EVDS are users and suppliers of quality equine dental instruments and tools.

As horse owning professionals being privileged to work in this industry, we care – a lot!

Through walking our talk in the EVDS Vet Clinic, using cutting edge technology and dental equipment such as the PowerFloat, Terafloat, Clear View dental scopes, luxators, forceps, spreaders, fulcrums, elevators, blades, discs, burrs etc every day, we are well positioned to be able to confidently offer a large variety of our preferred equine dental instruments and diagnostic tools to our veterinary colleagues.

As a functioning equine vet practice, with access to the above instruments, we are able to co-ordinate and conduct post graduate teaching workshops for veterinarians in the field of equine dentistry. From horse handling, sedation, nerve blocks, clinical exam, basic oral examination to wolf teeth and canine teeth, premolar and molar teeth, caps, gums (periodontal disease), tooth extraction, correct use and maintenance of equipment etc, we pride ourselves on sending our attendees home competent and confident! In these wet labs events, we have experts from our country, and international at times, come in to teach the post graduate material.


PLUS, each 4-5 years, we consolidate the changes and improvements in the equine dental world and host the Toothfest International Conference, scheduled to run again in 2027.

Dr Oliver Liyou


Dr Oliver graduated from Uni of Qld in 1993 and is the principle veterinarian and business owner of EVDS which he founded in 2002. Having grown up around horses, Dr Liyou has a passion for helping owners to help their horses and enjoys all equine vet work – despite focussing on dentistry.

Since 2002, Oliver has co-ordinated and hosted equine dentistry training workshops for equine vets from all over the world. He has authored several scientific papers and lectured on equine dentistry in most states of Australia, at AVA, AEVA and Aust College Science Week Functions, to vets in China, along with writing many articles for horse magazines to raise awareness of welfare in horses.

Oliver has co-designed many equine dental instruments including the Porta-Safe-Stock trailer, which has been supplied to vets in all states of Australia. He developed his own brand of dental instruments and launched the EVDS webstore in 2005 to service the need for quality equine vet dentistry tools in Australia and New Zealand.

Oliver loves his work but also loves spending time with family and friends, watching rugby league, playing with his horses, boating and most things outdoors and fun.

Matthew Walsh

Grounds Keeper/Stable Hand

Matt joined EVDS at the beginning of 2020 as our Groundskeeper and Stablehand. He much prefers being outside in the fresh air, so enjoys the freedom and challenge of working at EVDS, always looking for ways to make the property look and perform better.


Matt and his partner have three sons, and a granddaughter. He takes great pride in maintaining the grounds of EVDS, always ensuring our clients arrive to a beautifully presented property. 


Chris Spry

Powerfloat Fabricator

Chris was first introduced to EVDS when he installed air-conditioning into Oliver’s house. He and Oliver got to talking about Powerfloats and Chris’s mechanical mind along with his “mad scientist” nature was drawn to the challenge of working out how to service/repair and solve the problems that others had put into the “too hard basket”!

He implemented the “7 day turnaround” for Powerfloat repairs and also developed a unique conversion system for the old style 14v Powerfloat drills so that they can interchange shafts. Chris’s favourite mantra is “There is always a way!”


Whilst not working, Chris enjoys boating, flying, surfing, camping and dancing.
