My dog used to eat the poo from other dogs when we went to the park. She used to be running around and get it in her mouth and run off somewere else to eat it.. Ughhhh.....
She would never eat her own.
It went on for ages. She even caught some sort of disease from it. In the end i bought a muzzle for her to wear everytime we went to the park. She was not impressed...
But it stopped it from happening.
