Before you seek Chihuahua puppies for sale, keep in mind that you should never underestimate this diminutive breed of dog. While they may be tiny, in their minds they are as big as any Mastiff on the block. They have big hearts, and give -- but likewise demand -- lots of affection and require as much time and care as dogs three, four or five times their size -- and are worth it.

One of the keys to being a happy Chihuahua parent is to ensure its socialization gets as much attention as his or her care and feeding. These dogs believe this is their world, and everyone else, especially other dogs and even children, are just living in it. Because of their assertive nature, some Chihuahuas may get the reputation as being snappish. But their small but sharp teeth are their only means of self-defense, and sometimes the only way to make their presence known.

From the time you see that Chihuahua puppies for sale sign, you need to be thinking of how best to socialize the newest member of your family. The easiest part is handling the little cutie. They enjoy being held and touched and most likely will reward you with kisses; they are people-centered pets. Be sure every member of the family and even friends get involved in your Chihuahua's socialization. The more people they know, the more people they like. Also, cautiously introduce them to other dogs and cats as well.

However, keep in mind that not every Chihuahua wants to be best friends with every child, dog, cat or houseguest, so be mindful of their protective nature.

The other thing of which to be aware is that these little dogs have equally small "central heating systems" and need to be kept warm. This is a great opportunity for the Chihuahua owner to play "dress up" with their dog. It is advisable those cold days, even long-coated Chihuahuas wear a jacket or sweater outside or even inside, if the house is cool. They may also need booties if they are outside in inclement weather. Seeing Chihuahua puppies for sale is an invitation to shop for your dog!

Their doggy wardrobe will be essential when they exercise. As small as they are, Chihuahuas, like other dogs, need to get outside to walk and play. While it may be tempting to tuck them under your arm or pop them in a cute pet carrier, it is better to let them walk in order to stay fit.

Who knows, properly dressed (both of you!), you and your Chihuahua could be mistaken for socialite and media darling Paris Hilton and her tea cup companion Tinkerbelle.

When looking to share your life with one of these cute little characters, look for a reputable breeder with Chihuahua puppies for sale and spend some time getting to know them and their dogs. Also be sure to ask about any special health concerns in the Chihuahua breed. Oddly, Chihuahuas, tiny as they may be, won't stay that way if you do not monitor their diets. They tend to gain weight easily, and you don't want them growing out of that designer wardrobe too quickly.

But, don't let these minor issues scare you off when you hear of Chihuahua puppies for sale.
