I'm glad to hear everyone is ok, and clean now!!

My dogs have had a few fights, and every time it has been over a bone or some other type of food--never while they're actually eating, but maybe a treat or something. Kito and Abbey had a fight over a bone, Kito and Jada got into it one day over a toy that had treats in it, and Abbey and Jada had a fight or 2 over a bone.
Honestly, they are all big sweeties. Give Kito a greenie though, and let one of the other dogs come near him, and he turns into the devil.

That's how I've solved the problem though--no one gets bones, treats, greenies or whatever, unless they are separated, or supervised. We haven't had a fight in a long time.

I think I understand how Nala feels, because Abbey was the same way for a while. Kito was the "cool" dog, and Riley was a puppy--no one (meaning people who came over, not us) paid any attention to our little lovebird. It was like she had sibling rivalry for a while. Plus all of the attention Riley got because he was being potty trained and stuff--she just felt a little left out, I think.

Again, I'm glad everything is ok
