My dog has kennel cough and is throwing up. Why won't he eat or drink?
If the vomiting occurs at the end of a coughing fit then it is likely to be related to the kennel cough. I know it can be pretty scary, and make them quite poorly too. However, the worse is over in 3 days then things start to look a bit better. Kennel cough has its own course of about a week but can last 10 days or even a bit longer if the immune system is a bit depressed for other reasons.Have you tried to offer small amount of food throughout the day ? Something like Hill’s A/D or RCW recovery that you could mix with water and then just offer lukewarm. It is a diet that is quite rich in energy so he would not need to eat as much as his normal food. The most important thing in the acute phase, the first 3-4 days from when its starts, is supportive care. Make sure Peanut rests, encourage him to eat a palatable diet, keep comfortable, warm but not too hot. If you are worried, that he is vomiting all the time, he is too lethargic, have him checked over, better to be safer than sorry.
