We have a 6-mo. old lab-mix that we adopted 2.5 mo. ago from a lab rescue group. He loves to eat poop! He doesn't care what it is. He eats horse poop, deer poop, rabbit poop, and his own poop. Should I be worried about this habit? He gets plenty of food and treats from us throughout the day (2.5-3 cups of food a day and lots of treats (bones, biscuits, chicken, chewies, etc.).
It is normal, but you should also try to stop him doing it because of parasites and other nasties that could be on the poop. That said, it is really not an easy habit to break because it is self rewarding. Where is he when this is happening? off leash I assume?
