A few on my favorite lists may change sometimes but for the most part it mainly stays the same. Mostly my list changes because I accidently forgot a breed or the like. lol

There is no way I can pick my alltime favorite, I have about 10ish breeds all tied for first choice.

Great Dane
Australian Shepherd
Border Collie
Rottweiler
English Pointer
Boston Terrier
Siberian Husky
Gordon Setter
Mixed breeds
Standard Poodle
