my puppies have got to the age when one's voice changes

my puppies are not puppies anymore, they suddenly are small men with hormones.. the guarding one's territory has become An issue lately, before they used to be really kind to each other, now suddenly there seems not to be enough place for two 3kg:s Men in our household.. and there are awful fights going on about the moose( see the pic) even if I bought them each an squirrel which makes a sound when you bite the tail?(and no: I never tested how it would be to bite the Squirrel s Tail:)) xoxo xoxoanjelina
