What a handsome boy.
Showing does take a toll on you and money also.I have a family friend who shows his Afghan.Cash is one point away from champion.I also have a friend who has a champion Dobe.His sire was world champion in 91 and Dam was Can/European Champion.
If you don't mind me asking,what are the parents backround?When you were looking for a pup,did you have the intensions of showing?The reason I ask is your breeder will know wich pup is show quality or pet quality.
I agree with doing the SchH.My GSD is titled in SchH III.He is also a retired Police Dog.He had to complete and pass Obedience.Then went through the 3 stages of SchH.SchH I starts at 18 months,SchH II at 19 months and the final SchH III at 20 months.Trust me,you don't need to train your dog for this.He will protect you.
Also,have you talked to your breeder about this?
