You have got to be kidding me.
Don't make this about me, when YOUR story doesn't add up. I am far from perfect, but I would never go so far as to not be able to tell my story the correct way the first time.
You need to take that poor dog to the vet for xrays. If she's not pregnant, obviously she needs to go on a diet. If she is, then the pups should be aborted because you know absolutely nothing about her history.. unless, of course... you've weaved a tangled web of lies for us.
Please listen to the excellent advice that knowledgeable breeders are giving you.
