7. Yorkshire Terrier
This little dog may be known for their little package, but they are also bib explorers. They are nicknamed “Yorkies” and are the truest of Terriers even though they are actually a toy breed. They don’t weigh more than 7 pounds usually, but anyone who is around them long soon realizes that while the package may be small, there is a lot of dog lurking inside. They love to be indoors and out. They are a perfect companion dog.
