My breeder has contacted me to say that I can no longer collect my puppy tomorrow as she has diarrhoea. I've been told that the diarrhoea has been caused by the pups feeding off the mum after they had been fully weaned and had not had any of her milk for over two weeks. Could this have caused the diarrhoea. I've googled it and can't seem to find an answer as to whether this could be the cause. Reading all of the information available regarding diarrhoea in puppies has made me concerned that the diarrhoea could be caused by something else. Any advice would be greatly appreciated.
