1. Chihuahua Although they are barely six to nine inches tall and weigh three to six pounds,
these tiny canines are among the longest-lived dog breeds, typically surviving up to 16 years.
2. Manchester terrier In the 19th century, this tiny pup was bred for rat
extermination and rabbit coursing.
While the Manchester terrier may still pursue small creatures, it's mostly curious.
The breed is known for being loving with family yet shy with strangers.
