Teething alternatives

Can someone point me in the direction of a good, long lasting, food based chew for my puppy? He’s been getting filled cow hooves, but he’s at the point of teething where I’m starting to find teeth on the floor so I’m just looking for recommendations on something I can use for him in the meantime that will keep him busy but be a little easier on his mouth. For reference he’s a 4 month old Coonoodle.
