Hi We picked up our puppy last night and she's had diarrhoea with blood in through the night and a mucus stool just now. We fed her a couple of small training treats which werent the same as her puppy food she's had from the breeder. Could this be the cause. Would symptoms from diet chanhe appear that fast?

Changes from diet can appear very fast, but if i had to guess she came with this from the breeder. i strongly recommend taking her to the vet today in order to get it treated, it could be a serious gastrointestinal infection as well.
