We’d like to take our two dogs on holiday to France this summer (probably the last time it’ll be easy to take them abroad ...)

Ideally, within walking distance of a beach (dh wants surf, I want to be able to swim), dog-friendly, bit of culture and things for older teenagers (if they deign to accompany us ). Not too hideously long a drive, but reasonably guaranteed decent weather. We’ve been to Lacanau-Ocean a few times but would like somewhere new. Any recommendations?
