Coloring book with art and text by L. Royer, entitled Life of a Chihuahua Coloring Book (2009). Royer has done several other books like this
for numerous dog breeds.
This chihuahua wall calendar is more than a calendar in that each month can be turned into a greeting card, so it's a spiral-bound book of one-dozen tear-off cards including six color envelopes. The photo set stars the dancing duo of Gadat and Ping Ping, chihuahuas who do the cha cha cha.
