Chihuahua care tips
Training and exercise
Chihuahuas are very intelligent and highly alert dogs. They want to please and respond well to positive training practices. However, they can also seek to dominate their owners and be somewhat temperamental, so you’ll need to make it clear who’s in charge from the very beginning with consistent training and appropriate boundaries.
Chihuahuas love to play and run and can get enough exercise even in a small indoor space. Short walks are enough to keep them in good shape and overexerting should be avoided. The members of this breed excel in obedience training and other canine sports.
Chihuahuas have different grooming needs depending on their coat type. The smooth-coat variety requires only occasional brushing and regular baths, whereas long-haired Chihuahuas need brushing about once a week in order to prevent the coat from matting and tangling.
Their teeth need to be brushed regularly and their ears should be cleaned frequently in order to avoid ear infections.
Due to their small size, Chihuahuas usually need up to 1/2 cup of dry dog food a day. However, your dog’s exact food intake will be based on their age, size, and activity level. You should always consult with your veterinarian to make sure you are providing optimal nutrition to meet your Chihuahua’s dietary needs. Be sure to keep an eye on your dog’s daily food intake in order to prevent them from getting overweight.
Chihuahuas have weak teeth due to the small size of their jaws and require regular dental care. Make sure to provide a diet that requires chewing, as well as dental chews to help reduce plaque. Like many small breed dogs, Chihuahua’s may need more regular dental cleanings and extractions from your veterinarian to keep their mouths healthy and pain-free.
Life with a Chihuahua
Due to their small size, Chihuahuas are perfect for students and people living in smaller homes or apartments. They’re also ideal for those who don't like taking their pet out on cold days since these dogs can be easily taught to use a wee wee pad or litter box indoors. However, when you do take your Chi out, avoid leaving them alone or unattended for long periods of time as their small size makes them a potential target for attacks by larger dogs or wildlife.
If they’re properly socialized from a young age, Chihuahuas usually get along well with other dogs in the home, and even with cats. They are also good with older kids but not always an ideal pet for families with very young children, as they’re fragile dogs who may be unintentionally injured by young children. It’s always smart to supervise your children around Chihuahuas and teach them how to interact with these tiny dogs in a safe and respectful manner.

- Hypoglycemia - a condition of having low blood sugar, which affects a dog's energy levels;
- Hydrocephalus - a condition where cerebrospinal fluid accumulates in a dog's skull

Chihuahua breed history
The origins of Chihuahua dogs aren’t very clear. One theory is that Chihuahuas descended from Techichi, a Central or South American dog that dates back to the 9th century and the Toltec civilization. The Techichi dogs were discovered by Americans visiting Mexico in the 19th century. They were prevalent in the State of Chihuahua, thus gaining the name we know them by today.
The second theory says that short-haired Chihuahuas are a cross between small hairless dogs from China that were brought to Mexico by Spanish traders and small native dogs. The long-haired variety is believed to have been created through crosses with Pomeranians or Papillons.
The breed was first registered by the American Kennel Club (AKC) in 1904 and today, Chihuahuas are ranked 34th on AKC’s list of most popular dog breeds.
