Description: Weighing in at 2 to 6 lbs, Chihuahua’s are the smallest breed of dog, but can be agressive if they are not socialized properly from puppyhood. Because they are so small, Chihuahua’s will snap at teasing children, so they are not a good choice for a family. Although they are suspicious of other people, they have a great loyalty for their owners, and would like to go everywhere with them if possible.
They are ideal apartment dogs and watch dogs, as long as you take them out to play and exercise. Make sure to play with them and provide them with plenty of toys to keep them entertained.
Chihuahua’s come in short-haired and long-haired varieties. They stand 6 to 9 inches tall. They can be difficult to train, but are intelligent, and with patience they will learn.

The negative personality traits of Chihuahua’s can be successfully overcome with extensive socializing while they are young. If you want your Chihuahua to be friendly and tolerant of strangers and other dogs, make sure you have plenty of time to give attention to your puppy, and read up on how to socialize puppies.

Health Problems: Chihuahua puppies are open born with a soft spot on their skull. This should be hardened by adulthood, but they must be handled carefully while young.

Life Expectancy: 15 years

Living conditions: Chihuahua’s are good apartment dogs. They get cold easily, so they should be kept in a warm environment, or provided with a doggy sweater. They enjoy walks, which will keep them in shape, but they really only need the exercise they get from playing inside.

Grooming: The Chihuahua requires occasional brushing and a bath once a month.
