11. Yorkshire Terrier
Yorkshire Terrier dogs are pretty independent and willful. These guys can also be stubborn. They’re especially difficult to convince to go outside and do their stuff when it’s wet or cold out.
Yorkshire Terriers will think you’re bossing them around with your strict training and would rather ignore you. Additionally, these teeny tiny pups also have teeny-tiny bladders, which means they can’t hold it for long. Thus, frequent potty breaks are a must.
