Dog nose fact – Why do dogs have wet noses?
The moisture on dogs’ noses has two good uses: to help keep the dog cool, and to help the dog smell. Although dogs only sweat through the pads of their feet, they can also shed heat through evaporation from their mouth (panting) and from their nose. The thin, clear moisture produced by a dog’s nose is actually mucus, rather than sweat. The mucus also provides a good surface for dissolving chemicals from the air and absorbing them into the skin, where the cells that detect smell are located. Often, a dog that is actively sniffing and alert will have a wetter nose than one who is relaxed or asleep. Additionally, dogs will lick their nose to sample the chemicals that are stuck there and present them to another olfactory sense organ on the roof of their mouth. Together with the extensive, sensitive folds of tissue within the dog’s long nose (called with nasal turbinae) and an enlarged olfaction area in the brain, these adaptations give dogs the excellent sense of smell for which they are renowned.
Dog Nose Games
Pick the Hand Here’s a simple way to rev up your dog’s nose. First, get some small tasty treats that will fit into your hand. A bit of turkey meat or cheese will work better than kibble because of the former’s stronger aroma. Next, take one into your palm and make a loose, palm-down fist. Then, with your dog sitting in front of you, offer her that fist, and let her sniff. While doing so, say “Find it!” Once she has sniffed it, open your hand and offer the treat, saying, “Good find it!” Repeat this a few times. Then, add your other empty fist. Don’t let her see which hand you place the treat into. Next, move your closed hands back and forth, then offer up both to her, saying “Find it!” When she sniffs at the treat hand, say, “Good find it!” and open your hand to give her the treat. Repeat this, alternating the hand in which you place the treat. As you continue, wait until you can see her nose really “alert” on the treat hand before opening up. The idea is to teach her that the location of treat varies and can be found only by scenting it out. Once she gets it, add a friend’s two fists into the mix, making it doubly hard for her.
