Our team of researchers of the Clinic of Animal Reproduction, Freie Universität Berlin, Germany, works on vaginal temperature measurement in dairy cows and dogs with the Anipills.
They are validating the use of the Anipills as an ingestible temperature logger in dogs, as well. This approach would allow non-invasive core temperature measurement for a variety of interesting applications (e.g. birth prediction, force due to training/exercise, indisposition).
Studies are still in progress but preliminary results are very promising
