Why do dogs cough?

Dogs are also most prone to coughing when the weather is too warm and the temperature difference between morning and evening is too great. Some coughs are nothing to worry about, for example, when they have just woken up or are irritated. If there is a respiratory infection, your dog may have a cough, but other illnesses can also cause it, so it is advisable to take your dog to hospital for diagnosis and treatment if the cough is frequent.
