Places to visit in devon/somerset & dorset

Hi
going down to the south on holiday next year will be staying in the areas of devon, somerset & devon, any one know of any dog friendly places to go and visit?

Thanks

wareham forest in dorset, lulworth cove and walk to durdle door along the coast,

both of these are in dorset though and i regularly visit the area

Somerset; Stock Hill Forest on the Mendips is huge and long hardcore paths. Westhay Nature Reserve at Westhay, Combe Hill Woods just outside Street.
All are safe places to have off lead walkies.
Oh and the Tarr Steps on Exmoor, hour long walk up and down the river, absolutely beautiful.
