How Do I Prevent Fleas, Ticks And Heartworm?

Small parasites can lead to big problems for your pet that are difficult to treat. So when it comes to fleas, ticks and heartworm, it’s important to prevent them altogether.


Fleas are small brown parasitic insects that infest the coat and skin of your pet. Many people think fleas are just an irritation but, if left untreated, they can be fatal to your pet.

Fleas will cause skin disease, tapeworm infection and anaemia in some dogs, especially young puppies.They also transmit harmful bacteria to your cat.
If your pet has fleas, see your local Greencross Vets to discuss what possible treatments –which could include spot-on treatments, chews, tablets,collars or sprays – will best suit your pet. Also speak to your vet about treating your pet’s living environment.

Paralysis Ticks

Paralysis Ticks are small, round-looking parasites that burrow into your pet’s skin to feed and breed. While doing so, they can inject a toxin that affects all muscles until they become completely paralysed.
Paralysis ticks cause progressive paralysis in the muscles, which requires anti-toxin treatment and dogs can die from this toxin.
There is no one-stop-shop prevention method, however tick collars, top-spots, chew tablets and spray products will all reduce the likelihood of a tick latching onto your dog.  Cats are also susceptible to the paralysis tick and there are treatments also available as there is for dogs. No treatments are 100% effective and you must conduct a thorough daily tick search of your pet. To learn how to search your cat for ticks, visit your local Greencross Vets .


Heartworm is a parasite that is transmitted by mosquitos and infects both cats and dogs. The parasite matures in the pet’s organs for six months, becomes a worm, and then migrates to the heart and the blood vessels of the lungs.
Heartworms live in the dog’s heart and physically damage it. They also clog the vessels leading from the heart.
For dogs, there are almost no signs of heartworm until heart failure. Not only is this condition highly fatal, but treatment for cats and dogs can be complex and expensive – so prevention is key.
If the dog already has been suffering from damage to the heart, lungs and other organs, the body may not be able to tolerate coping with the dead adult worms once medication is given.
For dogs, monthly chewable tablets and top-spot treatments are available. However, the most effective prevention method is to take your dog to Greencross Vets for yearly injections. For cats, monthly tablets and top-spot treatments are also available.
Your local Greencross Vets  are able to advise you on the best possible treatment for parasites affecting your pets.
