The Unbreakoball is a great example. It certainly hasn't broken, because she hates it. Hilariously.
She likes squeaky toys now, though. When she was little, she seemed to think she was hurting them, perhaps because of the way we taught her bite inhibition (the yelp 'n' stop playing approach).
So of course the toys Elka likes best are the cheap made in China kind. The Hartz kind. The kind you get from Walgreens. They're a step up from what I feel like I can rip apart with my hands, anyway.
The JW Pets toys are nice and durable (she has a small Bad Cuz and a big Bad Cuz), but she doesn't play with them much. Maybe they're too hard to squeaky, and that's why she likes them less? I really couldn't say. If she has one, she'll frequently look for the other, and put them together.
But, much like those much lauded family stories of kids playing with the boxes rather than the toys on Christmas morning (and Elka also likes playing with small cardboard boxes, by the by), dogs have their own ideas about a lot of things. Fun is one of them!
