Why Your Dog Growls At Some People And Not Others

People smell.

People have different scents to dogs. Dogs are much better at smelling than humans, in fact they are 10,000-100,000 times better.¹ Because of this disparity, we cannot imagine all the information that our dogs can gain from someone’s scent. Amazingly, trained scent dogs can even distinguish between the scents of identical twins from the same environment and eating the same diet. A dog can smell where you have been and who you have been with, maybe for a long time.
