Squeaky tennis balls which keep their squeak?

[basildonbond]

Dpup's favourite toy in the world is squeaky tennis balls - only problem is he can de-squeak them in about 5 mins flat

Part of me is quite relieved but he looks so disappointed when he can't get it to make any noise

Any recommendations for durable, long-squeaking tennis balls please? He's had the kong air squeak ones which are jolly expensive but don't last long ...

Robert dyas has a great plastic squeaky ball that has never broken. Also costs about £1. The only problem is every other dog in the park wants to play with it too!

I can't find it on their website, but cmotdog has a toy from Pets at Home where you put a 500ml plastic bottle inside with the supplied squeaker screwed onto the top. This bottle lion thing is going strong (with new bottles) after months of intensive love, when everything else becomes squeakless very quickly
