Colloidal Silver For Dogs – Does It Really Work?

Is colloidal silver for dogs safe?

Welcome to our complete guide to colloidal silver for dogs! In recent years, colloidal silver for dogs has increased rapidly in popularity.  It has been said to cure everything from coughs, to infections, to skin allergies.  However, is colloidal silver actually effective for dogs? And, more importantly, is it even safe?

In this article, we’ll explore just what exactly colloidal silver is and how it might be used for dogs. On top of this, we’ll also answer one of the most important questions of all – does it really work?

What is Colloidal Silver for Dogs?

Colloidal silver is created by immersing extremely small particles of silver into a liquid solution.  The pieces of silver are often so small that you cannot visibly see them.

Colloidal silver as a medical treatment has actually been around for a long time.  The earliest documentation of colloidal silver was in 400 BC, when Hippocrates listed the treatment for ulcers as “the flowers of silver alone, in the finest powder.”  However, just because it has been used occasionally in the past does not necessarily mean that it is safe by modern standards. After all, many ancient medical practices are considered barbaric and ineffective today.  To help us figure out how effective and safe colloidal silver for dogs really is, let’s first take a look at some diseases it is supposed to cure.

Colloidal Silver Ear Infection Dog

Colloidal silver for dogs is claimed to cure a number of infections, including ear infections.  In fact, some state that it can cure nearly every type of bacterial, fungal, and viral infection.  Colloidal silver is said to accomplish this feat due to its very small size. Because it is so small, some think that it can penetrate cells and destroy them.

Many dog owners have taken this a step further and began to use colloidal silver for their dog’s ears. It’s said to have antibacterial properties and is a liquid, so it must be great for treating ear infections, right? Not exactly. There is actually no scientific evidence that backs up the claim that colloidal silver for dogs can treat an ear infection.

It is true that colloidal silver can destroy cells.  However, it can destroy ALL cells, including your pup’s healthy ones. It is not a targeted treatment like modern medication.  Furthermore, most colloidal silver is at such a low concentration that there really isn’t going to be much cell destruction to begin with.  Due to this, it is generally considered a very ineffective treatment.

Colloidal Silver Dog Yeast Infection

A yeast infection is a fungal, inflammatory skin condition in dogs.  They are actually pretty common, especially in hot, humid environments.  Because of silver’s proclaimed anti-fungal properties, some dog owners have begun using colloidal silver for dogs to treat yeast infections in their furry friends.  However, is there actually any evidence to back up this claim?

Simply put – no. There is no scientific evidence to back up colloidal silver for dogs being an effective treatment for yeast infections.  Colloidal silver might help in a very minor manner.  However, the pure lack of scientific research in this area means that it is just as likely to hurt as it is to help.  Plus, there are many more effective modern treatments for yeast infections.

Colloidal Silver Dog Skin Allergies

Colloidal silver for dogs has also been proclaimed to be able to fend off skin allergies and excessive itchiness.  More often than not, this treatment often comes in the form of colloidal silver spray for dogs.  It is advertised that if you simply spray it on your dog, they will cease itching and their dry skin will improve.  However, there is no scientific evidence that this is true, nor do vets routinely use colloidal silver for dog skin allergies.

On top of this, even if colloidal silver improves your pet’s skin condition, serious skin conditions can point towards an underlying health problem. Self-treating your pooch at home could cause a possible underlying problem to go undiagnosed, which can cause even more issues. Because of this, it is always important to take your canine to the vet if they begin exhibiting strange behaviors or symptoms.  Self-treating at home is almost never the answer.

Is Colloidal Silver Safe for Dogs?

Many of those who advocate for use of colloidal silver for dogs claim that it is used in humans, and therefore must be safe for use in our pets too.  However, this is simply not how things work.  Just because something is safe and effective in humans does not automatically make it safe for our dogs, too.  Dogs simply react differently to certain substances than we do. They need different medicines than we do.

Furthermore, the use of silver as a medical agent is actually being phased out in many human treatments.  Study after study has shown that silver often times does more harm than good.  One study, for example, explored the effects of silver in the wound-healing process of humans.

While silver does have antibiotic properties that can prevent infections, this study found that the silver

“compound delays the wound-healing process and that silver may have serious cytotoxic activity on various host cells.” 

In other words, silver as a wound treatment actually does just as much harm as good.  It prevents infection, yes, but it also causes healing to take longer and can damage health cells.  There have been few studies done on the effects of silver on dogs specifically.  However, those that have been done have not been very promising.

More Evidence

One study discovered that orally-administered colloidal silver for dogs can cause weight loss, hypoactivity, altered liver enzymes.  Even altered blood values, enlarged hearts, and death. 

Another study involved the injection of colloidal silver into the bone marrow of dogs.  The colloidal silver did not have any specific effect on the bone marrow.  However, it did cause anorexia, weakness, weight loss, anemia, and death.  If the injection was given more than once, it caused enlargement of the bone marrow and eventually other organs.  This same study also found that if given in too high an amount, colloidal silver would cause death within 12 hours.

To sum it all up, in every study involving colloidal silver and dogs, severe side effects were discovered. In other words, it is not usually considered a safe option for your pooch.

Colloidal Silver Benefits for Dogs

As previously stated, there has not been extensive research involving the use of colloidal silver for dogs.  However, out of the scant research we do have, none of it points towards any likely health benefits for your pooch.  In fact, most of the evidence points towards it being far more harmful than good.

Before colloidal silver can be considered appropriate for dogs, there needs to be more studies and research performed.  This is especially true when it comes to treating sick dogs, who might be more prone to experiencing the negative effects of colloidal silver.  There is simply not enough research out there to make a firm conclusion!

At the end of the day, there really just hasn’t been enough research to prove whether colloidal silver is definitely safe or unsafe for your furry friend. There is just no scientific evidence supporting the various uses commonly promoted.  The studies we do have all show enormously negative effects, including things such as organ enlargement and death.

It just really isn’t worth risking your pet’s life by attempting to treat him or her at home with colloidal silver. If your pet starts acting strange or exhibiting signs that they are sick, your best bet is always to take them to the vet and get them checked out.

  1. I was wondering if dogs with bacterial infections could use chelated silver gel for there infections. Thank you she has had these infections on and off for approx. 7 yrs. For some reason this been the worst in 4 years. We live in Florida and in the winter (as now) its in the 70’s to 80’s.

  2. I used Colloidal silver for my 11 year olds bladder infection, to be given in her food, causing her to have 4 seizures 12 hours apart. She is unable to take antibiotics and thought this natural product would be safe.

  3. I was given silver dressings for a wound after an operation by the hospital worked very well also cleared a nasty ear infection in one of my dogs I’d say it’s good stuff and if hospitals use it how can you say there is no scientific evidence think you need to look into it more before making a statement on the Internet

  4. Saying that there is no scientific evidence that a substance works is a far cry from saying that it doesn’t work. Colloidal silver isn’t patentable, so no company will spend money running expensive research trials. People who use colloidal silver in appropriate dosages and strength know what results to expect.

  5. I have used colloidal silver on my schnauzers for several years. I has cleared up skin issues, ear problems. I would not be without it.

  6. Hello.
    Please advise on using Colidial silver for my bulldogs chronic ear infections (yeast). Nothing has worked (tried apoquel, allergy shots, optic solutions/cream, ear packs, ear cleanser etc). Would give it orally? Put directly in ear ? HELP..!

  7. I’ve had good results using colloidal silver. The author of this article obviously has a Big Pharma bias.

  8. I put colloidal silver in my dogs water (not a lot) after he gets a tick or has exposure to other bacterial or viral junk to help fend off illness. He is 12 and never had to take antibiotics for any issue. He gets no frontline etc. He walks 4 miles a day and exposure to wooded areas.

  9. My chihuahua was getting skin tags, I used colonial silver on the tags and they disappeared! They had been there for a long time before a tried it. Great stuff

    • My chi-poo also has these growths. She weighs 7 lbs. How much does your baby weigh and how much do you put on? Do you need to cover it. Thanks so much for replying.

  10. I have used colloidal silver on both of my Italian Greyhounds pets over the past couple of years for a number of issues and have only seen great results.
    Dental, the colloidal silver tends to soften the tarter and allow it to come off of the teeth easier when eating dry dog food or teeth brushing.
    Arthritis, using colloidal silver when arthritis flairs up in our pet, seems to reduce the discomfort and get back to normal in a few days.
    Anal gland, using colloidal silver when glands are getting full or are full seems to allow my pets to express the glands on their own without having to take to the vet for expressing the glands.
