Deacon, my dog was named at the shelter since he was found near a church off the interstate.
Buddy, daughter's dog, was named at the shelter since he was super friendly.
Sammy, our tuxedo cat, was named by shelter and not sure how he got that name.
We have had dogs: Queenie, Ajax, Agamemnon(all bulldogs), Fritzie (poodle/scottie), JD (pit bull, numerous things for the J.D.), Muttsie (some hideous Heinz 57 dog my father got somewhere), Malcolm Felix Webster III (Black Labradork) Names came from various sources.
Cats: too numerous to count and think of, buy by and large, Charlie, Clyde, Sammy and Tinkerbell were the best.
