Can Colloidal Silver Cause Cancer in Dogs?

Absolutely. We have absolutely no idea if colloidal silver can cause cancer in dogs, especially when taken orally. So it’s just as likely that it can. And under no circumstances does the kidney or liver appreciate metabolizing metals.

But maybe colloidal silver kills germs. And here’s why I think that could contribute to carcinogenesis:

Colloidal silver has properties to kill germs. Practically ALL germs. Unselectively. But Science has learned that there are Good and Bad germs in the biological / tissue environment. It’s theorized that there are even “police germs” that kill other germs in the skin, internal organs and elsewhere.

But someone noticed that Colloidal Silver could kill germs, and decided we should eat it. Nobody died – and so it must be good.

The reason they think colloidal silver kills germs is because THIS stuff actually does kill germs. Very well. In fact Silver Sulfadiazine Cream kills germs so well, and so safely, that it’s used on third degree burns to keep them sterile during healing. And it has the word Silver in it. So it must be the same thing as colloidal silver. I have to check with my Facebook Group.

So if this Ascend silver sulfadiazine kills germs and contains silver and is good: Then because, according to the leading lay-theorists in Facebook Groups, colloidal silver is ‘the same thing’ and kills germs, and must be good.

Except it’s a metal.

Now I see colloidal silver being sprayed in dogs mouths and put in their water as if sterilizing their guts is a Good Thing.

And if taken internally has the potential to create similar problems that practically ALL metals taken internally do. Either by improper storage in the liver, killing cells and germs that are essential for our success, or just creating cancer-favorable conditions via the immune suppression caused by retention of most heavy metals. No one knows.

Do we know if this is true? NO.

What we ALSO don’t know is, if ANY of the various internal uses for Colloidal Silver (besides topical) are safe.

We always shove “fad items” into everything we ingest, apply and wear…

  • I saw a shampoo that was “Gluten Free”
  • I saw shampoos that provided vitamins to your hair.
  • I saw a shampoo that provided Echinacea for your hair when Echinacea was the fad-cure-all ten years ago.

Now I see colloidal silver being sprayed in dogs mouths and put in their water as if sterilizing their guts is a Good Thing. And storing / excreting silver is as easy (or as hard) as metabolizing copper. People don’t know. So in the meantime let’s keep silver OUT of the dog’s liver and kidneys.

Just sayin’.
