[Help] My dogs are fighting each other now and I got bit on top of that.

I have an 8 year old that we have had since a puppy, then we got a puppy about a year ago. They played great for a year, then one time they fought over a ball and we had to break them up. Then they seem to play well after that for a month. Well just now they had another fight but worse the younger one started to bite the older one and as I was breaking it up the older dog tried to bite the puppy back and she bit me pretty good on accident. I'm just torn, I'm guessing once they started fighting it will be easier to fight and happen more often?There was a similar ball semi-close to where they were fighting (but it was up high on a counter) but I'm guessing that could be it, I should have gotten rid of all balls between them that was dumb on my part. I'm not sure what to do, I'm attached to the puppy but I think he might be the one that starts the actual biting, my older one just sounds aggressive. I don't want to give up the younger one because me and the wife are pretty attached. Just sucks and pretty worked up over it.Edit: Then what if it was only one of us that had to breakup the fight that would suck, we're also trying to have kids, definitely don't want an aggressive dog around the kid but hopefully it's just a dog on dog issue. via /r/dogs http://ift.tt/2snlcmS
