A puppy’s ear pus may be caused by otitis media, otitis externa, ear eczema, and other diseases, or by other conditions. Puppy otitis media is usually caused by bacterial infection and can follow colds or sinusitis, typically causing ear pain and watery or pus discharge.
Puppy otitis externa is usually caused by Staphylococcus aureus infection, while ear eczema is usually from allergy or mental factors. Different causes need different treatments, so if ear pus is found, take the dog to a vet promptly to diagnose and treat appropriately.
