Question to the Home Office:

To ask the Secretary of State for the Home Department, with reference to the Accredited official statistics, Annual statistics of scientific procedures on living animals, Great Britain 2025, updated on 27 August 2026, Figure 5: Number of experimental procedures involving specially protected species 2025 to 2025, how many of the 1,706 dogs used in scientific procedures for the first time died a) during and b) following completion of the procedures.

Under the Animals (Scientific Procedures) Act 1986, licensed establishments are required to maintain records of the source, use and final disposal of protected animals bred, kept or used at the establishment for regulated activities. These records must be made available to Home Office Inspectors on request.

The Home Office does not centrally collect information identifying the specific establishment or other place at which dogs used in scientific procedures were born, nor does it collect information on all animal deaths during or following experimental procedures.

However, the published statistics record 46 non-recovery procedures involving dogs in 2025. A non-recovery procedure is one carried out under general anaesthesia from which the animal does not recover consciousness. This figure does not represent all deaths that may have occurred as a direct result of regulated procedures.
