If your puppy got a kennel cough vaccine, you can see some mild symptoms of the disease after receiving the vaccine. This can be normal, and it's good that he is playful, eating, and drinking. It could also be he picked up a respiratory infection at the vet clinic. Keep an eye on him for now, and if the sneezing and heavy breathing do not improve in the next 48 hours, or he stops eating, drinking, and becomes lethargic, then I would take him into the vet. Good luck, I hope this helps!
