Overview
Worming your dog regularly helps protect them, and your family, from harmful parasites. But with so much advice online, it’s easy to feel unsure. So, how often should you worm a dog?
At Pet Health Club, we recommend worming all adult dogs at least every three months. This helps tackle common worms like roundworm and tapeworm and follows guidance from leading experts, including ESCCAP (European Scientific Counsel Companion Animal Parasites). Some dogs need worming more often. If your dog scavenges, eats raw food, mixes closely with other dogs, or lives with young children or vulnerable adults, monthly worming may be the safer choice. Lungworm is another concern, now more common in the UK, and often requires monthly protection using a licensed product.
It's also important to use treatments responsibly. Like many vets, we’re mindful of the potential environmental impact of parasiticides. That’s why our approach is always risk-based and tailored to your pet. Your vet can help you choose an individual schedule that keeps your dog protected, and keeps unnecessary treatments to a minimum.
