Observations About Canine Sense of SmellA dog's sense of smell is put to use every time a dog comes in contact with man. It tells the dog if it knows the man or other dog and if it's trustworthy. It's extraordinary sense of smell allows it to: - follow the trail of a wild animal;
- looking for mushrooms underground;
- trace a criminal, find a lost child or the best hidden drugs;
- find a person buried under up to seven meters under snow or debris.

Dogs Smell The World: The dogs' most important sense is that of smell. Dogs' nasal cavity is 30 times larger than mans' and it's capacity is even greater yet. Here are some examples: - a dog can smell our mood, and if we accept or reject it;
- when following a trail it can recognize how long it's been there and which way it's going;
- it smells dogs that have been there before on corners, light posts or trees and receives information about it;
- obviously, the dog knows the precise smell of it's owner. It's not good to constantly change perfumes as it may cause confusion.
When a dog is new in a house, regardless if it's a puppy or not, it's owner shouldn't change perfumes for at least half a year. Only this way will the dog recognize your smell.
