Male pups **generally** mature more slowly than females - the first few males I had were rock stars from day 1 - Ghost, Wolf, Cito and Danger and now apparently little Koug as well....but most of the pups I know of from todays popular WGR lines mature more slowly than their female peers....
I have done pups from 9 weeks and trained them, and had others I let go to over a year before working....one of my girls lives with friends, as a pet, constantly has a cuz or toy in her mouth, and when I finally got to start working her was super drivy....nothing was done to "build" drive - it was there....a couple of very very highlevel experienced trainers/helpers have critiqued her as a rock star LOL LOL without any knowledge of her 100% full time job as a pet who does not even live with me.
BUT - you can condition or "build" drive....you can also do what I call deprivation training to get more drive from the dog......
Many many many lower drive dogs are titled through diligence and conditioning rather than natural genetic talent.....if you want to train and title for fun, and understand that your first dog is a "learning experience", then do what YOU feel right for you and your dog.....I had trainers who believed dogs should live in kennels etc....I feel bad when I remember putting my dog in a kennel outside with an igloo overnight in the winter due to the trainer's INSISTENCE that he not be allowed in the house....that did not last!!!! The dog still trained and had drive and did very well (except for a few training caused long term ob issues!) and got Sch3 for me with super protection scores at every trial!
Compulsion has it's place in controlling a dog in drive. Some dogs who are genetically very "biddable" can do well without it - IMO need for compulsion is as much based on the genetics of the dog as the training philosophy. Csabre was taught dumbbells totally without compulsion - a well known German trainer held her up as a shining example of the success of a force retrieve at a seminar.....LOL....he went on and on that THIS was the best retrieve he had seen there....and THIS was what you got with a FA - I just told him quietly that this was "not FA".... several times - it was kind of funny when I told him -very quietly !!! - I did the retrieves with a clicker.....he threw his hands up in the air and walked away from the whole group...and her daughter will do retrieves just as nicely with barely any training except the front and out....so in my mind, obedience training success is as much genetics of the dog as philosophy.
