I agree with ag in saying he is too young for you to have him already. My guys hicup all the time and it sounds bad but they are ok. Because of your pups age I would take him back into the vet and discuss any concerns you may have. Some vets are pretty good and mybe only bill you for a follow up because of the kennel cough
