Glad to hear everyone is alright.

Everytime to have multiple dogs together, whether they live together or at a dog park, at some point, this is bound to happen. LIke little kids, they don't feel well, or have had enough and get into a fight. It is horrible to watch sometimes, but the bottom line isn't that it did happen...it is trying to learn what may tigger it and do your best to avoid those situations. It sounds like you have a few ideas and are trying to work on it.

It is possible that as Kiara gets a little older, Nala may feel they need to establish herself as the top female. Once they figure it, I'm sure they will get along fine.
