Balanoposthitis It is a infection that occurs in the glans and foreskin of the dog which is usually green or white, dense and with a bad smell, it is also secreted in abundant quantities, which helps to differentiate it from smegma, which is produced in small quantities.
This infection usually causes discomfort and pain, so the dog will lick excessively. This problem appears due to the introduction of some foreign body in the glans or foreskin capable of causing a irritation and / or injury that will follow from an infection. Balanoposthitis can also be due to canine herpervirus, which produces a chronic infection, or it may even appear because the dog has a too narrow foreskin hole and because of phimosis, which disables the retraction of the foreskin on the glans, which interferes with the flow of urine, for that same might appear pus on the dick of the animal.
