A few more questions:
How much does he weigh?
Has he had a recent heartworm test?
Is he on heartworm prevention?
If it were an allergic cough the medication would be working by now. Heartworms also cause a cough, so I just wanted to be sure he was covered there - sounds like he is. The other causes of cough in a young dog is an infection or certain parasites. I would definitely call your vet and let them know things haven't improved. They may want to place him on an antibiotic. There are other infections that can cause a cough besides kennel cough, so it may be something else.
Please let me know if you have more questions,
