In general, younger animals might be more likely to develop infectious or foreign body pneumonias, while older animals develop bronchitis, neoplasia, airway collapse, and perhaps aspiration pneumonia. Dogs with eosinophilic or fungal pneumonia also tend to be young to middle‐aged. Asthma/bronchitis seems to affect cats of all ages, although perhaps the eosinophilic form is more common in younger animals. Cervical tracheal collapse might affect younger dogs, while older dogs get both tracheal collapse and bronchomalacia.

The breeds affected depend on the underlying case of cough. For example, an older Retriever‐type dog is likely to develop laryngeal paralysis and subsequent aspiration pneumonia, while aspiration in a brachycephalic breed often happens at a young age. Tracheal collapse affects toy and small breed dogs, while chronic bronchitis and bronchomalacia can affect any size breed of dog.
