Temperament
Chihuahuas are a high spirited and intelligent breed that loves to stay with its family. This dog thrives on human companionship. The Chihuahuas though a family dog will not do too well with families who have younger children as they might want to pick them up but are bound to drop them on the floor. This could lead to injuries in your fragile dog.

The Chihuahua contrary to its size is bold and confident, in fact it has terrier like features and an alert nature so they will be the excellent watchdog for the family but do not vouch for him or her to guard you. One of the most important thing you need to remember at all times is that it is integral to start training right from the beginning when he or she is a puppy.

Chihuahuas are not an easy breed when it comes to breeding. They can be a lot of complications involved in their mating.
