You probably know we train dogs to sniff out drugs and explosives, and I bet that many of you know some dogs can even smell cancer.
Here’s one you probably didn’t know: We use scent dogs to determine when cows are in heat! Not wasting time guessing when she’s ready can save a lot of money when it comes time to artificially inseminate a cow. A bull could tell when the cow is fertile, but his main contribution is usually delivered to the scene, frozen.
Instead, scent dogs have been trained to identify the best time for a cow to get pregnant — even though the dog couldn’t care less!
