Chihuahuas are becoming very popular - they have been featured in TV ads and movies like Legally Blonde in recent years.
Their small size,averaging two to six pounds, makes them easy to take along with you on errands and trips. They do need lots of exercise and are very sensitive to the cold. Because of this they are primarily indoor dogs.
They can be difficult to train as they are very dominating dogs for their size. On the plus side, they are also nondestructive to your home and belongings.
Chihuahuas are very affectionate and do need a lot of attention. They have less tolerance for children and may snap at toddlers who handle them roughly.
They make good watchdogs although like most small breeds they may bark too much at times.
Possible congenital defects include deformed spines, knees, dislocated shoulders, heart and breathing problems, hemophilia and brain swelling.
