just now, in my life time, i've able to keep two females together. and they're both terrier breeds. go figure. i think it's because i'm alpha dog and they all slipped into their niches.
beagles bite a lot also. i had a veterinarian friend who was bitten five times by beagles.
my dog, tippy, who was the soul of love and kindness, didn't like children and i had to watch him like a hawk when we were on the reservations.....the indian children loved him and i always had to talk to him before i let them pet him. my dog, Henrietta, half chow and half german shepherd, lived for someone to threaten me. "make my day" was her mantra.
having it all blamed on one breed isn't right. it's a lot of breeds. and a lot of the way they are treated........thanks, joe.......pat
