Has anybody ever filled out an online adoption form? Does the shelter usually make it a first come first serve type of thing? I really want to adopt this puppy, and I would like to know..what are the chances of getting him? Thankyou.
Could somebody also tell me some basics on Chihuahua's? Their personalities, etc..
Of course I am going to read up on them, but some pointers would be great.
