The other day when it sleeted all night, I went out at about 10 that night, and checked on my dog, big yellow lab, named Max. He was ok and bouncing around. I noticed the sleet had piled up by the back door, and shoveled it off. Went to bed and got up around 6 that morning. Max's pen is in front of my truck, and I went out to warm my truck up, and noticed the sun cover (trampolin type cover) I had over Max's pen had fell through, and the bad part was it covered his entrance to his house. He spent the whole dang night in the sleet. He was not wet, and he seemed to be in good spirits, but that still haunts me. I was so pissed at myself for not thinking about that could possibly happen. I never saw sleet building up on it, but its about 6 1/2 ft tall including concrete. I gave him a warm meal and water, and he was all ok, but dang that sure made me mad at myself.
