The Davies Veterinary Specialists Building

Veterinary Internal Medicine Service

The Veterinary Internal Medicine Service at Davies Veterinary Specialists is led by Dr Nat Whitley. He works with our experienced team of physicians, Julien BazelleIan BattersbyKatherine Clarke, Polly FrowdePatricia IbarrolaTheresa McCann and Anna Threlfall to provide a flexible and efficient service covering emergency cases as well as routine consultations.

‘Dr Nat Whitley and Ian Battersby explain the detective work involved in investigating and managing medical diseases. This is illustrated by seeing the investigation of Ace, a German shepherd dog with vomiting and diarrhoea.’


The Veterinary Internal Medicine Service accepts cases for investigation with clinical problems that are not obviously surgical. These can include vomiting, diarrhoea, excessive drinking, malaise, weight loss/weight gain, anaemia and fever. Sometimes, if a case is found to have a non-medical disease and, for example, needs surgery or cancer treatment, it may be transferred to another part of the clinical services team within Davies Veterinary Specialists.

After tests, animals may need to go back home to await results, but some may need to stay in for additional treatment, according to how unwell they are.

The Internal Medicine team are strongly motivated by the ‘detective’ work required to establish a diagnosis and the resulting ability to make animals better, whenever possible.

Nat and the team are happy to discuss cases over the telephone with veterinary colleagues, but are unable to discuss cases with owners prior to a formal consultation.
