Why Is A Green Discharge Coming From My Male Dogs Penis?

If you have ever seen a green discharge coming out of your dog’s penis, you may be wondering if there is anything wrong with him.

Discharge can come out of any part of the body, but we will focus on the penis here.

There are many different types of discharges that can occur in this area.

Some are normal and some require immediate medical attention.

Here is a brief overview of these common types of discharges.

Why Is A Green Discharge Coming From My Male Dogs Penis

White Discharge (Bacterial Infection)

This type of discharge is caused by bacteria and usually appears as a white substance.

It often comes out when the dog urinates.

This type of discharge can also appear as a yellowish-white color as well.

The severity of the infection depends on how long it has been present and how much bacteria is involved.

A small amount of white discharge should be expected at least once every few days while a high amount of bacteria can lead to more serious problems such as kidney failure.

Yellow Discharge (Allergic Reaction)

A yellow discharge can also be found in the penis.

It is caused by an allergy to penile secretions.

This type of discharge is not harmful and should disappear within a day or two after treatment is started.

If the yellow discharge does not go away, it might be due to a bacterial infection that requires antibiotic treatment.

Red Discharge (Hemorrhage)

The red discharge of the penis is another sign of an infection.

It consists of blood mixed with other substances.

This type of discharge is extremely dangerous and needs immediate medical attention.

If left untreated, the bleeding can become worse and even lead to death.

Green Discharge (Penile Cancer)

This type of discharge is very rare but still possible.

Penile cancer can affect humans as well as dogs and cats.

It starts as a dark spot on the skin of the penis.

As the disease progresses, the discharge becomes green.

When this happens, the chances of dying from the cancer increase significantly.

What could be the cause?

There are a lot of different things that can cause a green discharge coming from a dog’s penis.

One of the most common causes is an infection, but other possible culprits include allergies and yeast infections.

A vet will need to examine your dog and conduct tests in order to determine the exact cause of his green discharge.

1. Infection

An infection is one of the most likely causes of a green discharge coming from a dog’s penis.

This type of discharge can come from many different places on the body – anywhere where bacteria can thrive.

The most common place that people see a green discharge coming from their dogs’ penises is around the anus, so this area should always be examined by a veterinarian.

The bacteria that cause green discharges can come from the dog’s own feces.

They also can come from outside sources like soil, water, food, bedding, and toys.

When examining your dog, the vet will check his rectum for signs of inflammation, redness, and pus.

He might also look at the anal glands, which produce mucus that usually comes out as white or clear.

The vet will take samples of these areas and send them to the lab for testing.

In some cases, the vet may find bacteria inside the dog’s prostate, and he will perform a biopsy to remove any infected tissue.

The vet will then prescribe antibiotics to treat the infection.

2. Allergies

Allergic reactions can cause a green discharge coming from a dog’s penis.

These reactions are often caused by foods or chemicals that a dog has been exposed to.

Some examples of allergens that can trigger this type of reaction include pollen, dust mites, mold, dander, and even fleas.

If your dog suffers from an allergy, he may experience symptoms such as itching, scratching, sneezing, coughing, runny nose, and hives.

These symptoms are similar to those of an infection, but they don’t require treatment with antibiotics.

Instead, the vet will recommend antihistamines to help reduce the itchiness.

3. Yeast Infections

A yeast infection is another possible cause of a green discharge coming from a dog’s penis.

In fact, it’s one of the most common types of yeast infections that occur in both humans and animals.

When a yeast infection occurs, tiny fungus spores called candida albicans grow in the dog’s body.

The spores feed on the dog’s blood sugar, causing the dog to become ill with diarrhea, vomiting, weight loss, and fever.

A yeast infection can happen anytime during the dog’s life, but it’s more common in puppies who haven’t yet begun eating solid food.

As soon as the puppy begins eating solid food, the vet will begin treating the dog with antifungal medications.

4. Chlamydia

Chlamydia is another disease that can cause a green discharge coming from a dog’s penis.

Although chlamydia isn’t commonly found in dogs, it does affect humans.

People can contract this disease through sexual contact with an infected person.

Once someone contracts the disease, he may notice symptoms such as a burning sensation when urinating, a thick yellowish-green discharge, pain while urinating, and painful sex.

In dogs, the only way to transmit the disease is through breeding.

If a female dog becomes pregnant and her cervix swells up, she may pass the disease onto her offspring.

However, she won’t show any symptoms until after giving birth, so she doesn’t know that she carries the disease.

Is this discharge normal?

It depends on what kind of discharge you are talking about.

While some types of discharges can indicate that one of your pet’s organs is not working properly, others are more benign and just part of the process of urination.

The following list describes common types of discharges:

  • White discharge: This type of discharge occurs when urine flows out of the urethra without the help of muscles in the penis. This is often caused by an injury to the bladder, such as from a urinary tract infection (UTI).
  • Yellow discharge: This type of discharge happens when bacteria in the urine combines with ammonia to make a yellowish substance that comes out of the urethra. Yellow discharge is usually associated with UTIs. Some medications can also result in yellow discharge.
  • Green discharge: This type of discharge occurs when bacteria in the urine combine with ammonia to make a green substance that comes out of the urethra. This is often associated with UTIs but can also be caused by other infections, including yeast infections.
  • Clear discharge: Clear discharges are relatively uncommon and occur when the urethra isn’t blocked up at all. Often, clear discharges happen because of a blockage in the prostate gland, which produces most of the fluid that makes up semen.

The list above doesn’t include every possible type of discharge your pet might have.

For example, urine may sometimes appear red or brown when it comes out of the penis, too.

It may also come out foamy and frothy, or look like blood.

In addition, some people consider any urine that smells foul to be a “bad” smell.

As always, talk to your vet before jumping to conclusions!

When should you be concerned?

A green discharge coming from your male dogs penis is not necessarily a sign that something is wrong.

In fact, it could be completely normal and nothing to worry about.

A green discharge is usually caused by bacteria and other microorganisms that are present in the environment, such as dirt and dust.

It can also be caused by a pet owner who does not properly wash their hands after handling their pet.

This can lead to bacteria being transferred directly into a dog’s genitals.

The same thing goes for any person who has come into contact with your dog and then touches his genitals without washing their hands first.

The most common types of bacteria that cause a green discharge are staphylococcus and streptococcus.

These two types of bacteria can cause infections and skin conditions like ringworms, abscesses, and dermatitis.

However, these bacteria are also found on humans’ bodies, so they are not exclusive to animals.

They just happen to be more prevalent in dog penises because of the constant licking and grooming that occurs.

So how do you know if your dog has a green discharge coming from his penis?

How can you treat it at home?

There are some home remedies that may help alleviate this issue.

You can also try to avoid any possible causes by feeding your dog with fresh foods and making sure he stays hydrated.

When in doubt, take your dog to a veterinarian as soon as possible.

When to see the vet

There are so many potential causes for a green discharge coming out of your dog’s penis that it is important to take it seriously and contact a veterinarian as soon as possible if you suspect that your dog has an issue.

It’s also important to note that while some of these issues can be treated in-house by using over-the-counter medications, others will require a trip to the vet for more advanced treatments.

What does “green discharge” mean?

The most common type of discharge coming from your dog’s penis is called a “green discharge.”

This is because it is usually a color similar to that of grass (although it can also look yellowish).

Green discharges typically indicate that there is an infection present, but they can also come from allergies, yeast infections, skin irritations, and other conditions.

In addition, the color of a green discharge can vary quite a bit depending on what is causing the discharge.

A green discharge can be very difficult to distinguish from normal urine, which makes it even more challenging to diagnose.

What are the symptoms of a green discharge?

Some of the most common signs of a green discharge include:

  • Foul odor
  • Redness around the opening of the penis
  • Pain when urinating
  • Eruption of scabs on the penile area

In addition, if you notice any of the following signs, it’s time to make an appointment with your vet:

  • Lethargy
  • Difficulty breathing
  • Rapid heart rate
  • Bleeding
  • Seizures
  • Vomiting
  • Dilated pupils
  • Loss of consciousness

Does this sound like my dog?

If you think that your dog might have a green discharge coming out of his penis, it’s best to bring him into the office immediately.

You should never assume that your dog is okay just because he hasn’t shown any obvious signs of illness.

You don’t want to wait too long to bring him in, as this can lead to complications that are much harder to treat than they would otherwise be.

Is it safe to give my pet medication at home?

There are a variety of different types of medications that you can use to treat a green discharge.

However, not all of them can be used at home without a prescription.

Most of the time, over-the-counter medications will work fine to treat a green discharge.

These medications include:

  • Hydrocortisone cream
  • Phenylpropanolamine hydrochloride
  • Antibiotics such as amoxicillin
  • Nitrofurazone
  • Other anti-inflammatory medications

However, some of these medications may only help to reduce the amount of discharge that comes out of your dog’s penis, rather than actually treating the condition itself.

For example, one of the most commonly used anti-inflammatory medications is phenylpropanolamine hydrochloride, but this drug only helps to prevent inflammation and irritation.

What should I do if my dog has a green discharge?

If you think that your dog has a green discharge coming out of his penis, you need to get him to the vet right away.
The sooner you get your dog to the vet, the better chance you have of getting the treatment you need.


A green discharge coming from your dog’s penis is not something that should alarm you.

It doesn’t mean that he is in danger of death or getting sick, but it does indicate that something is wrong and needs to be addressed immediately.

You should never assume that everything is fine just because your dog doesn’t seem to be struggling too much.

You need to take him to a vet as soon as possible so that they can check things out, and hopefully give you some answers.

The following article will discuss what causes a green discharge coming from your dog’s penis, how to tell if this is normal, and when it might be time to see the vet.
