Hi there!
We have a 8month old cross bull terrier, stafiie,male.we bought 2 6week old females same breed! Tyson is fine and playfull with them. But would we pick up some problems later as the females grow bigger? We are planning on spading all of them would this prevent any aggression for the females part?

Regards Scharne

Unless you have heard otherwise, don't assume aggression eventually. They will all be neutered to take out that tendency, that can happen with any breed in same situation.
