Several years back I had access to a letterpress and (of course!) designed an alphabet based on dog breeds that start with that letter.

They are:
American Pit Bull Terrier, Boxer, Chinese Shar-Pei, Doberman Pinscher, English Bulldog, French Bulldog, German Shepherd, Harrier, Ibizan Hound, Jindo, Keeshond, Labrador Retriever, Maltese, Neapolitan Mastiff, Otterhound, Presa Canario, Queen Elizabeth Pocket Beagle, Rottweiler, Staffordshire Bull Terrier, Tosa Inu, Utonagan, Vizsla, West Highland White Terrier, Xoloitzcuintli, Yorkshire Terrier, and... there are no breeds that start with Z in the english language! so puppies playing because everyone loves puppies :)

I have 3 of the prints on this paper left, note me if you'd like one.
Hand printed custom design on the letterpress. 18"x5.5" (approx)
$18 + shipping

I have 4 copies of a couple other versions as well (same price) over on dA:
