My name is Dash!

We have had Dash since he was 8 weeks. He is very loved. He is almost 6 years and in the last six months he has become increasingly aggressive towards our female. He is very territorial and growls and snaps at her. He becomes aggressive with us if we try to correct him. We are heartbroken to re-home him but with small children who visit often we are concerned. He will be best with no children and no other pets. He loves to fetch a ball or frisbee he will sit, stay (sort of) lie down, shake and loves affection. Loud noises seem to stress him out like whistles from a game on tv or gunfire on a tv show. He likes a soft bed in a den or kennel some small space he can get into to feel better. He enjoys car rides. He is a little wary of men but typically adjusts if you let him get comfortable. We want a loving home for him and feel helpless at this point having tried medication and behavior therapy.
