The Chihuahua is the smallest dog breed. I owned a Chihuahua that was a mix. It was slightly larger that the typical toy Chihuahua.  These dogs make great apartment pets. They are loyal and hearty. The can be very high strung. From the outside of my apartment, my Chihuahua sounded like a much larger dog by his bark. This was a good thing since his bark provided protection. Chihuahua’s are also very loyal and loving pets.  They are easy to keep. Sometimes it can be difficult to find a dog leash that fits properly if they are super small. Chihuahua’s live to about 15 years on average but since they are so small, they don’t have problems with arthritis that some of the larger breeds have.

You may be curious as to what is the smallest dog ever recorded. The answer is a Yorkshire Terrier that was approximately 3″ long and 1 1/5 inches tall at the shoulder. Now that’s a small dog!!
