My smart dog sneezing on command, and her accomplice

Berkeley is a 4 year old Border Collie/Labrador Retriever cross. She is wicked smart. Penny is a 2 year old Miniature Longhair Dachshund. She is noticeably not as smart, but adorable anyway. People who visit our house are always shocked and amused by Berkeley’s sneezing trick, so I thought I’d put it on the interwebs for the masses to enjoy.
