If you already decided that a Chihuahua is the perfect breed for you, you did your research on this dog and you analyzed every perspective that you needed in order to take such an important decision, I have to stress upon a few little things, such as what is a Chihuahua capable of doing and what is not.
As you can imagine, every dog has the tendency to believe he's the meanest and toughest one around the neighborhood.
That is the case of the Chihuahua as well; you will probably smile while reading this, but this little dog has a powerful bark and, even though he does not look like the regular watchdogs, he really has a strong feeling of alert, alarm and propriety.
Well, of course you realize that due to the fact he is smaller than any other dog -Chihuahua is also called a "Toy Dog", if you did not know that already, the possibility that he gets injured is quite higher than the average rate.
This can happen from the innocent play between him and his master.
Therefor, you need to be very careful when you tend to overwhelm your dog with funny activities.
The health of your Chihuahua is a matter that needs extra attention, so if usually for a dog is normal to take him to the veterinary for his annual checkup, for Chihuahua this process has to be doubled.
Do not forget any of the recommended puppy shots and the medication against any internal or external parasites.
Your "Toy Dog" is basically a toy only at first sight, be careful not to break it!
