Best For

Chihuahuas are best for households with no small children or other dominant pets, and retirees or work-from-home parents who can provide lots of attention.

Chihuahua Traits

Chihuahua Temperament

Chihuahuas are charming little scamps with an eye for mischief and a sense of bravery that outsizes their physicality. They’re playful pups who enjoy a good romp or game, even though it may not last long (depending on their energy level). And they love to snooze on laps and cuddle—that is, after all, what they’re bred to do.

They like a lot of attention and are quite portable. But even though they’re easily carried, they do still need to learn how to walk on their own and be able to engage in normal dog behaviors, like sniffing, exploring and playing. In other words, don’t pop them in a purse or a stroller and tote them everywhere—unless, of course, it’s somewhere risky with lots of feet that could hurt a tiny paw, like an airport or street festival.

The Chihuahua dog breed is said to resemble a terrier with their demeanor and can become quite feisty, especially if they feel threatened. Some sites report that the Chihuahua bite force is 3,900 pounds per square inch (psi), but those so-called Chihuahua facts are wildly inaccurate, when a lion is only at 600 psi. (In truth, they usually inflict no more than a Level 1-3 bite, with no puncture deeper than half the length of one of their canine teeth.)

To help your Chihuahua puppy overcome a nipping or protective tendency, socialize them by safely and slowly introducing them to new people and places from the get-go and start training when they are young. Early training will also help this smallest of dog breeds become wonderfully friendly and receptive to all members of the family, including other pets.

How to Care for a Chihuahua

A Chihuahua puppy or adult, with their petite proportions and ease of portability, is easy to think of as low maintenance. In reality, Chihuahuas require daily exercise, regular grooming with special attention to dental and eye care, and early socialization and training. They are dogs—not toys—after all. The good news is they are so little, that grooming doesn’t take very long to get through. And they’re smart dogs who take well to proper training and socialization.

Chihuahua Health

Even though they have a life expectancy of 14 to 16 years, Chihuahuas are not without their health problems. Like many dogs who have been bred for millennia, Chihuahuas come with their own unique set of health issues.

  • Patellar Luxation: Also known as luxating patella, this condition occurs when the kneecaps slip or dislocate. It may require surgery (in extreme cases) or knee braces.
  • Hypoglycemia (low blood sugar): Because tiny dogs have very little fat storage, their blood sugar bottoms out easily. Symptoms include chills, shakiness, uncoordinated limbs, muscle spasms, difficulty standing or walking and, in serious cases, seizure and collapse. To help your Chi avoid developing hypoglycemia, make sure they’re eating a complete and balanced diet every day.
  • Bladder Stones: The Chihuahua is more likely than other breeds to develop one of two types of stones: bladder stones (aka uroliths or cystic calculi). Symptoms include smelly or bloody urine, inability to urinate, frequent urination and accidents in the house. Surgery may be required to remove the stones. To prevent them or minimize your Chi’s chance of developing them, talk with your veterinarian about possible changes to your pup’s diet.
  • Portosystemic Shunt (PSS): In this disorder, the blood supply that’s supposed to go to the liver is diverted. Then toxins build up. If your Chihuahua is not growing properly or has seizures, make sure your vet checks for this condition, which is treated with diet and medication.
  • Heart Disease and Other Cardiac Issues: Heart disease is a leading cause of death for this smallest breed. Chihuahuas are susceptible to several conditions, including valve disease and Patent Ductus Arteriosis. Symptoms include coughing, fatigue, weakness, a heart murmur and weight loss.
  • Hydrocephalus (excess fluid around the brain causing pressure on the brain): Because of the shape of their heads, Chihuahuas are susceptible to improperly fused skull bones. Symptoms include seizures, circling and an improper gait. When caught early, medications can be used to treat the condition. In some instances, surgery is needed.
  • Epilepsy: Chihuahuas can have seizures for several reasons, but if there’s no underlying disorder, then epilepsy is diagnosed. These are then treated with an antiseizure medication.
  • Scleritis: This is a hereditary eye problem the occurs when the white of the eyeball is inflamed. Because the sclera covers the entire eyeball, this condition must be treated promptly or the membrane will dry out and the eye will have to be removed.
  • Keratoconjunctivitis Sicca (KCS): Also known as dry eye, this common-but-painful condition occurs when the tear ducts no longer produce fluid. If your dog is pawing at their eyes, has discharge or their eyes appear dull as opposed to shiny, see a vet.
  • Glaucoma: Like humans, these tiny dogs can develop painful eye conditions that lead to blindness. Symptoms include a “bluing” of the cornea and redness in the whites, along with squinting and watery eyes.
  • Periodontal Disease: Extremely common in Chihuahuas by the age of 2, periodontal disease begins with tartar build-up and leads to gum infections and tooth loss. If not treated, the bacteria can get in the blood stream and affect the heart, liver and kidneys. Daily teeth brushing and regular dental checkups by your vet are key to preventing this disease.

Chihuahua History

Chihuahua history is ancient. The Chihuahua dog breed is named after the Mexican state of Chihuahua, where they originated and may have developed from the Techichi, the tiny dog kept by the Toltecs as early as the 9th century AD. However, one clear distinction between the Techichi and the Chihuahua: The Techichi was essentially mute, and the Chihuahua is, well, clearly not.

Another interesting Chihuahua fact: While the American Kennel Club did not officially recognize Chihuahuas as a breed until 1904, they were first noticed in the mid-19th century. And while they were isolated from other breeds for 9,000 years or more until Mexico was colonized, modern Chihuahuas retain four percent of their Chihuahua original genes that predate contact with European dogs.

So, where is the best place to find Chihuahua puppies today? You can find a list of reputable Chihuahua breeders on the American Kennel Club’s website. What’s the average Chihuahua price? Depending on the breeder, expect to spend anywhere from $500 to $1,500 for a pup, with the average dog going for $800. But for that, you usually get a dog who’s been screened for health and temperament issues, and they might even come with pedigree papers. You can also reach out to Chihuahua rescue organizations to adopt a Chihuahua or keep an eye out for the breed at your local animal shelter.


Are Chihuahuas hypoallergenic?

No, Chihuahua dogs are not hypoallergenic. Some people think that the short-haired (smooth coat) Chihuahua is easier than the longhaired ( long coat) for those who have allergic symptoms to dogs, but that’s not true. The Chihuahua sheds a low to moderate amount, and dander (and even their saliva) are what triggers an allergic reaction. The AKC does not list the Chihuahua as one of its recommended hypoallergenic breeds.

Can Chihuahuas swim?

Yes, like almost all dog breeds, Chihuahuas swim instinctively. Are they the best swimmers? No. While they don’t sink like Bulldogs, they weren’t bred for the water. So, some like it and some don’t. However your Chihuahua takes to water, remember their little limbs will tire easily.

How much should Chihuahua weigh?

The AKC breed standard for a Chihuahua’s weight is four to six pounds. Any larger than that is a flaw. Many Chihuahua pet parents overfeed their toy breeds. It’s important to remember that the smaller the dog, the less they need to eat. Quality more than quantity is the key.

What are the most common Chihuahua mixes?

  • Chihuahua-Cavalier King Charles Spaniel mix (Chilier)
  • Chihuahua-Dachshund mix (Chiweenie)
  • Chihuahua-Poodle mix (Chipoo)
  • Chihuahua-American Eskimo mix (Chimo)
  • Chihuahua-Miniature Schnauzer mix (Chizer)
  • Chihuahua-Papillon mix (Chion)
  • Chihuahua-Beagle mix (Chibeagle or Cheagle)
  • Chihuahua-Jack Russell Terrier mix (Jack Chi)
  • Chihuahua-Miniature Pinscher mix (Chipin)
  • Chihuahua-Japanese Chin mix (Chin-Wa)

Top Takeaways

The Chihuahua is a tiny dog who thinks they’re a giant. For singles, retirees and experienced pet parents, the Chihuahua is the ideal snuggler. But for those with young children, multiple pets, or a job that demands a lot of time away from home, the loyal, attention-seeking Chihuahua could prove challenging. This quirky, feisty breed is happiest when they’re unquestionably the king or queen of the home.
