what is the purpose of removing dew claws
Dewclaw There is some debate as to whether dewclaws should be surgically removed.[7][8] The argument for removal states that dewclaws are a weak digit, barely attached to the leg, and thus they can rip partway off or easily catch on something and break, which can be painful and prone to infection. Dewclaw removal is most easily performed when the dog is young, around 2â€“5 days of age. It can also be performed on older dogs if necessary though the surgery may be more difficult then. The surgery is fairly straightforward and may be done with local anesthetics if the digit is not well connected to the leg. Many dogs can't resist licking the surgery site in the weeks following the procedure, so an Elizabethan collar or bitterant may be used to curtail this behavior, thus preventing infection.
Contour plowing Contour plowing or contour farming or Contour ploughing is the farming practice of plowing and or planting across a slope following its elevation contour lines. These contour lines create a water break which reduces the formation of rills and gullies during times of heavy water run-off; which is a major cause of soil erosion. The water break also allows more time for the water to settle into the soil.[1] In contour plowing, the ruts made by the plow run perpendicular rather than parallel to the slopes, generally resulting in furrows that curve around the land and are level. This method is also known for preventing tillage erosion.[2] Tillage erosion is the soil movement and erosion by tilling a given plot of land.[3] A similar practice is contour bunding where stones are placed around the contours of slopes.Contour ploughing helps to reduce soil erosion.
