Why does my dog sniff other dog’s behinds?

A dog’s nose is about 10,000 – 100,000 times more sensitive than a human’s nose. Sniffing rear ends and other private parts is a form of chemical communication between dogs. This common behavior is how dogs learn about another dog’s diet, gender, where they have been and their emotional or sexual state. It’s similar to reading a diary that was written with scent molecules and pheromones.

According to Dr. George Preti from Monell Chemical Sense Center, dogs have anal sacs that contain the apocrine gland, which gives dogs that wonderful dog smell, and the sebaceous gland, which secretes the smell of any acids that are inside. These acids are influenced by the dog’s diet, health and emotional state.

Dogs do not get distracted by the “poop” smell because of an organ called the Jacobson’s Organ. The American Chemical Society states that it is a second olfactory organ in the dog’s nose, which often leads directly to the brain and only picks up the smell from this chemical communication.

Why does my dog like to roll in the grass?

Dogs roll around in the grass to mark their territory, in addition to using it as yet another form of communication. Unless your dog is rolling around in something gross, it is better for your dog’s well-being to let them continue. Because we do not fully understand all aspects of their communication, we do not want to hinder their expressions, as it might affect how your dog experiences and learns about the world around them.
Some dogs also roll around in the grass to relieve an itch or a skin irritant. It is important to continuously examine your dog and schedule regular vet visits to make sure your dog is healthy.
