i had a german line male(WATZER) with a long gorgeous tail who chased his tail like he was stalking a snake and would then attack it....we tried everything.....he didnt start this until he was about 18 months and never did as a younger dog...he was a high drive male and was NEVER bored....he was the kind to chew tires and would carry truck tires around his neck....in the beginning, he did not chew it but evidentually started and it got down to the bone and when he wagged it, blood over the house walls...we tried covering it and used eliz collars at the end and nothing helped....we finally had to amputate the tail leaving a stub like a dobe...we thought that would stop it but he still would stalk it but couldnt grab it and developed a new habit of going round in circles as he was now really frustrated that he couldnt catch it....i was worried he'd rupture his spleen but never did and he lived to an old age of 13 years and died of bloat...he will always have a special place in my heart Natalie CLOVERLEIFE HILL KENNELS Jerry and Natalie Stewart http://www.cloverleife.com/ CH Cloverleife's Dimples, CH Cloverleife's Cappuccino CH Carmil's Amadeus v Windywood Website Updated 2004 Show and Pet Puppies available ============================================================================ POST is Copyrighted 2005.
