We have 2 pit bull puppies, 2 doors up. That are somewhat nelgected. They are around 4-5 months old a male and female. Female is looking kind of skinny. The boy seems to be picking on her. He is growling and biting her. I hear this every morning around 0730 at feeding time also I see him fighting her over toys. Well yesterday afternoon they were tied to the fence close together and the male was growling and biting the female and she was yelping. I yelled loudly at them and he stopped. By the time I got to their yard the next door neighbor had come out and moved them far enough apart so that he could not get her. The owners were not home so I called the ASPCA, but no one would come when I told them that the neighbor had gotten them apart. I am sure that there will be more instances like this one. I need suggestions on how to separate them when they get older or if they do not stop fighting when I yell. I am sure that this will happen again. This is really very upsetting and the owners seem to be clueless about leaving them water and properly watching them. I am so afraid that something terrible is going to happen.
