Ears

I too believe in the moderate long ear makes a better hunting dog with more bottom and better nose which is the type of dog I like…
Sometimes when we breed for a certain trait, we get other traits along with the trait we are breeding for without realizing it is happening…
Example…Again personal theory…we are breeding racing greyhounds and we want to breed the absolute fastest so we can win wherever we go especially when entering the bigger races…it is somewhat easy breeding this trait on account our dogs are fast and win their fair share…we know the fastest times out there so we have our goals set accordingly…as we consistently breed faster dogs something else is happening…the heads are getting smaller and the nose more aerodynamic and that makes logical sense…the lighter and smaller head increases speed, is more aerodynamic and so is the nose…something else we did not see…the skin got thinner…so why is this happening? There are two possibilities that make sense…one is that the dog is lighter in weight with the thinner skin making him faster…the thinner skin is also allowing him to run cooler as he speeds around the track using a tremendous amount of energy while creating lots of internal heat…but with the thinner coat it is much easier to give off more heat allowing the dog to run cooler…some of those hidden traits are genetically associated with a faster dog and other hidden traits are due to other reasons like already mentioned…lighter weight and aerodynamics…the little things that give the winning edge…
The longer ear…tends to be on a slower dog that keeps his nose down in the track when trailing…
The medium ear dog tends to trail with his head up…sometimes tracking off wind currents and looking to see or hear the game ahead so the dog can leave the track…the good ones use the wind currents to find the hot end of the tracks…I wrote enough about the greyhound whom I know very little about…the same type of examples apply to the long eared dogs….and as different traits apply to medium length ears…
There are exceptions to every rule, but I tend to look at the averages for better accuracy on personal theory…
