Be Advised:  Neither the product info on this page from Irish Setter nor the Irish Setter website makes ANY mention of this shoe being waterproof.  If you want the waterproof version, looks like you'll need to get the 3874 Soft Paw Waterproof Oxford.

UPDATE: It looks like Amazon has removed the claim that this shoe is waterproof from the product description.
