We have a 5month old GSP, who we just brought home from the Breeders on December 15th.  He is a great pup so far.  We are wanting him more for a family dog than hunting or show.  What kind of training should I look into for him?  Is he getting too late of a start?  We have him Crate trained for bedtime and when we are not home.  I have tried walking him with the leash on and he does not seem interrested in that?  But I also would like for him to be able to walk freely by our side...any suggestions would be helpful.  Also any suggestions on dog food??Thanks
