Internal Medicine

The Internal Medicine service is concerned with diagnosing complex medical diseases of the internal body systems, such as those affecting the heart, lungs, stomach, liver, kidneys, blood and hormones.

In the Internal Medicine Service we specialise in the investigation of complex medical problems. The combination of an experienced and expert team, and sophisticated diagnostic equipment, places us in the best possible position to diagnose and treat a wide range of disorders in dogs and cats. We regularly investigate such conditions as: vomiting, diarrhoea or weight loss; hormonal problems such as diabetes; bleeding; lung disease; cancer and heritable disease. All of these are non-specific signs, common to a range of illnesses.

Because many of our patients have complicated problems that can be difficult to diagnose or treat, they often require a period of hospitalisation to allow a full investigation to be made. We understand that this can be a distressing time for owners and we try to reduce the stress as much as possible by communicating our findings and discussing progress on a daily basis.

We are also very aware of the individual needs of cats and therefore we have invested extensively in feline-only facilities, including a 20-unit inpatient ward for their comfort and security.
We aim to apply and develop non-invasive techniques whenever possible and we have extensive experience in the use of interventional radiology. This method of guiding needles and catheters allows us to treat many conditions non-surgically, thus reducing physical trauma, risk of infection and improving recovery time.

Our Internal Medicine Team works with Specialists from other disciplines to ensure the highest possible level of care.

The team also run a Respiratory Clinic for vets to refer to, for more information please click here.

The dangers of 'Foreign Bodies'.

A ‘foreign body’ is something that gets stuck inside your dog or cat that shouldn’t be there. Something they may have picked up on a walk, or something they have chewed and swallowed or breathed in that gets lodged where it shouldn’t.

The signs that this may have happened include:

Regurgitation or vomiting; this can happen when something gets stuck in the gut, for example this large piece of bone and in another a kebab stick that got stuck in a dog’s oesophagus (the tube between the mouth and stomach) or stuck in the intestines or stomach like this battery and toy that were removed from dogs.


Sneezing and discharge from the nose for example due to a grass seed which we removed from a dog that inhaled it on a walk or a twig that was endoscopically removed from a nose.

Coughing when it occurs suddenly can occasionally be due to something is stuck in their airways like in their windpipe or in this case a wheat head in this dog’s lower airway. If your dog starts coughing after being in the field, a foreign body into the nose is very likely.

Early diagnosis of these foreign bodies allows us to remove them more easily using an endoscope – a long tube with a camera and forceps as this is less invasive than surgery.

Here is a scan of a toy found inside a dog, as well as the endoscope camera photo and the toy removed!

We can diagnose and find these objects using a variety of methods including scans and x-rays such as these radiographs, a CT scan or ultrasound or visually with the endoscope.

Our internal medicine team use different techniques, types and sizes of endoscopes depending on where the object is found. These include rhinoscopy (into their nose), bronchoscopy (into their airways), oesophagoscopy (into their oesophagus) and gastroscopy (into their stomach)!

By using these techniques, we have been able to remove all sorts of objects you can see in the photos. If these objects are left inside then then can migrate around your pet’s body and cause all sorts of problems such as abscesses, so the earlier you can identify this and go to your vet the better chances of removal and a quick recovery.

If you are worried your dog or cat has a problem due to an ingested or inhaled foreign body then please contact your vet immediately to discuss possible specialist referral.
