How To Clean Dog Smegma: Step-by-Step Guide

As dog owners, we’ve all experienced the grossest things imaginable for a pet owner. From diarrhea on the carpet, vomit on the couch, stinky anal glands, and more – we’ve all been there.

But do you know how to clean dog smegma? Or do you have any idea what it is in the first place?

In this post, I will delve into this grooming task together with all the basic facts you need to know.

What is dog smegma?

Smegma is a biological discharge on a canine’s penis. This is typically normal but there are some diseases and infections associated with it.

Generally, dog smegma is a combination of dead skin cells, moisture, mucus, oils, and other natural substances in your dog’s body.

It serves as a lubricant to the dog’s reproductive organ during mating. Short to say, it’s a normal discharge as long as it’s not dripping, changing in color, or developing a strong scent.

The normal color of a dog’s smegma is yellowish-white. However, some dogs will have a greenish color, which may or may not indicate the presence of an infection.

Nevertheless, the shade of a dog’s smegma varies per canine.

When dog smegma becomes a problem

Most of the time, dog smegma isn’t a cause of concern. However, if the penis’ sheath becomes swollen or there’s a dripping discharge, that’s the time you should worry.

Aside from that, a foul smell on your male dog’s smegma can be a sign of infection. It’s best to bring the dog to the vet for proper diagnosis and treatment.

To identify the problem with your dog’s smegma, the vet will run a physical check on the canine’s genitalia.

If need be, the veterinarian will also conduct blood work and sampling for bacterial culture.

An ultrasound could be done for further examination and if the previous tests didn’t yield specific answers.

Steps to clean smegma in dogs

Things you need:

  • Clean cloth
  • Clean water
  • Warm, salty water
  • Puppy wipes


Step 1. Check your dog’s genitalia

Before you perform any cleaning steps, you should conduct a quick visual check of your dog’s genitalia area.

This will give you an idea if there are injuries, swelling, or anything unusual.

If there’s a crusty buildup on the sheath, wipe it with a cloth soaked in warm, salty water. This will soften up the crusts and disinfect your dog’s genitals.

Take note that you should only use salt and not any soaps or alcohol that will sting.

Step 2. Clean the genitals

After that, pull your dog’s sheath gently to expose the penis. You need to wipe this with a cloth soaked in clean water.

You can also use non-scented puppy wipes if you don’t want the mess of wringing a cloth. Keep wiping until you’ve removed all the smegma deposits.

For sure, your dog will try to escape as you do this. I suggest asking someone to assist you in restraining the pooch.

Also, be gentle because your dog’s genitals are very sensitive and prone to injuries.

Step 3. Rinse it well

If wiping isn’t enough to remove the smegma deposits, you can take your dog to the bathroom. Give its genitals a quick rinse using running water.

There’s no need to use soaps or shampoo, just warm water should be enough. While dog shampoos are safe, it will sting if it gets into your dog’s penis.

Step 4. Pat it dry

Once you’re done cleaning, it’s important to wipe your dog’s genital area dry. This will prevent the accumulation of bacteria and odor.

I recommend making smegma cleaning a part of your dog’s grooming session. You can easily do this during your dog’s baths.

If your dog’s smegma production is strong, it could smear into your furniture. It’s important to clean this or your house will stink.

My easy solution here is an enzymatic cleaner. I simply apply a small amount on a cloth and wipe it where my dog wiped his smegma.

If you don’t have this, an equal solution of vinegar and water will do, but make sure that you perform a spot test on a hidden part of the furniture as the vinegar may react harshly on some wood finishes.

Anyway, most cleaners will do here as long as it’s not toxic for dogs and kids.

Why does dog smegma smell so bad?

If your dog’s smegma is foul-smelling than normal, it’s usually a sign of an infection. This could be accompanied by swelling, excessive licking on the sheath, and a dripping discharge.

In this case, cleaning alone at home isn’t enough. You should bring the doggo to the veterinarian immediately to curb the infection.

Most of the time, normal smegma discharge doesn’t require special intervention. However, the buildup may dry and crust around the dog’s genital area.

Is it normal for a male dog to have discharge?

This depends on the color and type of discharge. Smegma, for one, is typically normal unless it develops an infection.

Excessive licking and a foul odor emanating from the dog’s penis is often a red flag for infection. It’s best to bring your dog to the vet if the symptoms don’t go away for a few days.

Moreover, a bloody discharge from a male dog should always be considered serious. This could point to a condition called benign prostatic hypertrophy (BPH).

While non-cancerous, it can cause an enlargement of the dog’s prostate gland, which can lead to other conditions.

Usually, neutering is the most effective treatment for this problem. Please read here why is my dog so hyper all of sudden.

In general, dogs with bloody discharge should be brought to the vet’s clinic as soon as possible.

Meanwhile, a pus-like discharge can be due to a lot of reasons. It can be a sign of erectile disorder in canines as well as prostatic disease, urinary tract stones, blood-clotting disorders, and reproductive tract infection.

It’s also possible that a foreign matter got dislodged in your dog’s prepuce or the skin that covers the canine’s penis.

You should also consider the possibility of traumatic injury near the genital area.

Why is my dog’s sperm green?

A dog with a greenish sperm color could be suffering from a prostate infection. You must bring the dog to the vet for an examination.

This is especially urgent if you’re trying to mate your dog with another canine. You wouldn’t want the infection to transfer to another dog or worsen due to mating.

Take note that infections like these won’t go away on their own. It will just worsen every time as long as your dog isn’t getting the proper veterinary care.

Can dogs get STDs?

Yes, canines can contract sexually transmitted diseases (STDs) when mating with another dog.

If you notice that your dog is licking its genitals too much after mating, you should observe it closely. Check its genitals and see if inflammation or sores is building up.

If you suspect that your doggo has an STD, you should bring it to the vet immediately.

The vet will conduct blood and sampling tests to identify the exact infection that your dog contracted.

You may notice that your pooch is self-cleaning its genitals, but it’s best to wash it from time to time. Water should be enough.

But if there’s a buildup around the genitalia, you can ask the vet for a cleaning agent.

You should never use soap or even dog shampoo to clean your dog’s reproductive organ because it will sting.
