I just adopted a 5 month old Welsh Corgi/Cairn Terrier mix. She is the cutest thing! Joy is Hell on Wheels! We found out what a jumper she is. She jumped over 2 large trash cans which totally amazed us. She has so much energy! She never quits. I thought puppies took naps during the day. Not this one. I welcome ALL suggestions & help. Thank u, Katrina & Joy aka Houdini.
