Beau is the sweetest thing on his own. He is mostly acclimated to women (he has 2 mommies), but gets along with men and older children. My wife has had him for 10 years! But he has been showing male dominance aggression toward our 4 year old dog for 4 years. He also used to be good with other dogs in the dog park when he was younger, but once he turned 5, it was like no other male dog was allowed around. Our 2 dogs have had 6 bad fights in the last 4 years. He is not doing well with our toddler now either. As a baby, he was fine with our son. But now that our son is running around chasing them and a little rough with his 'pat-pats'. The dogs are growling and snapping at him.
