My dog Daisy, the one who looks like she could be Buddy's mother, stands up on her back feet all the time and even walks across tile floors in that stance. It's her Miss Cuteness pose, and she does it when she's trying to get my attention, persuade me to feed her something, compete for attention with my other dog, or when she's extremely excited about something. She looks like a little pudgy beige circus dog when she does it. It must feel good because she's almost 10 and still assumes that pose at least once a day. She can hold it for up to about 5 minutes at the top limit.
