Refining Dog Care researcher wins NC3Rs international 3Rs prize
Outstanding published research has been awarded this year’s 3Rs Prize.
The awards are run by the NC3Rs, a leading UK organisation dedicated to replacing, refining and reducing the use of animals in research, and are sponsored by GlaxoSmithKline (GSK).
Joint winner of the prize was the work of Dr Laura Hall, University of Stirling, for improving the technique of oral dosing in dogs. The research, which was conducted with AstraZeneca and funded by BBSRC, was published in the Journal of Pharmacological and Toxicological Methods. It demonstrates that a refined protocol using positive reinforcement training with food rewards, a predictable signal for dosing, and covering the dosing tube in palatable paste during training, minimises stress in the dogs compared to the standard approach, and also has the advantages of allowing researchers to dose the dogs more quickly and efficiently.
Most laboratory dogs in the UK are used for safety testing, and oral dosing is one of the most common procedures used during these tests. Typically, prior to testing of the drugs the dogs are ‘sham’ dosed in order to familiarise the animals with the gavage procedure. The assumption is that this minimises any stress the dogs may subsequently experience. However, this paper provides evidence to show that sham dosing has a negative impact on welfare. This may have implications for sham dosing in other species.
Dr Hall said: “Over 3,500 dogs are used in research and testing in the UK every year, and yet we know little about their welfare or the effect of welfare on the data obtained from their use. I am delighted that the NC3Rs has recognised the importance of this research for the welfare of laboratory housed dogs. We are now building upon our collaboration with AstraZeneca by working with organisations using dogs in the UK to develop further refinements and share best practice.”
The other joint winner describes a 3D model of the embryonic human brain created from stem cells. A highly commended award was also made for a paper describing the development of ‘personalised’ organoids of colorectal cancer derived from the patients’ own tissue.
The NC3Rs is a leading UK organisation dedicated to replacing, refining and reducing the use of animals in research, and the 3Rs Prize is part of its strategy to recognise excellence in science which minimises animal use or improves animal welfare.
Sponsored by GlaxoSmithKline, the international 3Rs Prize is awarded every year to the authors of an original research paper published within the last three years with outstanding scientific or technological potential to replace, reduce or refine the use of animals in research. Applications are judged by an expert Panel. The prize consists of a grant of £18k, plus a personal award of £2k.
Paul-Peter Tak, Senior Vice President of R&D at GSK, said: “At GSK, we’re committed to the care, welfare and treatment of the animals we use in researching and developing new treatments, and we replace, reduce and refine animal studies wherever possible. The NC3Rs is key to supporting advances in the 3Rs and we’re proud to support this prize to encourage innovation in such a critical area.”
Professor Ian Kimber OBE chair of the Prize Panel, said: “The task of the Panel in reaching decisions about the annual NC3Rs prize is always formidable, but this year was more challenging than ever. There were some outstanding nominations describing truly ground-breaking research. On this occasion, for the first time, two awards have been made. The substantial achievements made by these joint winners are very different, and serve to illustrate the breadth of the science that can impact on the 3Rs. The Panel congratulate the winners, and the highly commended awardee, for their remarkable work.”

The National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs) is a leading independent scientific organisation dedicated to replacing, refining and reducing the use of animals in research and testing (the 3Rs). It supports the UK science base by driving and funding innovation and technological developments that minimise the need for animals in research and testing, and lead to improvements in welfare where animals continue to be used. It funds research, supports training and development, and stimulates changes in regulations and practice.
Primarily funded by Government, the NC3Rs is also supported by the charitable and private sectors. It works with scientists in universities and industry in the UK and internationally.
