Some dogs can tolerate living outside in a doghouse all year. This depends on the breed of dog, and you want to make sure that they’ve had time to get acclimatized to the temperature,” Dr. Cutler said. “In the cold, having clean, dry bedding can help to keep your dog warm. Having plenty of ventilation and shade in warm weather is important as well. Pay close attention to your dog to ensure they are acclimatizing well if there are really quick swings in temperature.
