Facilities at Mercer and Hughes Vets

We offer a range of in-house diagnostic treatments, facilities and equipment across our various surgeries. This allows us to provide you and your pet with access to a wide range of treatments without the need to travel afar.

Being able to run a multitude of tests on site means we are able to get quick results and support faster diagnosis.

Our Services

Treatment generally requires a combination of a number of services listed here and many more too numerous to mention. Here are some of the main treatments we offer…


We carry out a broad range of surgeries at our practice, from routine spaying and castration to more intricate operations.

Among our experienced team we have surgeons who have attained post-graduate certificates in veterinary cardiology and we take referrals from other practices in the area.

With the support of our highly qualified and experienced nurses, we are able to carry out complex cardiac diagnostic procedures and cardiothoracic surgery.

Blood Sampling

A blood sample will help in diagnosis of many conditions, our ‘on the premises’ laboratory helps to speed up the results process.

Dietary and Medicine Advice

A healthy diet’s as essential to the well-being of your pet as it is to you and we will always be happy to advise on maintaining a balanced diet to maintain optimum health.

Many of our patients are on life long medication which we also provide biannual medication checks. This is to ensure they are under our vet’s supervised care.

In some cases written prescriptions can be used to purchase medication via certified/accredited online veterinary pharmacies, in this instance these 6 monthly checks are even more vital to maintaining the health of your pets.

Electrocardiographs (ECG)

To diagnose certain conditions and to understand how your pet’s heart is working we are able to produce electrocardiographs which show a picture of the electrical activity of the heart.


All our surgeries are equipped with X-ray equipment which is used to take a look at your animal’s insides to detect bone fractures, organ condition and the presence of foreign bodies such as coins, balls, stones etc.


For a long and healthy life, your animals should be vaccinated against common diseases.

Nail Clipping

Maintaining nails and claws not only helps your animal’s comfort but also ensures safer handling.

Blood Pressure Monitoring

Assessing an animal’s blood pressure is useful as a measure of their general health and also helps to diagnose certain conditions, particularly in cats.
It is also helpful to monitor a patient’s blood pressure whilst it is under general anaesthesia.


Dental care is an important part of small animal practice.
Each surgery has excellent dentistry facilities enabling us to provide a wide range of dental health care from routine descaling through to more complicated dental procedures including extractions.
Our staff will be pleased to advise you regarding your pet’s dental health.

Urine Sampling

Urine samples will help in diagnosis of many conditions, our ‘on the premises’ laboratory helps to speed up the results process.

Endoscopy Exploration

Endoscopy involves using a fibre optic light and camera to visualise an area inside the body that would normally be difficult to see, for example inside the bowel or lungs.

It is also sometimes possible to use the endoscope to take small pieces of tissue (a biopsy) from these areas, which can be extremely helpful for making a diagnosis.

Ultrasound Scans

Ultrasound creates a ‘real-time’ picture of an animal’s organs and enables us to detect foreign objects, unusual shapes or pregnancy within an animal.

In An Emergency

If your pet has an emergency during our normal opening hours, please call the practice and we will advise you what to do next.

We have partnered with Vets Now in Witham for our out-of-hours care. Vets Now is the pet equivalent of an accident and emergency service, dedicated to providing pets with access to a vet out of hours.

It’s all they do. You can still call any of our numbers and you will be given directions on how to call them, or you can call them directly on 01376 530759.
Based at Witham, their vets and vet nurses are specially trained to deal with pet emergencies.

Because they don’t work during the day, they’ll be up and ready to see your pet at the time you need them.
