Thanks for commenting on my blog am glad. Firstly, Nigerian local breed is commonly called mongrel which was the name given to it by the british years back. But mongrel is not a cool name as it means insult. So we prefer to call it Nigerian local breed dog.
Secondly, there is something called pathognomonic signs in medicine which means that once you see those signs, it obviously that it the particular disease. Parvo viral enteritis usually have pathognomonic sign of very foul smelling diarrhoea. It very obvious. So i don't need to go too far to make diagnosis. @greenrun
