I've never had a Chihuahua. You are getting lots of good info here. There are also other threads about chihuahuas. All the chihuahuas on The Dog Whisperer are products of owners that don't train their small dogs. Small dogs have a real problem taking over their owners. People think that since they are small and cute they don't train them properly. Jumping up on people, not leash trained, not housebroken, and most common and one of the biggest mistakes is scooping the dog up whenever it's scared. This makes the dog more fearful and causes a lot of these behavior issues.

If you decide to get a chihuahua you have to do your research on the breed as much as any breed. Make sure you do plenty of reading on how to properly train your chihuahua and NEVER coddle the dog. They do look like puppies all their lives, but they are dogs. They need proper training to become a well behaved family member.

Good luck!
