"Specifically with the dog nothing has been suggested either way so we can't just assume she "killed a dog" full stop from her "I killed sparky too" line, like she's not a reliable narrator. Is it possible? yeah. Is it likely? sure. Can we definitively say that? nope. We know the dog came out of nowhere, and Agatha "killed it", but we also know Agatha can turn a bug into a bird and other magical shit. We have no idea if sparky was a real dog, a bug, or a full on illusion, or even actually dead since all the characters see is something wrapped in a blanket. Many expect Agatha to be "evil" and she killed a dog to rattle Wanda, but there's definitely enough to piece together to doubt that, so it's not shocking folks think she'll turn out alright."
