Colloidal Silver For Dogs

As much as we love our canine friends and treat them as an equal member of the family, we must admit that dogs essentially live a dirty life. They love to roam and run outside and chase other animals. At some point, your dog is most likely going to face an infection. When this happens, you might be interested in looking into natural antibiotics for dogs instead of going for human-made antibiotics. One popular option is colloidal silver for dogs. 

Colloidal silver for dogs is a relatively safe, fast way to fight infections. It can fight bacterial, fungal, and viral infections.

Also, it has other health benefits, such as boosting your dog’s immune system and their general health and well-being.

If your veterinarian approves the use of colloidal silver for your dog, the benefits can be plentiful, and the knowledge that you’ve treated your canine companion in a more natural way will give you peace of mind.

What Is Colloidal Silver For Dogs?

Colloidal silver for dogs is a natural antibiotic that can be used to fight a variety of infections, such as infections of the ears and skin, a sore throat, and even yeast infections.

Aside from being a natural antibiotic, it also has antiseptic, antifungal, and disinfectant properties. It is made of submicroscopic pieces of silver particles broken down into a liquid base.

Particles of silver ions created with a micro-particle colloidal silver generator are small enough to penetrate on a molecular level and destroy all types of pathogens, such as bacteria, fungal spores, viruses, and parasites. The idea is that colloidal silver hinders a pathogen’s ability to breathe, and kills it within a few minutes.

Pets being treated with colloidal silver typically return back to good health within a few days.

From the late 1800s to 1938, colloidal gold and colloidal silver spray were regularly prescribed to treat various different infections and diseases. After human-made antibiotics such as penicillin were invented in the late 1930s and onwards, colloidal silver became less popular.

A Cure-All? The Many Uses Of Colloidal Silver For Dogs

Although colloidal silver for dogs can be used to treat many different infections, it’s important to note that it is not necessarily a cure-all.

Colloidal Silver For Dogs uses

If you are considering using colloidal silver for your dog, you should contact your vet first. With that in mind, let’s look at some of the possible uses of colloidal silver.


When colloidal silver is turned into a mist by using a nebulizer, it can be used to treat certain respiratory problems such as pneumonia, bronchitis, and asthma.


Colloidal silver can be used to treat eye problems, such as inflammation and infection. It is painless, so colloidal silver drops can be applied directly to your dog’s eyes.


Topically, colloidal silver can be used for wounds, burns, and infections such as ringworm. It has a soothing effect that repairs tissues.


Colloidal silver drops applied directly to a dog’s ears can fight off ear infections.


Colloidal silver is a natural antibiotic for dogs and can be used to fight any viral, bacterial, or fungal infection. It can also be used as a preventative measure.

A Bacteria Killing Machine! Colloidal Silver: A Natural Antibiotic For Dogs

When we say natural antibiotic for dogs, we mean that it is a natural substance that can be used to fight different infections and diseases, such as ear infections.

Disclaimer: Colloidal silver for dogs is not actually an antibiotic, such as penicillin. For this reason, some vets totally support the use of colloidal silver, whereas some prefer to stick with human-made antibiotics.

That being said, colloidal silver for dogs is a bacteria-killing machine! It can fight so many different infections without the use of a human-made chemical antibiotic.

Natural Antibiotics For Dogs: What Pet Natural Remedies Does It Offer?

Natural antibiotics for dogs provide an array of different benefits.

Colloidal silver, oregano oil, manuka honey, apple cider vinegar, and certified-organic garlic are all examples of natural antibiotics for dogs. One of the biggest benefits of these natural antibiotics is an immune system boost.

Human-made antibiotics can actually harm your dog’s immune system. Also, these natural antibiotics can be used to fight various infections, such as Lyme disease and urinary tract infections.

Fighting Bacterial Infections: Colloidal Silver Vs. Other Natural Antibiotics For Dogs

Colloidal silver is a great natural antibiotic for dogs, but what other natural antibiotics are available?

Manuka Honey

Manuka honey comes from Australia and New Zealand, from the nectar of the Manuka tree.

It can be used topically as a natural antibiotic for dogs and will treat many different infections. Manuka honey may even be able to be used against antibiotic-resistant superbugs, such as MRSA. All honey contains hydrogen peroxide, an antiseptic, but unfortunately a temperamental antiseptic that can easily be destroyed.

However, a New Zealand biochemist discovered that when you remove hydrogen peroxide from Manuka honey, other powerful antibacterial factors remain.

Oregano Oil

Oregano oil has antiviral, antibacterial, antiparasitic, and antifungal properties, making it an excellent natural antibiotic for dogs. It can be applied topically, orally, or diffused – but never undiluted oregano oil. The best ratio for oregano oil would be one drop of oregano oil mixed into a teaspoon of coconut oil.

What Science And Other Vets Say About Colloidal Silver

Overall, vets and science are conflicted about the use of colloidal silver for dogs.

There are plenty of benefits, but there are also some significant risks, which we will go through below. The general consensus is that it is much safer to administer colloidal silver in a topical form rather than orally.

When used orally, vets and researchers highly recommend monitoring the dosage carefully and avoiding using too much colloidal silver. The FDA has ordered different organizations to stop claiming colloidal silver to be an effective antibiotic.

From Ear Infections To Skin Infections: How Much Time Does Colloidal Silver Take To Actually Work?

Colloidal Silver For Dogs effects

On average, colloidal silver takes about five days for the initial benefits to be apparent.

By day ten, most dogs who have been administered colloidal silver will be healed of their initial complaint. When treating an infection, colloidal silver should be administered two to three times per day for ten days. At that point, treatment is complete.

Some dogs who are being treated with colloidal silver will begin to show signs of sluggishness about three to four days into treatment. This occurs because eliminatory organs become overloaded trying to push toxins out of the body. To avoid this, you should encourage your dog to intake more fluids during treatment.

There are multiple ways you could encourage fluid intake.

You could add chicken broth to your dog’s meals or place a small water bowl of chicken broth next to your dog’s food bowl. You could also offer your dog green tea, rooibos tea, or parsley drinking water.

When you keep your dog’s fluid levels up, you are helping them efficiently eliminate toxins from their body.

How To Use This Treatment On Cats And Dogs

You can use colloidal silver on your dogs and cats orally, topically, or nebulized.

To administer colloidal silver orally, simply drop the colloidal silver into your pet’s mouth multiple times per day for ten days. It tastes like a water bowl of regular drinking water, so your pet should have no problem taking it.

Topically, to treat insect bites and other skin conditions, you can use colloidal silver in a spray bottle to clean the infected area.

For skin conditions, you can either spray the colloidal silver on or you could use it as a compress. It doesn’t sting or burn, so you don’t have to worry about causing discomfort to your pet.

Nebulizing colloidal silver can be used when you are wishing to treat the lungs. Nebulizing should be done for fifteen minutes.

For ear and eye infections, you can put a few drops of the colloidal silver in the eyes and ears multiple times a day for up to ten days. This will not cause discomfort.

Colloidal Silver Dosage For Dogs

Colloidal silver dosage for dogs depends on the size of your dog, rather than their age in years. Medium-sized dogs, for example, need a higher dosage of a colloidal silver solution than smaller dogs.

The general guidelines are as follows.

Note: All treatments all given 2-3 times per day, for ten days.

  • 2 to 10 pounds – 1/16 teaspoons
  • 11 to 25 pounds – 1/8 teaspoons
  • 26 to 40 pounds – 1/4 teaspoons
  • 41 to 55 pounds – 1/2 teaspoons
  • 56 to 80 pounds – 3/4 teaspoons
  • 81 to 100 pounds – 1 teaspoons
  • 101 to 150 pounds – 1 1/4 teaspoons
  • 151 to 200 pounds and over – 1 1/2 teaspoons

It is important to note that colloidal silver, like human-made antibiotics, will reduce the amount of natural beneficial flora in the gut.

When using colloidal silver as a natural antibiotic for dogs, it is important to follow up with probiotics, and ideally being with prebiotics) to help build up the good bacteria levels in your dog.

Be sure to purchase your colloidal silver from a reputable source. It is sold in different degrees of quality, so before you make a purchase, be sure to do your research to find the best brands.

It is true that colloidal silver can be more effective than man-made antibiotics, for several different reasons. Colloidal silver can typically kill an infection much faster than a human-made antibiotic.

The downside to this is that sometimes the kill will happen too fast, which is what causes sluggishness in dogs. To combat this, start with smaller doses and work your way up to the recommended dosage.
