Dogs sniff so much, because they want to identify whatever they are smelling. It could be an object, a human or anything else. It doesn´t matter much to them what they´re sniffing, they just want to label it as either dangerous or safe.
Whenever pooches meet another dog or a human, they sniff in order to find if what they are smelling is not a threat to them.
You´ll surely see your pet sniff when you take him to the park, or to the backyard. Please always walk your pooch on a leash and be thankful for having a dog in your life.
