What are the characteristics and care requirements of dogs with a double coat?

Dogs with a double coat have two layers of fur: a dense undercoat and a longer topcoat. These dogs shed more and require regular grooming to prevent matting and keep their coat healthy. They may need extra care during shedding seasons to manage their fur. Regular brushing, bathing, and occasional trimming are important for maintaining their coat. Additionally, double-coated dogs may be more prone to overheating in hot weather, so it's important to provide them with shade and access to water.
