. You might be in luck. Alternatively look at adoptapet.com
