skin spray for humans is 10 drops MMS activated, in 1 oz of water. That should be safe for your furkiddo, even applied with a cloth pad. We've got some people here with quite a bit of experience with their animals, I hope they'll contribute.
JH, in his latest book says in the chapter on healing animals:
Using MMS 1 on the Skin
There are thousands of different kinds of rashes, cancers, sores,
and diseases of the skin that MMS1 and 2 can overcome in two or
three days to a week. I always use a much stronger MMS1 spray for
the skin than for the mouth.
• Use 10 drops of MMS1 per ounce of water and the appropriate
amount of citric acid activator in a 4 ounce spray bottle.
Chapter 12 gives more details on how to make an MMS1
dose. Be sure the 10 drops of MMS1 are activated.
But two ounces isn’t much. My suggestion for an animal spray
bottle would be a one-quart bottle at least, or 1000 ml. In an empty
one-quart bottle, put 4 teaspoons of MMS1. That would be 80 drops
per teaspoon or 320 drops of MMS1 for a quart bottle or 1000 ml.
Then add the same amount of 50% citric acid, or 5 times that amount
of 10% citric acid. Wait the 20 seconds or the 3 minutes and fill the
bottle with water. That will last about 5 days.
Now that you have that spray, you can spray all the sores and
rashes, and diseases that your animals have anywhere on the skin
or face. Once a day might not be enough. Some diseases require
spray on the skin, but also taking by mouth. Most skin problems
require that you spray three or four times a day, sometimes hourly.
Anytime an animal is wounded, spray directly into the wound. Do
that for yourself as well.
• MMS1 or MMS2 applied to an open wound will help coagulate
the blood and stop the bleeding and totally prevent infection.
The only issue is that MMS may not kill the mites - it won't kill fleas
JH says:
Chlorine dioxide as used with humans and animals kills pathogens but cannot
kill fleas and other bugs because it is not strong enough. It is a weak
oxidizer. You can spray into the ears with the full strength skin spray
as given above. It kills parasites but only micro-size parasite. I don’t
know what size parasites it will kill. It kills all parasite diseases, but
large tick-size parasites will probably not be affected.
