This Must Be Rocket Science!

We know dogs love to play with toys! Especially, they like soft toys and toys that make noise. Just sort of wondering why in the 21st Century, the peepers (noise makers) only last about 90 - 120 seconds average. Why is that?

(And, yes, we know teddy bear type toys do fall apart but we carefully sew them back together, because they are lifelines to many canines!)
