ive given boiled rice & chicken to my 11 week old pup, she had runs... would they be healthy eating this long term ,or is it a short term thing , any advice please ??

Pretty sure it could only be a short term thing. Your dog needs a lot more than just chicken and rice for a start I think you would need quite a lot of supplements and other vitamins and minerals but dont quote me on this, hopefully some one else will be along shortly to help you, if not ask the vet they will be able to tell you
