How Often Should Puppies Be Wormed?
Bringing home a new puppy is exciting, but it also comes with plenty of questions about keeping them healthy. One of the most important parts of early preventative care is worming. Puppies are particularly vulnerable to intestinal worms, and regular treatment during the first months of life helps protect both their wellbeing and the health of other pets and people in the home.
In this practical guide, we explain how often puppies should be wormed, why early treatment matters, what signs to look out for, and when to speak to your veterinary surgeon. If you are looking for parasite prevention products, you can also browse our flea, tick and worming collection or view our wider dog health products.

Why do puppies need worming so early?
Puppies can pick up worms very early in life, sometimes before they are even born. Some worms can pass from the mother to her puppies during pregnancy or through her milk after birth. This means that even very young puppies that seem otherwise healthy may already have a worm burden.
The most common intestinal worms seen in puppies in the UK are roundworms and, less commonly, tapeworms. Roundworms are especially common in young dogs. In larger numbers, they can affect growth, digestion, and general health. Good parasite control from the beginning gives puppies the best start and helps reduce contamination in the home and garden.
How often should puppies be wormed?
In the UK, puppies are usually wormed:
- Every 2 weeks from 2 weeks of age until 12 weeks old
- Then monthly from 12 weeks until 6 months old
After 6 months of age, the most suitable routine depends on your dog’s lifestyle, the products being used, and your vet’s advice. Many adult dogs are then wormed every 1 to 3 months, but this varies depending on risk factors such as scavenging, hunting, raw feeding, and living with young children or vulnerable adults.
Because different worming products have different licences and dosing schedules, it is always best to check the packaging carefully and follow your veterinary surgeon’s guidance. If you are ordering treatment online, make sure you choose a product suitable for your puppy’s age and weight. If you are unsure, our team can help point you in the right direction through our contact page.
A simple puppy worming schedule
Many owners find it helpful to follow a simple timeline:
- 2 weeks old – first worming treatment
- 4 weeks old – repeat treatment
- 6 weeks old – repeat treatment
- 8 weeks old – repeat treatment
- 10 weeks old – repeat treatment
- 12 weeks old – repeat treatment
- Then every month until 6 months old
If your breeder has already started worming, ask for a written record of what was given and when. This is particularly useful when you register your puppy with your vet or when planning future treatment. If your puppy’s worming history is unclear, your veterinary surgeon can advise you on the safest next steps.
What worms do puppies commonly get?
Roundworms
Roundworms are the most common worms seen in puppies. They live in the intestines and can sometimes be visible in the faeces or vomit, often looking a little like spaghetti. Puppies can become infected before birth or through their mother’s milk.
Tapeworms
Tapeworms are less common in very young puppies but can become a problem if a puppy swallows fleas during grooming. This is one reason flea control and worm control often go hand in hand. You can explore suitable options in our dog flea and worming products range.
Other parasites
Depending on your puppy’s lifestyle, travel history, and environment, your vet may also discuss protection against other internal parasites. Not all wormers treat every type of worm, so it is important to use the right product for your puppy’s needs.
Signs your puppy may have worms
Some puppies with worms show no obvious signs at all, which is why routine worming is so important. Others may develop symptoms such as:
- A bloated or pot-bellied appearance
- Diarrhoea
- Vomiting
- Poor growth or slow weight gain
- A dull coat
- Visible worms in faeces or vomit
- Dragging their bottom along the floor
These signs are not specific to worms and can happen with other health problems too. If your puppy has ongoing digestive upset, seems lethargic, is not eating normally, or you are worried for any reason, contact your veterinary surgeon for advice.
Why regular worming matters
Worming is not just about treating visible worms. Regular treatment helps prevent heavy infestations that may affect your puppy’s growth and comfort. It also reduces the spread of worm eggs in the environment.
Some worms can be passed to people, especially through accidental contact with contaminated soil or dog faeces. Good hygiene and prompt removal of faeces from the garden are sensible steps for every household, particularly those with children.
How to choose the right worming product
There are several types of worming treatments available for puppies, including liquids, granules, tablets, and spot-on products. The best choice depends on your puppy’s age, weight, and how easy they are to medicate.
When choosing a wormer, consider:
- Your puppy’s exact age and body weight
- Which worms the product treats
- Whether your puppy also needs flea control
- Whether the product is prescription-only or available without a prescription
- How easy the treatment will be to give correctly
If your vet has prescribed a treatment, you can order it safely through our prescription medicines section. If you are new to ordering online, our guide on how to order a prescription medicine and our prescription FAQs may be helpful.
Tips for giving worming treatment to puppies
Giving medication to a wriggly puppy is not always easy, but a few simple steps can help:
- Weigh your puppy accurately before dosing
- Follow the product instructions carefully
- Complete the full schedule rather than stopping after one dose
- Ask your vet or pharmacist if you are unsure how to give the treatment
- Record each treatment date so you do not miss the next dose
Never guess the dose or use a product intended for another species or age group. Responsible medication use is important, especially in very young animals.
What about flea treatment at the same time?
Fleas and worms are often linked, especially when it comes to tapeworms. If your puppy has fleas, your vet may recommend treating both problems together. This can help break the cycle of reinfection and keep your puppy more comfortable.
Many owners choose to put a reminder system in place for regular parasite control. If your puppy is also settling into a feeding routine, training plan, and general healthcare schedule, keeping worming and flea treatment dates in one place can make life much easier.
When should you contact your veterinary surgeon?
You should speak to your vet if:
- Your puppy has diarrhoea, vomiting, or poor appetite
- You can see worms in their vomit or faeces
- Your puppy is losing weight or not growing well
- You are unsure which worming product is suitable
- Your puppy misses doses or vomits soon after treatment
- You have concerns about side effects
Young puppies can become unwell quickly, so it is always better to ask for advice sooner rather than later if something does not seem right.
Supporting your puppy’s overall wellbeing
Worming is one important part of a wider preventative healthcare plan. Alongside parasite control, your puppy will also need vaccinations, good nutrition, regular weight checks, and routine veterinary care. As they grow, some owners also choose to support digestion, joints, skin, or general wellbeing with carefully selected products. You can explore our dog supplements and premium supplements if your vet feels they may be appropriate.
Conclusion
As a general guide, puppies should usually be wormed every 2 weeks from 2 weeks of age until 12 weeks old, and then monthly until 6 months old. This early routine helps protect them during a stage when they are especially vulnerable to intestinal worms. From 6 months onwards, your veterinary surgeon can help you decide on the most suitable ongoing parasite prevention plan based on your dog’s age, lifestyle, and risk factors.
Regular worming, good hygiene, and choosing the right products for your puppy’s age and weight all play an important part in keeping them healthy.
