The fights are getting more frequent and more aggressive they will just attack each other out of no where. Can u explain why

The younger dog is coming into maturity and may be trying to become the one in charge. The best place to start is have them each fixed to minimize the hormones to help withbthr fighting. From there it will be watching them and keeping them separate until they grow up a little note and see if this is a phase
