I use colloidal silver in my dogs fresh water or in their daily meal with water added to the kibble.
It is used topically as well for skin irritations.
This is a good article listing the benefits for dogs:
And here is another:
Not all colloidal silver products are created equal.
This is a great article to learn the difference when buying a quality product for your dog.
I also read of someone that saved an adult dog from Parvo by using colloidal silver orally.
You can also use CS in dogs’ ears for infections. Use an eye dropper and drop it in the ear, when needed, and then gentle massage up and down to get it in the ear canal. This product was recommended by a friend:
it’s safe for pets, says so on the bottle.
Apply 2X daily in each ear for 5 to 7 days.
Then clean the ears as needed
As always, I am not a vet, just passing on useful holistic info.
It is always best to discuss these products with your vet, or better yet, a holistic vet.
Hope this helps some of you with your dogs health.
