If your dog is hacking away or constantly making noises that make it sound like he's choking on something, he may have a case of kennel cough, or canine infectious tracheobronchitis. Although kennel cough can sound terrible, most of the time it is not a serious condition, and most dogs will recover without treatment.
Dogs can have stridor, or croupy breathing, which has a raspy, high-pitched sound. Dogs can make this noise when they exercise. If the onset of this sound is sudden, however, this could be a sign that something is lodged in the dog's voice box. If a dog is wheezing, the trachea or bronchi could be having spasms or narrowing.
