Thumbelina is smaller than her siblings but she's twice as tough. She loves to play and run, and can stand up for herself when she needs to with her siblings. She's great with big & small dogs, children, & cats. Her mom is a collie, but we're not sure what her dad is...I'm guessing she'll be 30-50 lbs full grown. She is so smart she already knows how to use the doggie door. If you are interested in meeting or adopting Thumbelina please email us at fochp@yahoo.com
