Dogs sniff people — even in awkward spots — because that’s how they learn about us. Their noses are incredibly powerful, able to pick up hormones, stress, and even signs of illness.
Most of the time it’s harmless. If it gets awkward or constant, use simple commands, rewards, and play to redirect them. And if the sniffing turns obsessive or anxious, check with a vet or trainer. A little patience and training can teach better manners while honoring your dog’s instincts.
