Ive seen it a few times, make sure your breeder knows so they will quit breeding those parents! Look up more info but I know of a few people that made special soft diets and fed in raised bowls. Raised bowls will help her eat easier and keep it down-if I find my old info I will post it for you. There is hope for her and will send prayers your way
I should of read better-glad to see someone has already posted the feeding info to you, Ive seen this work and the puppies did outgrow it-its a little work but very well worth it!
