These signs could be compatible with a respiratory tract inflammation/infection or potentially could be related to heart disease. Considering the lethargy, a systemic sign, I would recommend a check up as soon as possible to determine the underlying cause and establish appropriate treatment. Antibiotics may be needed. Please do not hesitate to contact us again on the forum or by requesting a consultation (where you can post pictures ) if you have any more questions or to discuss it any further.

I'm sorry to hear that your dog hasn't been feeling well. Coughing and lethargy could be a sign of underlying diseases like heart disease, heartworm disease, chronic bronchitis, cancer, among others. I'm glad to hear that he only had one episode of coughing, but the ongoing lethargy is a bit more concerning. I do recommend taking him to the vet for an exam and possibly for chest x-rays to get to the bottom of this issue. Better safe than sorry. I hope that all goes well!
