They need a bit of daily exercise; but good Chihuahua information is, they can get all the vigorous physical activity they need from running room to room in a house or a small apartment.
In terms of living arrangements, they are an indoor dog and should not be kept outside. There is nothing wrong with having him explore the yard awhile each day, but this should only be temporary.
They absolutely hate cold temperatures, we keep sweaters on ours and they still will run to seek out warmth and coziness,
it's a good idea to keep them in pairs so they can play together, they will keep each other warm by sleeping on top of each other.
Chihuahua Information About This Teacup Stuff?
Have you heard these phrases?
Some breeders use these cutesy phrases as "marketing terms" for the different weights that Chihuahuas come in, go here for Chihuahua facts
These phrases are all made-up, from all recognized Chihuahua information; the only classifications that Chihuahuas should be put into is Smooth Coat and Long Coat, i.e. you have a Smooth Coat Chihuahua or you have a Long Coat Chihuahua.
Chihuahuas do come in different weights, but they do NOT come in different weight "varieties". Whether they weigh 2 pounds or 6 pounds or 10 pounds, they are still Chihuahuas.
Pet-quality Chihuahuas (that is, those bred or purchased as companions rather than show dogs) can, and do, range above these weights, to 10 pounds (4.5 kg), or even more if they have large bone structures or are allowed to become overweight.
This does not mean, however, that they are not purebred Chihuahuas, it only means that they do not meet the requirements to enter a conformation show.
For the show ring, they must weigh less than 6 pounds, but many individuals weigh up to 8 or 10 or even 12 pounds. These larger dogs are certainly sturdier, so don't dismiss them as good pets.
Grooming is a minor concern. They come in two coat types; short-haired and long-haired. It may take up to two or more years before a full long-haired coat develops.
Short-hairs need very little brushing, perhaps once a week. Long-hairs will need a brushing twice weekly. I have both long and short hair, I brush them often because they love it and its very relaxing to me as well.
Fortunately, there are no major health issues owners need to worry about.
However, minor concerns do exist but they are very rare, including: Hypoglycemia,
pulmonic stenosis, patellar luxation, and hydrocephalus.
And one last common trait that many Chihuahuas display is called molera, which is a soft spot in the top of the skull that results from an incomplete fontanel closure.
I do NOT recommend a Chihuahua under 4 pounds. These individuals are great risks in the health department. Their bones are extremely fragile. There is not enough room in their mouth for healthy teeth. Their internal organs are often weak and can fail suddenly. They tend to have great difficulty regulating their blood sugar and can suddenly fall into hypoglycemic comas.
They have a longer lifespan than many dog breeds, living up to 20 years in some cases, with approximately 16 to 17 years being the norm for a healthy dog.
