Here's the post (had 14 likes):
"For those of you who knew Darcy, the goofy pitt mix, I appreciate yalls prayers and concerns. She fought hard through the surgery to remove the tumor a couple days ago but passed away last night after a short seizure. Again, thank y'all for the prayers."

I mean, I get their sentiment. People appreciate him thanking them for their prayers, but the point of the post is to notify people his dog is dead. Idk. It's a rhetorical question. Just make no sense to me....
