Heated blankets can offer several advantages for dogs, particularly those that are elderly, sick, or have short hair. The soothing heat can help alleviate muscle and joint pain, making them feel more comfortable, especially during cold weather. Moreover, heated blankets can provide a safe and warm environment for dogs recovering from surgery or those with specific health conditions like arthritis. For puppies, a heated blanket can mimic the warmth of their littermates, providing them with a sense of security.
