New Dog / all female pack problems

Question
Hi Kristin
Our 14 yr old female Shep-Chow passed away 2 months ago. I have a 7 yr old son and 8 yr old female Lab-Shep. We all want another dog.  A couple rescue sites turned me down on adopting a young (4 to 8 mo)female stating the dogs would fight later on in years. I've had two pairs of females in my life and no problems. I feel aggression including fighting is due to poor socialization, boundries and training. Am I wrong? Does it depend on the breed? On the ages? Must I get a male puppy for peace of the pack?  I prefer females.
Thank You
D

Answer
I know someone that has three females-so the sex doesn't matter,it's more important that the two dogs meet and if they get along regardless of sex I feel it would be ok

If dogs are dog aggressive unless the dog isn't fixed(and it's usually males anyways)it won't matter

I know someone that has three females of different ages and they get along great,so if you want a female and likes your dog I don't think they will be any serious issues
