There seems to be a lot of different opinions on puppy toys out there lately. I'd like to hear what folks here think on the following options, thanks! How many 'types' of toys. Just Kongs? All safe toys? How about plush? How many at a time? Leave just one or two for the puppy to learn not everythign on floor is his? Rotate the types of toys to keep him interested? Leave tons of toys out already for him to go through and always have something he's interested in available? Does NILFI allow for leaving his favorite toy out all the time? Should toys always be picked up to enforce NILIF? If yes, how long should he be allowed his toy? 1 hour, 8 hours? Thanks for everyone's input. Need to re-evaluate what's best now that the puppy is almost done teething .
