If dogs can't talk, then the statement "If a dog says, 'all dogs are liars', then he is lying." is true. So is the same statement saying he's telling the truth. A false hypothesis always leads to a true if-then statement.
Be open minded, IF a dog said "All dog's are liars...", what could be possible? He may be lying when he said that, and some dogs may never lie. Or he may be telling the truth, and all dogs can lie, but not all the time.
Maybe you misheard him, or misinterpreted, and what he meant was all dogs are layers, intending to mean "one how lays". Yeah, that's not a word, but he's a dog and he might be new to proper grammar.
The answer given is just the start of the conversation.

"one how lays"? Hmmm, maybe I'm a dog and don't know how to type.
If dogs could talk, this would simply be the famous Cretan Liar logical paradox, and the truth-value of the dog's statement is indeterminate. If all dogs are liars, then the dog who is speaking must be lying, and there is at least one dog who tells the truth. Suppose that dog to be the one who has just said, :"All dogs are liars." If that statement is true, then the dog making it must also be lying. This leads to an infinite series whereby if the dog is lying he is telling the truth and if he is telling the truth he is lying.
It is a simple teaser guys, why are you trying to make it so complicated? It's a joke!! Get it??
Geeez!!!
Geeez!!!
hmm, u got me.
We got a better one.
If Jaye (LittleGreenMan) and Jay (BadBunnee02) say - frequently - that Braingle is dying and nobody pays any attention to that because they hate us for continuously bringing it up ....;
Does that mean we are lying ???
Or ... (alt logic) ... the fact that none of you will engage in a reasonable - and adult - dialogue on the matter indicate YOU are lying ???
... to yourself .... huh ??
Watch this space.
Jaye & Jay (the BunnyFolk ... still laughing)

One for the kiddies I think!
I don't like the answer, and sorry if I'm just "taking it too seriously". The statement says "if".... which means you suspend all else and assume the statement actually to be true, that the dog said something.
The answer is really... yes, the dog is lying. The truth is that SOME dogs are liars. So this dog is, in fact, lying, when he says ALL dogs are liars. He just happens to be one of the some.

My dog can talk...
I agree this teaser is a joke. That's why we're having fun with it. For geeks like us, the discussion above is what fun looks like. We're not taking it seriously.
Why did the happy man not smile? Because he was not happy after all.
The solution should not negate the premise. If we accept something as true because you say it is for the purpose of the joke, it's not our fault we didn't guess the answer.
It still made me laugh, though!

I guess I am just plain logical, because my first thought was that dogs don't talk.
