As a dog owner, you may be horrified to learn that your canine friend may love to lick, eat or roll in chicken poop. However, it could be harmful to your dog as chicken excrement can contain worms and salmonella which can make your pooch sick. The risk is low and will depend on whether the chickens are sick or carrying parasites or diseases, but it’s important to try and discourage your dog from eating chicken poop where possible. The most effective way to stop diseases from being passed between chickens and dogs is to keep their enclosures separate, clean and tidy. Adding pineapple to your chickens’ diet makes their excrement taste bad for dogs, which could stop your pooch from eating it again.
