How common are worms in dogs? - Advanced Animal Care
So they're a little more common than what you would think. And that's why we always recommend that our puppies be dewormed and have fecal exam testing done. And then whenever dogs come in for their annual exams, we also recommend they have fecal testing done, especially if they're not on heartworm prevention and can get them from the ground. If you’re in your yard and you potentially stepped in some dog poop from somewhere else and tracked that into your yard, you could have brought some warm eggs in there with you.
