is teacup chihuahua a breed?
You may see the Teacup Chihuahua referred as a new breed of companion dog but it is actually not a new breed at all. The term 'Teacup Chihuahua' actually describes a Chihuahua that is smaller than the regular dogs of the breed. There is no standard for how small a Chihuahua has to be for it to be classed as 'Teacup'.
