Am I the Asshole for asking for an apology from my mother?

Yesterday I (36f) stayed home from work as I did not feel well and spent the entire day asleep. I woke up briefly at 10:30 to let my dog (a german shepherd) outside but otherwise I was dead to the world until about 5 o'clock. My phone is set so that from 8-6 on work days it is automatically silenced. I live in a tiny house on my parent's property due to having AuDHD and the messed up housing market. When I woke up I discovered that I had several missed calls from my mother and that my tiny house had no power. What I then learned was that she had cut off the power because she was upset with me for leaving my dog outside all day and not answering her calls telling me to bring him in. Now it was cold yesterday (37F with less than an inch of rain in the afternoon) and I definitely had not intended to leave him outside all day. But he has access to my insulated crawlspace and a covered porch with a tent bed that he can curl up in. Now this morning I asked my mother to apologize for cutting off my power and said that was toxic behavior and completely uncalled for. She laughed at me and said I should ask you all for judgment.
