London - Animal testing on dogs is on the rise, with a 16 percent increase in the number of experiments involving them last year.
However, overall scientific testing on live animals has fallen to its lowest level since 2007.
The dogs, mainly beagles, have been used to test procedures for human respiratory problems and to see how parts of the body such as the musculoskeletal system work, among other studies.
In more than 2 000 cases, the dogs were used to test whether or not repeated doses of drugs were toxic.
Researchers carried out 3.52 million procedures on living animals in England, Scotland and Wales last year, down seven percent from 2017, according to data from the Home Office, which is responsible for regulating animal experiments.
