Guide written by the MyPetScript Team

Why regular worming is important

Regular worming is an important part of keeping your pet healthy. Dogs and cats can pick up intestinal worms from contaminated environments, fleas, raw meat or infected prey. 

Fleas can also play a role in transmitting certain parasites, so it’s important to understand how to manage infestations effectively.

Puppies and kittens often require worming every 2–4 weeks until they are a few months old, while adult dogs and cats are typically treated every 3 months. Outdoor pets or those that hunt may need more frequent treatment depending on risk.

When to contact your vet

Choosing the right wormer depends on your pet’s age, lifestyle and parasite risk. If you are unsure which product is suitable for your pet, speak with your veterinary practice for advice.

Some pets may show changes in behaviour such as restlessness or discomfort when unwell. If your pet is anxious, you can also explore calming products to help support them.
