Sounds like the heat had a lot to do with this
and I have heard a lot about female dogs not getting along
If it was me I'd get them fixed but I'd also make sure they stop whatever they are doing when I call
I have two boys and they get into scraps sometimes that I have to stop
It's like the drop command but I have them just stop whatever they are doing
I've reinforced it with a pointed finger
and it seems to be working very well
