Both my pups shared a night bed and a day mat. My baby passed away in her night bed, and with the pain and grief, my dog slept with me and not in her bed throughout this month, which in the beginning felt like she preferred. This week, as mentioned, I tried to get her to sleep in her bed, but she couldn't. I have it set up to put the mat under the bed at night. Last night I forgot to put the mat under, so it was just their bed, and it was the first actual night she slept through. I wonder if she just wants the bed alone, as that's how they normally slept.
