She's a beauty!
If you haven't already you need to take her in for a well check with the vet - this is pretty standard in most breeders' contracts. If you find an issue and wait, then per the contract the breeder won't be responsible. Sneezing may just be environmental, but it could also be an underlying viral infection.
When you say soft feces are you talking about diarrhea, or mushy stools, or just not hard formed? Are you feeding the same food as her breeder was? Any sudden change in diet can upset the tummy and cause diarrhea, so any switch to a new food should be made gradually.
