A. Bear in mind Kennel cough is a self limiting condition, which means it usually resolve itself without treatment BUT it can take up to 2 weeks. In the meantime continue giving antibiotics and cough medicine as often as prescribed.
Coconut oil is not likely to do much difference unfortunately. It's not going to harm him but I cannot recommend the treatment with coconut oil either.
If he is happy in himself and eating fine, try being patient and let time do it's job.
