Small Red Insects

[DW22]

Hey, so I just introduced my pigs to the outdoors, they loved it, but when I picked them up, I could see small insects, which look red crawling on their top layer of fur. Does anyone know what these are and if they are dangerous?
I've attached an image, it won't show the actual insect, just the size of it! Thanks guys

The only small red insect I can think of is the spider mite

I would get them all cleaned up, where outside were they?

I've cleaned the visible ones, and they've groomed each other too! Just in our back garden, on the grass
