Meet Rocky! He is a Blood Hound puppy. Keely and Tiffany are giving some pointers on touching his feet and ears while he is still a puppy to get him used to having nail trims and ear cleanings.
Bloodhounds are known for their tracking ability and this has everything to do with that marvelous nose!
When a bloodhound sniffs a scent article (a piece of clothing or item touched only by the subject), air rushes through its nasal cavity and chemical v***rs — or odors — lodge in the mucus and bombard the dog’s scent receptors. Chemical signals are then sent to the olfactory bulb, the part of the brain that analyzes smells, and an “odor image” is created. For the dog, this image is far more detailed than a photograph is for a human. Using the odor image as a reference, the bloodhound is able to locate a subject’s trail, which is made up of a chemical cocktail of scents including breath, sweat v***r, and skin rafts. Once the bloodhound identifies the trail, it will not divert its attention despite being assailed by a multitude of other odors. Only when the dog finds the source of the scent or reaches the end of the trail will it relent. So potent is the drive to track, bloodhounds have been known to stick to a trail for more than 130 miles.
A bloodhound’s outward appearance also adds to its tracking ability. Loose, wrinkled skin around the face helps trap scent particles and long, drooping ears that drag on the ground collect odors and sweep them into the nostril area. The dog’s long neck and muscular shoulders, which slope into its strong back, allow it to track close to the ground for miles on end.
Despite the technological advances of our current age, many experts agree that these canines are a greater asset to a police force than some of the best high-tech surveillance equipment. Their extraordinary ability to discern a cold trail has sent them on fruitful missions, following tracks over 300 hours old.
