Why is my dog following me panting and acting weird?

Your dog may be following you and panting due to anxiety, excitement, or stress. Changes in environment, routine, or even the weather can affect their behavior. If your dog seems excessively restless or uncomfortable, it might be a sign of an underlying health issue, so observing for other symptoms and consulting a veterinarian is advisable. Additionally, ensuring they have access to water and a comfortable space can help alleviate their distress.
