I agree, accident or not... it's still terrible. I'm sure this didn't happen on purpose, well at least pretty sure. People and their causes don't always mean they do what they preach. The dog was old, and had a lot of problems, so maybe it was their way of letting the dog die? But I sure hope not! Doesn't matter though, even if it were an accident, it's still wrong. A lot of "accidents" happen, and the person responsible still has to pay the piper for it. Saying "ooops I'm sorry, it was an accident", doesn't fly for other crimes.
