Not sure why you're so hung up on dogs or 2 months. The thread still shows up in searches and you're clearly getting updates on it.
Unless there's some evidence to suggest the information in this thread is now obsolete, there's no reason not to respond.
@esteeyou made a claim and provided evidence. Unless there's better evidence to the contrary it's reasonable to accept the claim. My children sometimes still respond to arguments with, "Nuh uh." I generally expect more from adults.
