Vast beach with plenty of quality running space for ball chucking!
So many people have recommended Talacre Beach to me over the last couple of years as perfect for dogs, and having now finally been myself, I would happily recommend it to anybody. It is easily one of the best dog-friendly beaches I've been to as for starters there are no limitations on use by dogs in the summer.
Talacre is a vast open beach and even at it's busiest you'll still feel like you have the place to yourself for much of the time. If you have a dog that loves to run, you'll easily have plenty of space for ball-chuckers without impinging on other beach users. The sand is lovely to walk on with bare feet and is clean and litter free. Water is still cold though, ;)
There are plenty of amenities conducive to a great day out on the approach road to the beach including a great pub: 'The Point' which allow dogs inside and a cafe which sells the Cheshire Ice Cream Farm ice-cream. Yummy...
If only it was a bit closer than an hour and 20 minutes away, I'd be there all the time!
