Mei Mei the dog was not at all happy to see a family of bears chilling out in her owner’s backyard.

The bears are regular guests at Deedee Muller’s home in Pasadena, California. The mother bear sought out the water fountain to lazily cool off, while her cubs gambolled playfully close by. Mei Mei was having none of it and kept barking until the bears left. Credit: Deedee Mueller via Storyful
