Chewers- is this okay for toys?

when we got out jack russel it was 8 months and chewed about everything, i wouldn't recommend plush toys as they end up eating the contents and making a huge mess, treat releasing toys are always good, we have 2 but one of them he gets a bit too hyper with, decent rope toys are great too as they're harder to chew up and can last a bit longer than most!
