My Chihuahua Sam, is the runt of the litter. He was born with some medical issues ( he was not breathing) and needed to be resuscitated at birth. He was only expected to live for five years. Sam is my first and only dog and with a lot of love and careful care, Sam is now 14 years old. I have learned with Sam that he is not the typical Chihuahua. He is extremely active, has a personality all his own, thinks he is human, is loyal, protective and acts as if he is a Rottweiler. Love your pets, because what you get back is far greater than what you gave.
