I get my new APBT puppy on Monday. I have a 4 month old staffie male called Fido. The APBT (Skylar) is a boy as well. I am a little worried if they start fighting. Are there any steps to prevent them from fighting or will it happen anyway. My next door neighbour has got 2 APBT's. A boy and a bitch. They are brother and sister. The boy (Pablo) is about 1 and his sister (Paris) is 4 months old. They are starting to fight as well. I thought I would ask. Thanks in advance for any info.
