yes she is pregnant, my concern is if this agression will subside

I sincerely thank all of you who have replied to my delima. I would like to respond individually but one of my emails was inadvertenly deleted so i shall explain myself as you all seem I should do,
I got a beautiful tricolored Basenji male when he was 9 months old and was not given the attention he needed to socialize, we did have a "transitional phase" I was very aware that their temperment is not like other dogs. I was convenced that he needed a companion, My niece in PA did her best time and effort to get me a compatable female. I did ask the breeder to research the bloodline and was satisfied. Her only reward was to give her a pup so I decided to breed if only for one litter, I have not decided yet. I am a very responsible person although I admit I am not knowlegable about the breed. I came to this forum because the Basenji is a breed all its own that only lovers of this breed would be able to express their complete understanding of. That is what I am asking of this forum. Your help will be greatly appreciated,
My Sincere Thanks, Lorraine Munger

My pregnant femal basenji viciously attacked my older female boston terrier, they never did have great love for on another, but also had no confrontations. She was relentless and i could not break her off, it stopped when she was to tired to continue, my boston was seriously injured, is this type of agression instinctive to a female basenji while pregnant. will she become more agressive with pups, will she attack her male mate that she is constantly with if he is in the same area or does she need complete isolation from others after having the pups, forlorded, lorraine

i am joining because there are no basenji psychologist that i know of, but a pool of experience would also help me with my pregnant female
