Your puppy’s health is no doubt a top priority, so you’ll want to keep parasite prevention on your radar. Here’s how to keep your puppy safe from fleas, ticks and worms.

Protect your puppy from parasites

Taking a proactive approach to your puppy’s parasite protection is the best way to ensure they stay healthy. Because they’re only small, and their immune systems aren’t as strong as an adult dog, you should be aware of the right treatments for them. Use our Flea, Tick and Worm Treatment Finder to understand which products on the market are suitable for them at this stage and will keep them safe from fleas, ticks and worms all year round.

How to protect your puppy from worms

Intestinal worms

Puppies can be susceptible to intestinal worms, such as roundworms, hookworms, whipworms and tapeworms, which can all cause serious illness. Once you’ve brought your puppy home, you’ll need to start protecting them from intestinal worms. One option is with a tablet every two weeks until they’re three months old. That said, they do have minimum weight ranges, so be sure to check with your local Greencross Vets if you are unsure. Then, every month until they’re six months old. At this point, you’ll choose a product they can take into adulthood – the frequency will depend on the product you choose.


Heartworm can be very serious for dogs. They are transferred via mosquitos and can be fatal, so it’s essential that you cover this off in your treatment. Visit your local Greencross Vets to discuss a heartworm injection. You can also find topical treatments for puppies at Petbarn that will keep them safe from heartworm. Just be sure that your puppy fits within the minimum weight requirements. If you need any guidance, don’t hesitate to ask your local Petbarn team member. Oral tablets and chews are also available.

How to protect your puppy from fleas

For the health of your puppy (and your family), it’s essential that you don’t slip up with flea prevention. Fleas are a parasite that can quickly snowball into an infestation in your home. Plus, when puppies are in their infantile stage, fleas can cause severe anaemia.

When they’re at the puppy stage, keep them safe from fleas with a treatment that suits their age and weight requirements. This could be in the form of a topical (spot-on) treatment that you apply between their shoulder blades or a tablet. If you’re unsure, just chat to your local Petbarn team member, who can help you find the right one. It’s essential to have your puppy on flea medication all year round.

How to protect your puppy from ticks

Though the risk of ticks is greater in summer, the reality is that they are a year-round threat. Ticks can be very dangerous to puppies. Causing paralysis, if left untreated, ticks will be fatal. You’ll likely treat your puppy with a monthly chewable tablet or a fortnightly spot-on treatment between the shoulder blades, just be sure that your puppy fits within the minimum age and weight restrictions on the packet.

Important to note

You can find parasite prevention medications that cover puppies from more than one of the parasites listed above. Often, products will cover off two forms of parasite protection, but you’ll still need to ensure you’re covered on all parasites. Just be sure the products you choose can be used in tandem – check in with your local Greencross Vets.
No matter their age, cat parasite prevention medications should never be given to a dog.
Humans are at risk of contracting parasites from their pets. Be sure to wash your hands after contact with your dog.

Visit your local Petbarn to find a wide range (including variations for different weights and ages) of all of these products and any advice you may need. Refer to your local Greencross Vets to discuss the right preventative treatments for your puppy, and a treatment plan.
