The U.S. Food and Drug Administration is committed to animal welfare in research by reducing, replacing and/or refining the use of animals in research, whenever possible.
The aim is this: by doing a single study to help establish a non-animal based model, it can potentially replace much of the need to use dogs in future trials with new informatics tools. The goal is to do one single study involving a small number of dogs—where the dogs will only be subject to minimally invasive blood sampling, and adopted as pets at the completion of the short trial—to eliminate the need for the use of dogs in certain types of future studies, some where they might have been euthanized.
