Do Kerries fight with other dogs?
Kerry Blues display inter-male aggression. Like many terrier breeds, early Kerries were quite prone to fighting and aggressive behaviour. Careful breeding has greatly improved the Kerry disposition. A Kerry can be trained to mind his own business, but he will not back down from another dog if he is attacked. Early training and firm, consistent handling will prevent problems in most situations, but it is best to have only one intact male Kerry in the household. Some Kerry experts advise having only one male in the household, period, regardless of whether or not he is neutered.
