If your dog is constantly licking his penis, or the organ appears inflamed, he could suffer from balanoposthitis. This disorder more often affects young, intact males. It causes a lot of discomfort for your dog, so take him to the vet as soon as possible.
Symptoms of the condition in dogs includes:
- Pus discharging from the penis.
- Bloody penile discharge.
- Penile inflammation.
- Lesions on the penis.
If the penis is infected, the dog may spike a fever, stop eating and appear lethargic.
Diagnosis and Treatment
Your vet will examine your dog's penis, looking for the cause of the inflammation. Possible causes include foreign bodies in the penis, trauma, urinary tract infections or tumors. She probably will have to sedate your pet, and possibly anesthetize him to conduct an examination. She'll take samples of any discharge for a bacterial culture to identify the specific organisms causing infection. Blood tests and a urinalysis also will be conducted. The urine for testing comes straight from the bladder, so it doesn't become contaminated with penile discharge.
Treatment consists of flushing out the penis with an antiseptic. Your vet can show you how to do this at home. If there's an infection, your vet likely will prescribe antibiotics. She also may prescribe an antibiotic ointment that you must place into your dog's prepuce -- or penile sheath -- for a week or so. Your dog may have to wear an Elizabethan collar until the infection abates so that he doesn't keep licking his genitals.
If the inflammation occurs because of a foreign object or tumor, your dog may require surgery.
Balanoposthitis tends to recur. Neutering your dog can reduce the odds of recurrence, although it doesn't eliminate it entirely. That's because neutering cuts down on penile secretions, but they still exist. Regularly flushing out the prepuce with antiseptic solution helps prevent the condition.
