We can investigate and treat cardiovascular and respiratory diseases using our diagnostic facilities. Cardiorespiratory investigations often include thoracic radiographs, fluoroscopy, ECG, echocardiography with spectral colour Doppler imaging and bronchoscopy.

Our facilities include specialised oxygen cages for patients who require intensive care and oxygen supplementation.

Endocrine disorders can present with an array of clinical signs such as increased thirst and drinking (PU/PD), increased appetite (polyphagia), weight gain or loss, alopecia and skin changes. The diagnosis and treatment of some endocrine diseases can be challenging. Our referral clinicians have expertise in the diagnosis and management of a wide range of common and rare endocrine diseases, including Cushing's disease, Diabetes mellitus, thyroid disorders (hyperthyroidism, hypothyroidism), and disorders of electrolyte or mineral regulation (e.g., hypercalcaemia, hypoglycaemia).

We also provide care for critically ill patients with diabetic ketoacidosis.

Problems of the gastrointestinal tract, pancreas, and liver and gallbladder are common in dogs. We investigate these problems using specialised diagnostic procedures such as fluoroscopy for disorders of swallowing and investigation of regurgitation, ultrasound for gastric, intestinal, hepatic, or pancreatic diseases, and endoscopy for investigation of the gastrointestinal tract.

Haematology focuses on diseases of blood cells (red blood cells, white blood cells, blood platelets) such as anaemia, thrombocytopaenia and leukopaenia as well as bleeding disorders. For investigation of bleeding disorders, we have a specialised equipment called the TEG machine (Thromboelastography (TEG) which is a point-of-care diagnostic device used to measure the entire process of blood clot formation, strengthening, and breakdown (fibrinolysis) in real-time.

 We also have an in-house blood bank for dogs and cats in case blood and/or plasma transfusions are needed.

Immune mediated diseases occur when the immune system targets tissue in the body. Affected organ systems include blood cells (immune mediated anaemia, thrombocytopaenia or neutropaenia), joints (immune mediated polyarthritis) or the central nervous system (steroid responsive meningitis arteritis (SRMA), meningoencephalitis of unknown origin (MUO). The diagnosis is established after a thorough workup , including infectious disease testing and imaging, and treatment is targeted at immunosuppression. (link to publications).

Infectious diseases can affect multiple organ systems, including the central nervous system (CNS), and include parasitic, bacterial, viral, fungal and protozoal diseases. At the University of Sydney, we have been conducting extensive research on canine leptospirosis and novel treatment options for feline infectious peritonitis (FIP) in recent years. Our research has led to the development of a new leptospirosis vaccine and has significantly improved outcomes in cats with FIP, which is now considered a treatable disease.

Urology and urogenital conditions involve the urinary system (kidneys, bladder and urethra) as well as the reproductive organs. Renal disease refers specifically to conditions affecting the kidneys, which play a vital role in filtering waste, maintaining hydration, and supporting overall health. Our veterinary team provides diagnosis and care for these conditions to help keep your pet healthy and comfortable.
