Roundworms are most likely the kind of worms dogs get most. And there are several things to keep in mind, to prevent your dog from getting them:
- Don't let your dog eat wild animals or rodents
- Don't let your dog eat feces
- Always clean up after your dog's feces
- This one's hard, since dog's are constantly sniffing the ground, but try as much as possible to keep your dog's nose off the ground. So they can't pick up anything that could potentially give them worms.
