Spaniel-beagle puppies are first in the world born using IVF
Spaniel-beagle cross-bred puppies are the first in the world successfully born to a surrogate mother after years of failed attempts.
In vitro fertilisation (IVF) treatment was used, which is similar to that used in human fertility clinics.
Past problems with freezing the embryos were overcome and they were successfully implanted in the dog. The resulting litter of seven puppies has three sets of parents.
The advancements will now be used to help conserve endangered breeds, such as the African wild dog, and could also be used in the study of inherited diseases, both in dogs and humans. It opens up the possibility that genes causing disease in our pets could be identified and fixed.
All but one of the puppies so far have been found new homes.
