You & Your Puppy: Dealing with Kennel Cough
“What’s up with my pup?? He keeps coughing like he’s trying to bring up a hairball….”

There’s a strong possibility that if you purchased your puppy from a pet store or adopted from a local shelter your pup may be experiencing the following symptoms: a runny nose, an occasional wet sneeze, and a hacking cough that sounds like an attempt to bring something up. If this description fits, then your puppy may have a case of infectious tracheobronchitis… otherwise known as “kennel cough.”
What is Kennel Cough?
Infectious tracheobronchitis is extremely common, especially in shelters, pet shops, boarding kennels and even veterinary hospitals. It is an infection caused by a virus (usually parainfluenza although other viruses can play a role), AND a bacteria (usually Bordetella bronchiseptica) that infect the nasal cavity, trachea (windpipe) and upper airways. The infection tends to cause a significant amount of congestion, causing the puppy to have a productive cough. Owners will often report that their puppy is trying to bring something up, but with no success. In fact, they are bringing something up and are swallowing the evidence.
The virus is very highly contagious. This is why it’s such a problem in enclosed environments where multiple pups are housed close together. When an infected puppy coughs or sneezes, the virus aerosolizes into the air and easily infects other individuals close by. In shelters and pet shops, puppies are often handled by multiple individuals who inadvertently spread the germs on their hands and clothes. By nature, puppies are more susceptible to infection because of their immature immune systems.
Here are some facts you should know about infectious tracheobronchitis:
1) Symptoms develop within 2-14 days after the puppy is exposed to the germs.
2) Most symptoms last about 14-20 days in typical cases.
3) An infected animal can shed the bacteria for as long as 6-14 WEEKS. This is not a type-o. Antibiotics DO NOT always reduce the time of bacterial shedding.
How is kennel cough treated?
Most cases of kennel cough are what doctors call “self limiting.” This means that the symptoms are mild enough that the puppy just requires supportive care such as a nutritious diet, plenty of fresh water, a warm environment, and a humidifier/vaporizer to help loosen congestion.
More severe cases may require antibiotics, expectorants to loosen congestion, and sometimes bronchodilators to open up congested airways. Rarely, infected pups can develop pneumonia which can be life threatening. Those pups typically require hospitalization to receive fluids and medications through an IV. Sometimes they may also need nebulization treatments and oxygen supplementation. The veterinarian will help determine what is needed based on the puppy’s physical exam findings and history.
One thing that the veterinarians end up stressing to owners with kennel cough puppies is that even with treatment, your pup will still likely cough. This does NOT necessarily mean your puppy is not improving, or that the infection is not being treated properly. The congestion that the infection causes needs to be cleared from the body, and coughing is the main mechanism by which this gets done. Cough suppressants are only used in patients that are very uncomfortable from excessive hacking and NEVER used in patients with suspected pneumonia.
ALWAYS notify the veterinarian if your puppy:
1) loses his/her appetite or stops drinking
2) seems overly sluggish or lethargic
3) is having trouble breathing (rapid, shallow breaths or you can see the belly move with each breath).
How is kennel cough prevented?
True prevention can only be obtained through isolation of your puppy from other dogs. When this cannot be achieved, vaccination (the “Bordetella vaccine”) is recommended. If you have purchased your puppy from a pet store, it is likely the pup has alrerady received a kennel cough vaccination. So, why then, could your pup have an infection?
Kennel cough vaccinations cannot and do not prevent infection. They only help to decrease the severity of the disease (much like flu vaccines in people). There are two types of vaccines available. The injectable requires two doses, 3-4 weeks apart. Protection typically develops within 1-2 weeks.
The intranasal vaccine is considered by most to be the best option because only one dose is needed and protection develops within 3-4 days of vaccination. There are a couple of drawbacks, however. First, your pet can actually SHED VIRUS that can cause infection in other dogs for up to 72 hours after vaccination. Secondly, some pups might actually develop some symptoms of kennel cough themselves for a few days.
If your puppy will be kenneled regularly, a participant at dog shows/agility trails, or a “frequent flier” at a grooming facility, the Bordetella vaccination should be administered every 6 months. Ask the veterinarian about your pup’s recommended protocol.
THE BIG POINTS:
1) If your pup has been diagnosed with kennel cough, make sure it is eating, drinking, playful, and breathing comfortably. If not, CONTACT OUR OFFICE.
2) Provide a humidifier/vaporizer in the room where your puppy sleeps, especially if in the colder winter months. Consider bringing the pup into the bathroom while you take a steamy shower to help ease breathing. Keep your puppy’s nostrils free of debris.
3) If the veterinarian prescribes medications for your pup, make sure to follow directions and administer ALL antibiotics for the ENTIRE time, even if symptoms resolve before then.
3) If your puppy has an infection, please realize that he/she is CONTAGIOUS for up to 3 MONTHS. Do your best to isolate your puppy from other dogs and do not take him/her to public places such as the groomer, boarding kennel, pet stores, doggie parks, or doggie day care.
4) Expect coughing (especially after excitement and exercise) for up to 8 WEEKS. Severe coughing should be re-evaluated by the veterinarian. Minor coughing is expected during the recovery process.
5) Vaccines DO NOT PREVENT INFECTION. They help reduce the severity of symptoms.
