They have never once so much as growled at each other and today the big one(Lab/Weim) runs up to the Corgi and they start going at it. The little one- a girl is scared and is hiding under the desk. I guess its food related but im not sure. They actually share the same bowl and have always done so. They dont have feeding times either, i just feel it up when its empty. Im worried because this so all the sudden like maybe one is sick. They stay together in my room everyday while im a work which has me worried now. The Lab/weim has never insticated anything, ever, until today.
