    Have you put food coloring in the tank to see if the flapper isn't 100% tight. Even with a new flapper the seat that it sets on might ha e small crack or built up not letting the flapper to seat properly.

    Agree with servicefitter - place one of those dye tablets in while the tank is really calm and you will easily see where the leak is. I had one once where the porcelain itself had a flaw and the flapper valve wasn't the issue. A little bit of plumber's putty solved that one.

    I had a customer tell me he had changed the flapper and flush valve, he changed the flapper twice. He removed the tank to change out the flush valve. I told him all I would be able to do is the same thing he did. Maybe a bad flush valve. Idk. But thinking back, I don't like korky flappers, I think they suck. I think if I would have known at the time I would have changed it to a standard universal flapper.

    I have had the same problem, check the flush valve, I am finding more and more, with a horizontal crack just under the flapper seat.

    You don't even neeed dye to tell you're loosing water. Maybe your chain is just a tiny bit too short?

    The sealing surface where the flapper sits when closed can wear out. The term is “wire drawing”. Just the same as tires on the car wear out, your flush assembly can wear out too. If it’s a 1 piece toilet that’s a big job. If you’re into that toilet, then sure. I’d recommend a gerber. They are American made and actually really solid. Unless you want to pull a toilet and hunt down the bottom of the flush assembly probably not worth it.

    Or is your fill valve defective and sending water down the over flow pipe ?

    Maybe the dog is drinking out of the bowl and flushed when empty
