My dog has penis discharge, fishy breath, and dark spots. Normal?

Updated on September 23rd, 2025

Pet's info: Dog | Soft Coated Wheaten Terrier | Male | unneutered | 4 months and 28 days old | 13 lbs

Is the discharge my pet has on his penis normal? He constantly licks and leaves his breath smelling very foul, fish like. Also he has dark spot markings near his nipples...they just appeared...is that flea related or a rash?

If his breath smells like fish I would recommend having his anal glands checked. I would also recommend having your veterinarian shave the hair off of his prepuce and check a urine sample. That way we can determine if this discharge is anything to be concerned about. Thank you for using Petco Pet Education Center, formerly Petcoach.
