Croup is characterized by a "barking" cough, [[stridor]], [[hoarseness]], and [[shortness of breath|difficult breathing]] which usually worsens at night.<ref name=Au10/> The "barking" cough is often described as resembling the call of a sea lion.<ref name=Cherry08/>  The stridor is worsened by agitation or [[crying]], and if it can be heard at rest, it may indicate critical narrowing of the airways. As croup worsens, stridor may decrease considerably.<ref name=Au10/>

Other symptoms include fever, [[coryza]] (symptoms typical of the [[common cold]]), and indrawing of the [[chest wall]]–known as [[Hoover's sign (pulmonary)|Hoover's sign]].<ref name=Au10/><ref name=Alberta07>{{cite web |url=http://policyandorders.cw.bc.ca/resource-gallery/Documents/BC%20Children%27s%20Hospital/C-05-07-60048%20Diagnosis%20and%20Management%20of%20Croup.pdf |title=Diagnosis and Management of Croup |work=BC Children's Hospital Division of Pediatric Emergency Medicine Clinical Practice Guidelines |access-date=2020-03-16 |archive-date=2020-06-23 |archive-url=https://web.archive.org/web/20200623003518/http://policyandorders.cw.bc.ca/resource-gallery/Documents/BC%20Children%27s%20Hospital/C-05-07-60048%20Diagnosis%20and%20Management%20of%20Croup.pdf |url-status=dead }}</ref>  [[Drooling]] or a very sick appearance can indicate other medical conditions, such as [[epiglottitis]] or [[tracheitis]].<ref name=Alberta07/>
