Our Services.

All Greencross Vet practices offer a comprehensive range of professional veterinary services to cater for all your pet care needs utilising the latest diagnostic equipment.


Getting your pet desexed (neutered or spayed) is essential to their health. All Greencross Vets facilities are completely sterile and use the latest in surgical equipment.


Prevention is the best medicine. Kitten and puppy vaccinations (injections) and adult pet vaccinations prevent disease. Get your pet’s vaccinations up-to-date.

Heartworm Prevention

Heartworm can be hard to detect, but it needn’t be hard to prevent. Greencross Vets recommends year round heartworm prevention. Ask your vet about prevention today.


Greencross Vets offer a range of dentistry services like cat and dog teeth cleaning. Consider us your pet’s veterinarian and dentist combined.


An ultrasound is a painless diagnostic procedure that allows vets to take a closer look at your pet’s health. We only use the latest technology for the most accurate diagnoses.



Greencross Vets clinics are equipped with high-quality radiograph equipment including X-ray machines, automatic processors, and X-ray view equipment.

Clinical Pathology

Clinical pathology allows our vets to analyse and diagnose health conditions. Common laboratory tests include blood tests, urinalysis, faecal tests and biopsy examination.

Laboratory Testing

The latest in-house laboratory equipment allows our vets to perform a range of diagnostic tests to achieve accurate, rapid diagnosis of your pets’ health status.
