The SPF of a dog lick

I have a dog.

My dog licks me.

He likes to lick the top of my head when we are sitting on the outside swing. Go figure.

It occurred to me that a dog lick (nice way to say dog spit) might have some SPF value. I googled the subject and there evidently has not been any research done on this subject.

There could be some grant money laying around for this. Never know. The government funds stranger research studies.

I can report, anecdotaly, that since Danny has been licking my head when we are out in the sun, I have not had a sunburn on my mainly bald head.

I do live in Oregon though.

That might have something to do with the lack of sunburn.

I used to live in southern California. I often got sunburns.

I would rather have dog spit on my head than move back to "Sunny Southern California"!!!
