Dr Ash and the team have been nothing short of amazing with our beloved pets. Dr Ash carried out surgery on our 7year old Rottweiler and the love and care she received was amazing. We also recently had our new kitten desexed and microchipped and again the service was fantastic.

A second chance at life

A big thank you to Dr. Ash and the team for helping me give this little guy a second chance at life. As someone who didn’t grow up around pets, I had no idea what to do when this little one showed up on my back porch in such a poor state. I highly recommend Family Vets Western Sydney to any pet owners looking for a knowledgeable, patient, and caring team!

Why should your pet undergo heartworm prevention with Family Vets?

Heartworm disease is a serious and potentially fatal disease seen in all mainland states of Australia. Dogs are more susceptible to heartworm infestation than cats, and heartworm disease also tends to be more severe in dogs. Adult worms live within the heart and large blood vessels where they can grow to more than 30 cm in length. Heartworm larvae, more commonly called microfilariae, can also be found circulating in an infected dog’s blood.

We understand the potential risks of heartworm and offer a variety of preventative options:
Chews
Topical Treatment
Tablets
Injections

Flexible payment options:

You can trust our team and +40 years of experience!

How is heartworm in dogs spread?

Heartworms are transmitted from one dog to another by mosquitoes, which pick up the tiny microfilariae when they bite an infected dog. The microfilariae develop in the mosquito and are transmitted when the infected mosquito bites another dog. The heartworm larvae then migrate through the dog’s tissues and circulatory system, eventually reaching the heart and lungs where they grow into adult heartworms.

Why is heartworm disease dangerous?

Heartworm may cause no clinical signs in the early stages of infestation, but as the worms grow and mature, they can interfere with the normal circulation of blood. This can result in signs of heart failure, and in some cases may lead to sudden death.

Thankfully, heartworm is very easy to prevent and should form part of your pet health care routine.

If your pet has not been on heartworm prevention we strongly recommend you speak to us about a heartworm test prior to starting a prevention program.

Please contact us or call 02 9622 1200 to discuss the best heartworm prevention program for your pet.
