How Dogs Get Roundworms
- His mother. If your puppy’s mother is infected with roundworms, she may pass them before he’s born. Or he may get them by drinking her milk.
- The environment. Your pup can get roundworms if he eats roundworm eggs that come from another animal’s poop, or if he eats mice or other small animals that are infected.
- Deworm your puppy when he’s young. The best time to start is before he’s 3 weeks old.
- If your dog is a female, treat her before she breeds and again during pregnancy.
- Keep things clean, including the areas where he eats, sleeps, and plays. Throw away his poop properly. Clean up after him in your yard and also in the park. Don’t let your dog use a playground or sandbox as a litterbox.
- Keep your dog away from small, wild animals. They can carry roundworms. Consider keeping him on a leash or in a fenced yard.
- Give your dog drugs to prevent heartworms. Many have ingredients that also prevent roundworms.
- Talk to your doctor about possibly deworming your dog every so often if he’s at high risk of an infection.
