Purkha lai ta k gaali garne ...parampara ta ramro basale tara we interpreted it only as a part of religious formality and did not think about the good potential it possesed for the benifit of animals. Atleast chetana ko bikash le hami ma janawar lai garne bebahar ma pariwartan awasya lyaunecha, so for the time being let this practice go on. Happy Dog's day:)
