I'd use some of his food and create the drive. IF this is a puppy from the ame litter, if I recall they are still very young. If not, sorry about that.Anyone have suggestions for a pup that doesn't seem to be food motivated? Hard to train if he losing interest quickly... any suggestions? I do use a clicker.
I specifically PICK puppies with food drive. It's a criteria for me when I get puppies. As well as toy drive. If you search for a thread on working ethic, Doberkim posted a fantastic response on how to increase/rbuild food drive.
