There are a couple of reasons why this was done a few decades ago.  Dogs with curved tails are known to be chasing flies and fleas that got on their tails. Owners of the dogs found this a nuisance that all of a sudden a dog would keep chasing its tail for several hours in a week. Due to this dogs forgot their "job" which was to guard sheep, or pull carts, etc.\nSecondly, certain dogs go very wild if we pull their tails, even if its done playfully. They simply get mad at you, bite you or even kill you, if you are small.  Since little children always found it playful to pull the tails of the dogs and this meant a potential danger to their lives, the owners cut their tails short. \nEver thought of the word CUR-TAIL? :-)
