Daisy is trained to ring a bell on the floor whenever she wants to go out into the backyard.
When a mama bear and two cubs showed up to swim and play, Daisy got excited, ringing the bell repeatedly as she watched the trio through the door glass.

"So we bell-trained our dog," Tiffany Kress says in the video posted to Instagram. "But I don't think she can go out right now."
Instead, the family and Daisy all watched from safely behind the glass door as the mama and cubs played in the water for a while, then left the yard without further incident.
The video was recorded in July. Kress says bear sightings in the area have become more common - almost daily - since the Bobcat Fire in September 2020. But this is the first time she's seen them climb over the wall and swim in her pool.
