Shmoo is still very playful.. he still coughs but only when he gets too excited. At night he sometimes snores and coughs as well. He was more tired when we put him on the enalipril but now he seems just fine (with the occasional cough). He loves to go on long walks still, play, and run around the yard. He only likes soft food now and I feel he eats less than he did before the whole kennel cough ordeal.
Thank you for the cardiologist information, I will definitely look into that
