I have a 16 month old great dane male. He has been my best friend since he was 8 weeks but all of a sudden he is getting aggressive with all males. He has akc paperwork and is a merlequin. Very large and loves to lay on the couch all day. He loves my daughters and myself with everything he has. But is acting risky around my son and boyfriend.
