Just How much Nose (Olfactory Size) is Required to Trail a Coon ???
We know that a German Shepherd is on the fringe of Having Enough Olfactory to Trail a Very Hot Coon Trail.
German Shepherd Crossed to Hounds Were Very Good in the Early Field Trials and So were Hound X Greyhound Crosses..
What if thru the introduction of other Dogs eather by Accident or on purpose have Reduced the Size of the Olfactory to the Point that some Hounds can only Trail a Feeding Coon Track but Can't Handle a Coon on the Run Track and Just Falls Treed at that Point ??
The Hounds Get their Olfactory Size from the Bloodhound but
Then thru Breeding to Obtain the Different Breeds of Hounds and Bird Dog the Size of the Olfactory was Reduced ..
To Develope the English Fox Hound, Fox Terrier , Grayhound and Several other Non Hounds were Used on the Base Line of St. Huberts hound (Bloodhound) and the Talbet Hound (The White Base Color Hound) Thus Reducing the Size of the Org. Olfactory System ..
Number of dog olfactory receptor cells = 1 billion
Number of bloodhound olfactory receptor cells = 4 billion (Shier, D., Butler, J. and Lewis, R. Hole's Human Anatomy & Physiology, Boston: McGraw Hill, 2004)
Surface area of olfactory epithelium (contains olfactory receptor cells) in humans = 10 cm2 (Bear, M.F., Connors, B.W. and Pradiso, M.A., Neuroscience: Exploring the Brain, 2nd edition, Baltimore: Lippincott Williams and Wilkins, 2001, p. 269)
Surface area of bloodhound olfactory epithelium = 59 in2 (Shier, D., Butler, J. and Lewis, R. Hole's Human Anatomy & Physiology, Boston: McGraw Hill, 2004)
Area of olfactory epithelium in some dogs = 170 cm2 (Bear, M.F., Connors, B.W. and Pradiso, M.A., Neuroscience: Exploring the Brain, 2nd edition, Baltimore: Lippincott Williams and Wilkins, 2001, p. 269)
Area of olfactory epithelium in cats = 21 cm2 (Bradshaw, J., Behavioral biology, in The Waltham Book of Dog and Cat Behaviour, ed. C. Thorne, Oxford: Pergamon Press, 1992)
