As a Chihuahua owner and volunteer for the National Chihuahua Rescue and Transport Society, I strongly recommend this book. I use it all the time. It is specific to the breed and covers all phases of a Chihuahua's life from weaning to the need for euthanasia. It covers anatomy, breeding, training, and genetic predispositions of Chihuahua's. Upon reading it to completion you will know everything there is to know about these tiny canines. One of the most useful chapters deals with the 5 minute physical that demonstrates the basic exam that you see your vet do, when he examines your dog. It has great pictures, but if you can only buy one book on "Chi's" this is the one I recommend.
