Your Dogs Sense of Smell

Your dog’s brain is specialized for identifying scents. The percentage of the dog’s brain that is devoted to analyzing smells is actually 50 times larger than that of a human. It’s been estimated that dogs can identify smells somewhere between 10,000 to 100,000 times better than you can. Dogs rely on scenting to the same extent that you rely on your vision. Humans have about 50% of their brains devoted to vision, the same percentage that dogs have devoted to identifying and cataloging smells.

Today, some scientists are training dogs in the hopes that they may one day be able to reliably diagnose certain forms of cancer by smell. There are specially trained dogs that are used to warn of epileptic seizures, low blood sugar and heart attacks and more. Dogs have long been used to sniff out explosives, truffles, illegal drugs, contraband food, identify where termite nests are hiding in your home, track criminals and find missing children.

This extraordinary sense of smell can work to your disadvantage during the process of house training your puppy dog.
