Last year was his first year of real hunting. He did very good for being a new pup. He retrieved he followed scent trails etc. very good the first year. He actually loved to retrieve birds, or dummies, or tennis balls last year. But now this year, he has a soft mouth. I dont know how that came about, and how do i fix it? Or is it possible to fix? Like I said, last year he loved to retrieve and do all that, and now this year he'll barely pick the ball up when you throw it, he'll barely pick up the dummy when you throw it. Any suggestions will be welcomed!

Thanks!
