An eight-year-old boy fell face first in dog mess while playing rugby on a pitch where the animals are banned.
Now his father, Ben Harding, is urging dog owners to stay away from prohibited areas amid fears a child could be seriously harmed by the faeces.
The concerned dad from Blackwood noticed the faeces smeared on the face of his son, Jake, after he had been warming up ready to play an under 9s rugby game at Newbridge RFC on Sunday.
