 
"What are you looking at?"
"Chis aren't dogs, I'm convinced -- they are 
      four-legged babies." -- from Chihuahuas@OneList.com
Being experienced Chihuahua owners, we must say each dog has their 
      own unique personality; this is a very individualistic breed. However, a few 
      generalizations can be made. Chihuahuas are graceful, energetic, and 
      swift-moving canines. They have often been described as having 
      "terrier-like" qualities; that is, the qualities of being alert, observant, 
      and keen on interacting with their masters. They are extremely loyal and get 
      attached to one or two persons.
These tiny dogs are certainly unaware of their diminutive stature: 
      they can be bold with other dogs much larger than themselves, and protective 
      of their masters.
 
Look out Great Danes!
They are fiercely loyal to their 
      masters and wary of any strangers or new guests introduced into the 
      household, which the Chihuahua considers to be its personal domain. For 
      these reasons, Chihuahuas make good watch dogs (not guard dogs, though!). 
The Chihuahua needs a great deal of human contact: touching, 
      petting, and general attention. If the Chihuahua does not get this, she or 
      he will use various attention-getting tricks until you give her/him 
      attention. We have five and never an hour goes by that we don't have someone 
      cuddling up!
Keeping more than one Chihuahua can greatly ease the dog's stress 
      when left alone each day if the owner works. (They will compete for your 
      attention when you get home, though!)
