This is what we saw for the past few weeks. Our littlest dog (under 20 lbs.) taking up all of the big dog bed. The other, bigger dogs would stand there staring. Then they would pace around and come back to stare again at Nikki. She did not budge. Our greyhound Cassius could spend fair amounts of time staring at her, to no avail. Finally, the last two days, I have seen this.
Nikki still has not budged but Cassius has figured out that there is room for both of them. They may even like it. It’s warmer this way.
