We have been thinking about a puppy and have a 6ish yr old female. I've heard that a male would be he better choice in a puppy, however never from any reliable sources. It makes sense to me, especially since jasper is a fairly dominant dog with her buddies, but i have only seen her with one male before and she doesn't like him one bit. that is probably because he is not yet neutered though and is constantly pestering her. (she's fixed) jasper has been in a couple fights, (short lasted of course) with libby, who was a foster dog from the spca, but she had her own issues and started it with jasper, never the other way around. she was also not spayed for half the time we had her so i suppose that could have played a part? and also with a 1 yr old unspayed female, once, because sadie was jealous that her owner was playing with jasper, sadie is also a very dominant dog. does this mean we should avoid getting another female? wether our puppy was male or female it would be fixed asap, and jasper has only ever had problems with intact dogs.....
