My 6 month old english setter was near dead with parvo virus when I took him to the vet. The vet wanted to put him in isolation and give him IV's and try to save him. (I knew I would spend hundrends of dollars at the vet and he would probably still die. So I told her that I was a nurse, just teach me what to do. I learned how to put IV fluids under his skin (he looked like a camel) and I gave him his Colloidal Silver by mouth. I syringed it into his mouth and he could hardly swallow. I gave him a ounce every hour on the hour.
The doctor told me she thought he would be dead by morning.
Well, within a day he was like a new dog. He started drinking water with a pinch of Sea Salt and Sugar to replace electrolytes. I fed him chicken soup with lots of veggies.
I must say that he survived and is thriving now. We were buddies before, but when you look into your dying dogs eyes and help him to survive with your care, it really bonds you even more than before.
