Dogs go into heat around every six months, but it's not set in stone. Give Naughty some more time, but if she hasn't gone into heat in another few weeks, have her seen by a vet. As an aside, I would make this her last litter. Dogs who are around six and older should never be bred. I would have her spayed after she weans this litter. Best of luck.
