Why Do Dogs Have Dew-Claws?


dog dew claws are the remains of the first fingers of the ancestors of dogs. When the family dog began to specialize as runners during evolution, his legs became longer and narrowed five toes on all four feet. The first toes disappeared legs wild dogs , but before the legs have survived as relics affecting more soil dog dew claw .
This design gives an impressive turn of speed wolves dew claw injury , on 35 - 40 mph was recorded dog dew claw repeatedly at dew claws removed cost distances up to a quarter mile . The individual limits of five meters were measured.
dog dew claw Resistance is also remarkable dog dew claw distances. Huskies, the closest race of wolf ancestor, dew claw injury have been known to pull a sled over 500 miles in a total time of only 80 hours .
Become the man in dew claw injury the dew claws removed cost management of sacrifices in other directions dog dew claw.
The ability of dogs to climb and dog dew claw jump worsened since their performance has improved. But his greater speed and greater resistance to persecution have become extremely efficient and sufficient for wild dogs to survive in the world successfully for the hot tropics to the frozen ground dog dew claw .
RAM should be well on its way,dew claws removed cost dog dew claw a victim of the coming of age of the dogs track athletes . But if this is the case, then it seems strange that many breeds of domestic dogs seem to reverse the trend. One imagines that modern dogs eliminate further former canine ancestor are wolves or dingoes , have lost all their spurs, "thumbs " dew claw injury front legs following the " toe " of the hind legs forgotten dog dew claw.
However , the reverse is the case . dew claws removed cost Many breeds of modern dogs have all four pins present. The back is not as strong or attached to the front, usually consisting of no more than a free bone and claw foot badly connected by a small flap of skin , but still represent a dog dew claw slight twist in dogs evolution .
 Races with these spurs back foot , dew claw injury dog dew claw but they are residual , are closer in this sense, at least to the ancient canine ancestor the wolf or Dingo . Why turn it into a place taken original state ?
The answer is in the process known as neaten - features infant survival in adult animals . This is what happened to the dogs during the 10,000 dog dew claw years of selection controlled by man. They have , indeed, become wolves minors. They can reproduce , but keep most of their models for young people, such as joy and obedience to a pseudo- father - the human owner . It also maintains a number of anatomical characteristics of children, such as floppy ears seen so many races today .
Rams hiring more part of this process. We have generated a series of increasingly extreme in the different characteristics of modern breeds , but in other ways that are more primitive than the highly specialized wolf all were fired. In other words , when we started to turn the wolf into the dog we turned back and forward dog dew claw.
Interestingly, dog breeders feel intuitively that dew claw injury there is something wrong with spurs and advise that must be removed when puppies are between three to six days .
dog dew claw They recognize as " trend unspecializing " and correct . The excuse that if these rudimentary claws are allowed to remain , may be taken in the dew claw injury undergrowth and torn is given . Considering that dew claw injury are inside of the legs and on earth , it's pretty unlikely accident and banal excuse, but the unconscious desire of the Specify " dog paws is strong enough to ignore . (Except in specific races, such as the Braid dog and Great Pyrenees , where the spurs of the hind legs should be kept to meet the standards of the breed dog dew claw. )
