Check its mouth for teeth. If it doesn't have teeth it can't eat dog food yet. This indicates the dog is younger than four weeks. If it has some teeth but not the full set, it can eat chicken broth and baby rice cereal. This is not a good substitute for mother's milk but might keep the dog alive until vet care can be obtained. As a papillon breeder, I am saddened and apalled that someone might sell a puppy before it was 8 weeks old. Papillons will nurse until 8 or 9 weeks. At 4 weeks they begin to get teeth and start to want more solid foods. By 6 weeks they can eat softened puppy kibble. If the puppy won't eat or drink or if you think it is under 6 weeks old you need to consult a vet immediately. Some illnesses such as parvo will cause loss of appetite and are deadly to puppies under 6 months. Please seek vet care ASAP.
