Question to the Home Office:

To ask the Secretary of State for the Home Department, with reference to her Department's report entitled Annual Statistics of Scientific Procedures on Living Animals Great Britain 2023, published on 11 September 2024, what type of tests comprised the procedures conducted on dogs; and what steps she is taking to (a) reduce and (b) replace the use of dogs for such tests.

69% of procedures of dogs in research are for the safety testing of potential new medicines to protect human health. The legal requirements for these tests are largely harmonised globally to ensure international acceptability of testing and prevent unnecessary duplication. Tests of procedures on dogs predict the safety of conducting the equivalent procedures on humans with up to 96% accuracy.

31% of procedures of dogs in research are for basic and translational research, primarily to discover and develop products to address human and animal diseases.

Research using dogs has been instrumental in the development of medications for use in treatments for cancer, heart disease, diabetes, and genetic disorders.

In March 2023 The National Centre for the 3Rs made its biggest award to date in a single investment (£1.6M) to develop a ‘Virtual Dog’. The project aims to exploit advances in computational approaches and machine learning to ultimately replace their use in chronic toxicity studies.

Where dogs have to be used in science, the Regulator assures that the principles of the 3Rs (Replacement, Reduction and Refinement) are fully applied in all granted licences. These establishments are then subject to rigorous audit by Inspectors for compliance purposes.
