2. You are correct about the genders, and it's at least 30 if I can remember correctly and as far as I know really only your female needs it. But it doesn't hurt to check if the male has charisma as well.
3. Yeah, in a way. Pups can inherit boosts / defects from their parents and grandparents (sometimes not the same one)! Most of the time they have a mix of colors between their parents. But sometimes it can be random with the boosts and defects.
4. Maxed battle and agility are the main things to help train a battle wolf. But it depends on what you want your wolves to do in explore to max any other attributes. (I'm not much of an explorer so I don't remember what they all do on the top of my head) Boost wise, Divine Health is probably the most used for battle wolves! Elite Speed and Crushing/Inner Strength are good too. Of course you can train a wolf with any other boost / defect. Edit: Heavyweight wolves are also better! (130+)
