Dog Coughs After Drinking Water. It is not uncommon for dogs to cough after drinking water. It is important that as responsible owners, to pay attention to these occurrences and take action immediately as some conditions may look harmless but can be fatal.
The larynx is normally closed when food is swallowed, to stop food particles from getting into the trachea. This way, the pooch can’t gulp strongly. But, if the cough happens even when the dog hasn’t eaten or drunk anything, it may be kennel cough.
