I'm not that familiar with Point Reyes, but Carmel is VERY dog friendly. Many stores will let you bring your dogs inside, especially the dog boutiques. And there are a couple restaurants that have outdoor seating for people with dogs and a dog menu. Forge in the Forest is a great restaurant that we used to take our dog to. I've never stayed at a hotel there but I'm pretty sure there would be dog-friendly hotels. Nearby Pacific Grove has some nice walking paths along the beach that you can bring your dog to, like Asilomar beach.
