The Chihuahua typically weighs 2-3 kg, stands 15-23 cm, and lives 14-17 years.

Consider this breed if…

you want a small, long-lived companion for a flat or one-person home,
you'll commit to real training so the big attitude doesn't run the house,
your idea of exercise is short walks and indoor play, not running,
you can protect a fragile 2-3 kg dog from falls and rough handling.

Do not consider this breed if…

you have young children who play rough - this dog is easily injured,
you want a robust dog for hiking or outdoor adventures,
you'd let the cuteness excuse snapping and no training,
cold weather is common and you won't manage its sensitivity to it.

Frequently asked questions

How much does a Chihuahua cost?
Expect roughly $500-$1,500 from a reputable US breeder, with tiny or fashionable types priced higher. The purchase is only the start: even a small dog needs regular dental care, and toy-breed issues like luxating kneecaps or a collapsing trachea can bring surgery bills. With a 14-17 year lifespan, lifetime costs still add up - budget for insurance or a fund.
Are Chihuahuas good with kids?
Only in the right home. They are fragile at 2-3 kg and can be easily hurt by rough or unpredictable handling, which often makes them snappy in self-defense. They do best with adults or older, gentle children who understand how to handle a very small dog.
How long can a Chihuahua be left alone?
An adult can usually manage around half a workday once used to it, but this breed bonds intensely to one or two people and dislikes long isolation. Regular full days alone tend to bring barking and anxiety. A home with someone around much of the day suits it best.
Are Chihuahuas aggressive?
They are not aggressive by nature, but they are bold and will stand up to much bigger dogs. What looks like aggression is usually fear or a lack of training - many are carried and coddled instead of taught rules. With real training and socialization, a Chihuahua is confident and well-mannered.
