Hi there! It is likely Legend has picked up a respiratory infection. He will probably need a course of antibiotics which your veterinarian can prescribe for him after a physical exam. While most respiratory infections are somewhat mild-every now and then one progresses to make them very ill. Best to be seen soon to keep this from happening. My best to you both, hope this helps!
