They can actually get worms from fleas too, not just other dog feces. A dog should be wormed every 3 months is what they say, but I (like Jeanie K) have never wormed mine after the puppy worming and have never had worms (knock on wood). Since worming is so safe though I really do think you should do it at least once a year, if it's not covered in the heartworm preventative you use. |
