Toy suggestions needed

I have a 4yo male springer spaniel who needs a lot of physical and mental stimulation. He's energetic and quite intelligent.

I've found he needs interactive things to do at home, especially in the winter when his walks are a bit shorter and less frequent.

The problem I have is he is a really aggressive chewer. He's destroyed almost every toy he's had, despite trying to choose toys carefully and supervise play as much as possible.

So toys that are stimulating don't last, and toys that are tough enough to withstand his teeth tend to be basic and thus bore him quickly.

I've seen the 'chase buddy' advertised, but loath to spend money on it in case he wrecks it in 5 minutes. Does anyone have any experience with the chase buddy to say how durable it is? Any other recommendations for toys that are both interactive and durable?

Thanks!
