My dog has a cough and diarrhea after boarding. Is it kennel cough?
Thanks for using Petco Pet Education Center, formerly Petcoach. The diarrhea is very common after boarding and can be related to either the food or the stress/excitement of boarding. The thirst is usually secondary (that is, to keep up with the water loss of the diarrhea.) The antibiotics Tylan and metronidazole are commonly prescribed for diarrhea because they restore the gut bacteria balance and have some anti-inflammatory effects in the gut as well. I expect that part o clear up in a few days.
The cough could still be kennel cough. “Kennel cough” is a syndrome that can be caused by about a dozen viruses and bacteria. The current kennel cough vaccine only covers one bacterial cause.
If it is mild, you may not need to do anything. Most dogs clear kennel cough on their own within 4 weeks. If she is not eating, is lethargic, the cough is severe or keeps her (or you) up at night, you need to see your vet for antibiotics and/or a cough suppressant.
Of course coughing can also be: pneumonia, fungal infection, heart disease, bronchitis, and others. So if you are worried at all, see your vet.
Best wishes to you and the pups!
