Good for you wanting to adopt. You may have to keep checking the websites of various shelters. Two of our dogs came from South Lake Animal League (aka The Animal League). You have to be patient because they may not have the dog you are looking for at the moment, but you never know who they will be getting in next.
The Animal League - Central Florida Humane Society And for anyone reading this, if you are a senior citizen and adopt a senior dog (my dog was 7 years old), you get a discount on the adoption fee. Good luck in your search.
