Yes they can. The coat will act as protection against the heat as well a against the cold. Depending on what your doing with your dog, pet or show will probably depend on the cut you give it. If you just have the Bouv for a pet and your in a hot climate you might prefer the utility cut which is much shorter. If your going to show your Bouv then his grooming will have to be longer and more work will be required so he is comfortable. Make sure you keep him mat free and plucked so that his coat will be healthy and will help keep him cool.
