Today there was a pretty big dog fight between Mia and Nadja. I was playing with Nads and Mia came I and when Nads bent down to pick up the toy Mia grabbed her front leg and the whole situation escalated into a pretty bad fight. My mom and I had to scream for my dad to help break them up because we couldn't. My leg got a little too close to Mia's face whil pulling on the dogs and I got bit not once, not twice, but three times and they definitely broke the skin. Thankfully it's not that deep. The girls have gotten into fights before but never to this degree. Nadja's limping but it's getting better, Mia is totally fine. I just don't know what to do. I'm worried that one day Mia's going to pick a fight when Nads is all grown up and will get seriously injured especially since she's not as young as she once was. How can I prevent these fights from happening. We've kept them separated after the fight splitting the time each has in the kennel. I don't want more dogs or people hurt.
