Kennel cough is an upper respiratory disease that is caused by various bacteria and viruses, The most well known one would be Bordetella sp. Kennel cough is a self limiting disease and will go away within 4 weeks even without treatment, We only treat the animal if it has a fever, or if the cough gets so bad that it is coughing almost all the time, or if there is a purulent discharge. You do not need to do anything. Should your dog start coughing constantly or get lethargic or have a purulent discharge, you should take it either to your vet for an exam and cough medicine and antibiotics as needed or to a PetER if your vet is not open. But if your dog is happy and other than coughing occasionally appears not bothered by it, you can wait it out.

    Kennel Cough is typically viral. I recommend putting Tobu in the bathroom while you shower so the steam will help. Typically I recommend a veterinarian to make sure it is kennel cough and to make sure his lungs are clear. If you did not want to take Tobu to a vet then if the coughing gets worse, he becomes lethargic, anorexic or has difficulty breathing he does need a veterinarian. Kennel cough can develop into a secondary bacterial infection and they can get bronchitis or pneumonia with it. Always remember it is contagious so keep him away from other dogs.

    Congratulations on your new addition! Kennel cough is an infection that occurs due to a large number of different infectious bacterial and viral agents. While a previous infection does not make Marley more susceptible to new infections of kennel cough, if he has been around a number of other dogs (dog parks, groomers, kennels), he is more likely to acquire another bout kennel cough. Very mild cases of kennel cough can resolve on their own, but more severe cases can progress to pneumonia. If you are concerned that Marley has been coughing (or his initial cough never completely went away), I recommend taking him to the vet for an exam. There is a chance that he may need another course of antibiotics or medications to dilate his airways to help him along. I hope that he feels better soon!

    Hello. Coughs are quite common in older pets, but that does not mean they are not serious. But the first thing that needs to be done is a good physical examination to listen to the heart for murmurs & the lungs for sounds of congestion. Coughs can be cause by infection, like bronchitis, pnuemonia & tracheobronchitis, heart failure, lung disease, tracheal problems, or from heartworm disease. Once the underlying cause is found, the appropriate medications & treatments can be recommended. I do hope Lucky is feeling better soon & thanks for contacting Petco Pet Education Center, formerly Petcoach.
