We saw a beach in Italy last week for dogs. It was called Bau Bau Beach. This was one of the greatest ideas I’d seen. There were dog bowls and dog showers everywhere, a roped off part of the beach for the dogs to play in the water, and instead of chairs and umbrellas to rent, you could rent a tiny yard with a white picket fence for your dog to play (also with chairs and umbrellas for humans).
At one point, the idea was brought up for a beach for cats, but we quickly dismissed that as it would just be a giant litter box and cats hate water.
