Dog Friendly Beaches during the Summer

Hi

We've just spent a couple of weeks in the New Forest Centenary Site.  Most of the beaches along that coast have dog friendly sections (even Bournemouth has a couple of sections) which is great because our little dog absolutely loves the sea.   He won't swim but loves a paddle racing up and down the sand with his tennis ball. 

We'd like to go somewhere different next year (having been to the New Forest for the last couple of years) and wondered if anyone had any suggestions of other areas to visit, including club or cl sites please? 

We live in the Derbyshire area so quite central and happy to go North or South.

We do visit Bridlington in October when the beaches are open.

Thanks very much
