Not 100% sure what you're asking here. It's not dangerous to breed a spider? lol
If you're talking about the spider wobble, that only affects spiders--it's part of the spider gene, there is no evidence that a separate gene is involved at all. So only spiders will have the spider wobble issue. Most of them have it to some noticeable degree, and there is strong reason to believe that even those that don't still have the potential (their spider offspring will probably wobble too).
Since it is part of the spider gene, it doesn't affect any animal without the spider gene.
There are a few cases of snakes other than spiders showing neurological problems, but no evidence that's related to the spider wobble.
