Embryos Were Implanted into Domestic Dog Wombs for Birth
Once the embryos were ready, Colossal turned to domestic dogs as surrogates for the birthing process. This technique, similar to past interspecies surrogacy successes, allowed the modified wolf embryos to develop to term. The method is common in animal cloning and conservation science, but it underscores that these “dire wolves” were born through the bodies of everyday household pets—not ancient megafauna.
