A dogs nose...

A dog's nose is a very sensitive thing you know!

For example, did you know that:

  1. Usually, the longer the nose, the better the sniffer.
  2. A dog’s nose also has lots of mucous inside. If unfolded and spread out, the surface area of the dog’s nasal membranes would be about the size of a handkerchief! It's this mucous that allows the dog to have such an elevated sense of smell.
  3. A dog's sense of smell is 1-10,00 times greater than ours!
  4. Dogs have been known to detect cancer with their nose. According to the national Geographic website, this is because breast-cancer and lung-cancer patients are known to exhale patterns of biochemical markers in their breath. The different metabolic rate of cancer cells helps a dog sniff them out. See the Youtube link below for more information.
  5. A discharge from the nose generally means trouble. Several diseases involve nasal discharge, including distemper, bacterial rhinitis, infected sinuses, and kennel cough (in puppies and toy breeds), so a trip to the veterinary clinic is definitely in order if the nose begins to run.
