A woman noticed that her pet dog, a cane corso, started peering at her with a strange expression. Its behavior changed, and would frequently look at her oddly as if checking on her when she leaves the home. Thinking that the dog might be sick, she took it to the vet, only for the vet to ask her whether she was pregnant. As it turned out, she was. The dog knew before she did. She joked on social media that it was the most expensive pregnancy test ever, given the cost of an average vet visit nowadays.
