Internal Medicine


There may be occasions when the first diagnosis of your pet’s symptoms reveals that a number of complex medical problems may exist. Should this happen, our Internal Medicine team specialises in investigating further, to make sure that no causes of the pet’s condition are overlooked.

Precise understanding of your pet’s ailment

Southfields’ board-certified Internal Medicine Specialists are licensed veterinarians who have undertaken intensive, additional training in understanding how your pet’s internal body systems function. Their role is to diagnose and treat any serious diseases that may be affecting the health of those systems. They have greater knowledge and experience in the management of complicated and common medical conditions in dogs and cats. They are also trained in using advanced diagnostic and therapeutic equipment, such as endoscopy.

Ensuring better outcomes

Because better ongoing health care enables pets to enjoy longer lives, older pets may develop multiple disease states that require sensitive, experienced, and informed management. Our Internal Medicine Specialists understand these requirements, and are also especially prepared to care for pets that may be facing multiple health problems at the same time.

A referral to our Internal Medicine team will involve an initial consultation where we will examine your pet and take a full medical history. Typically, a patient will then be admitted for further tests, for example blood tests, x-rays, ultrasound scans or endoscopy. Following these tests, patients are usually discharged to await results.

We’ll look into conditions presenting with symptoms such as vomiting, diarrhoea, excessive thirst, malaise, weight loss or gain, anaemia and fever. Once we’ve identified the cause of your pet’s symptoms, we’ll develop an individual treatment plan tailored to their specific needs. If diagnosis reveals a non-medical disease we will work with our colleagues in the relevant team at Southfields to arrange the appropriate treatment.

Supporting referring vets

Our dedicated specialist-led Internal Medicine team has extensive experience in acute, chronic and urgent medical problems. We take an inclusive multi-disciplinary approach and work closely with our colleagues in other disciplines on challenging cases to ensure the most complete care.

Many new cases and emergencies referred to Southfields are seen first by the Internal Medicine team. Our continuity of care means referring veterinary surgeons, our patients and their owners all benefit from having access to a member of the specialist team, whenever needed. Our team welcomes calls for advice on specific patients and cases, even if no referral is required.
