Top 10 Smallest dog breeds in the world. The “itty bitty” dogs are just too cute! I am amazed at how small they are! I would be afraid I would hurt one by accident if I had one. I tend to be accident prone and would feel awful if something like that happened. I love to snuggle and cuddle with them! This video was too cute! I hope you enjoy it as much as I did! Let us know if you have one of these dogs in the video. We would love to hear from you.
