I have heard about the reverse sneeze I think people called it that chihuahua's do sometimes, and some people says their babies do some say they don't. Well how often is normal?? I get so worried when he does it :confused2: It sounds so scary!! He did it in the middle of the night last night at 4am or something. He does it maybe once a day or so lately, usually for about 8 seconds. Is this normal?
