Searched Everywhere for An Resolution: Custom AI Question...

This was more of a test since I've never explored this before.
So I keep getting this error when adding a custom AI...

Code: 
Errors:
+ Content/Internal/MobileEngines/BaseCreature.cs:
    CS1502: Line 2526: The best overloaded method match for 'Server.Mobiles.SecurityK9AI.SecurityK9AI(Server.Mobiles.SecurityK9)' has some invalid arguments
    CS1503: Line 2526: Argument 1: cannot convert from 'Server.Mobiles.BaseCreature' to 'Server.Mobiles.SecurityK9'

I've researched and all I found was the implementation of it all:

BaseCreature.cs:

Code: 
...
                case AIType.AI_FlyingPredator:
                    //m_AI = new FlyingPredatorAI(this);
                    m_AI = new FlyingMeleeAI(this);
                    break;
                case AIType.AI_FlyingThief:
                    m_AI = new FlyingThiefAI(this);
                    break;
                case AIType.AI_Omni:
                    m_AI = new OmniAI(this);
                    break;           
                case AIType.AI_SecurityK9:
                    m_AI = new SecurityK9AI(this);
                    break;
          }
}

BaseAI.cs:

Code: 
...
public enum AIType
    { 
        AI_Use_Default,
        AI_Melee,
        AI_Animal,
        AI_Archer,
        AI_Healer,
        AI_Vendor,
        AI_Mage,
        AI_Berserk,
        AI_Predator,
        AI_Thief,
        AI_SecurityK9
}
...

This was modeled after the drug sniffing dog someone came up with to go along with my Harvesting system, I just wanted to separate things and make its AI a script of it's own and put it with the rest of the AIType scripts. This is the custom AI script:

Code: 
using System;

                                        }
                                    }

                    mark = null;
                }
            }
        }

        #endregion

        //protected override BaseAI ForcedAI { get { return new SecurityK9AI(this); } }

        public SecurityK9(Serial serial)
            : base(serial)
        {
        }

        public override void Serialize(GenericWriter writer)
        {
            base.Serialize(writer);
            writer.Write((int)0);
        }

        public override void Deserialize(GenericReader reader)
        {
            base.Deserialize(reader);
            int version = reader.ReadInt();
        }
    }
}

Now I know that the ForcedAI will override this issue, but I was wondering if there's a way to seamlessly intertwine the custom AI into the server like AI_Melee, AI_Animal... etc. Is there a core edit I am missing?

Any help would be appreciated. Thanks :)

Thank you Ravenwolfe!

You helped me fix the issue. All I had to do was change the way this line in the SecurityK9AI script read:

From:
Code: 
public SecurityK9AI(SecurityK9 m) : base(m) {}

To This Change:
Code: 
public SecurityK9AI(BaseCreature m) : base(m) {}
