Yes. That's correct. Your dog is rolling on worms. And sometimes even eating the tasty earthwormy morsels. They'll dig holes in the yard while on 'hunting expeditions' for earthworms. They know the squirmy, lubricated brown beasts are out more often after a good rain. And, yes, your dog even knows that it bothers you (from all the crazy noises you're making) - and doesn't really care.
Ever think your dog smells 'earthy'? Think your dog is just scratching his back on the grass? Yea right, try, more like, rolling on worms; preferably, dead, squishy, messy worms.
There are conflicting reports if earthworms are harmful for dogs to eat...so, our philosophy is if we don't know if it harms, the answer is 'no, no'. Some people report that earthworms digest bacteria that could harm our dogs. Others report their dogs often eat worms, with no issues. Here, we don't want to find out.
How do you get your dog to stop rolling on worms? While your dog is obviously hunting or trying to roll, clap your hands or make a loud 'psst' noise to distract them from their worm hunting, eating, and or rolling. Replace the behavior with a toy and try to actively engage the dog in a game of fetch or play to distract them from their earthy desire.
Besides, we're sure you really don't want to get a face full of 'worm burp' later on, or let your furry kids on the couch if they have smashed earthworm guts on their fur.
