What's the best way to deworm a dog?

Worms aren’t just gross—they can sap your dog’s energy, cause digestive issues, and even spread to humans. A playful pup rolling in grass or sniffing around a community garden might pick up roundworm eggs, while fleas (common in warmer European climates) can carry tapeworms. That’s why staying on top of deworming isn’t just about comfort—it’s critical for their health.

Start with a vet’s guidance. Over-the-counter meds work for some cases, but your vet will tailor the approach. Puppies, for example, often need deworming every two weeks until 12 weeks old, then monthly until six months. Adult dogs usually get treated every 3–6 months, though outdoor dogs or those in rural areas (think farms in France or hiking trails in Colorado) might need more frequent care.

Pills aren’t the only option. Chewable tablets taste like treats—great for dogs that spit out pills. Topical solutions, applied to the skin, work well for wriggly pups. In some countries, like Germany, vets may recommend injectables for high-risk cases, but these require professional administration to avoid mistakes.

Timing matters, and so do local rules. In parts of Scandinavia, breeders must provide proof of deworming before selling a puppy—skipping this can lead to fines. Even in places with looser laws, shelters and boarding facilities often demand up-to-date records. Imagine showing up for a family trip and being turned away because your dog’s deworming certificate is expired.

Watch for red flags. Weight loss, scooting, or visible worms in feces are clear signs, but subtler clues like a dull coat or lethargy matter too. If you spot these, don’t wait for the next scheduled dose—call your vet. Catching a heavy infestation early can prevent long-term damage, especially in small breeds.

Make it a routine. Pair deworming with other monthly tasks, like flea prevention or nail trims. Keep a calendar or set phone reminders—consistency beats occasional efforts. And remember, deworming protects more than your dog. Kids playing with pups on the living room floor are at risk of zoonotic worms, so staying on schedule keeps the whole household safe.

Talk to your vet about the best products for your dog’s lifestyle. A city-dwelling Chihuahua needs a different plan than a Border Collie herding sheep in the Scottish Highlands. By staying proactive and following local guidelines, you’ll keep those tail wags strong and your home free of unwanted guests.
