Above is a great link. I would recommend that you have your baby checked by a Vet and show them your video. Kennel cough is like a cold and can develop into pneumonia. Collapsed Trachea can be serious and definitely should be checked for. Yorkies have delicate trachea's and this is why it is recommended to use a no choke harness instead of a collar & leash. Buster reverse sneezes when he gets excited or drinks water to fast. Good luck and best wishes.
