Did you change her food from what the breeder gave her? What did they use, was she on Wellbeloved when you got her? Maybe the food doesn't suit her. I would put her onto chicken and rice for a few days to settle her stomach down then gradually add an alternative kibble until she is onto a new food. Try an alternative good quality dried food like Burns or Barking Heads. Maybe others here can suggest other food that their dogs do well on. Flo is on Wellbeloved with a little wet food (Nature Diet) mashed in. Maybe get her checked by the vet if the problem persists for 2 or 3 days once on chicken and rice. Also lay off any treats that could be upsetting her stomach for the moment.
