Well the chi one is really starting to come together. the 14-18 lifespan is still a bit much tho lol Id say more around 8-12 and that depends on being from GOOD BREEDING (health tested parents etc..)
as for this line..
Some bark, some are temperamental, and others may be timid.
I would change it to:
Without proper training and socialization, some have the tendency to bark a lot, be tempermental and very timid. some of this is also the result of bad breeding
and maybe add something like: "For a friendly, healthy, happy chihuahua, its very important for find a GOOD breeder who health tests their dogs and breeds friendly good representatives of the chihuahua breed.
The Chihuahua club of America website
Chihuahua Club of America
is a great place to find quality breeders for you future chi!
The proper temperament of a chihuahua is:
Alert, projecting the "terrier-like" attitudes of self importance, confidence, self-reliance. very devoted to their owners and are sometimes known as "velcro dogs".
Maybe also add a statement about TEACUPS.
there is NO SUCH THING as a teacup chihuahua. Breeders that use this term are ONLY breeding for size and not for health, and these tiny tiny dogs are often times very unhealthy.
