I do and, I don't.
Love my dog but no way I would find that acceptable. The animal hair thing got to be a big deal for me a few yrs. back (yrs before rec. was legal).
I was helping to supply another WA MMJ patient who had sever allergies to animal hair and ANY hair in the MMJ just wasn't acceptable.
Poor guy had one hell of a time finding anybody growing that could guarantee him no animal hairs... but at the time, the only pet I had was a Beardy Dragon so he came to me about it. Nice guy and I was able to help him out until he was able to set himself up properly.
Shouldn't really be that hard to do but all you should really need is an incoming air source that comes from outside the home and a secure room.
I suppose it's a matter of priority but if you're one that doesn't really care... at least let those you share with, know what they are getting.
If someone with a nasty allergy gets a hold of that stuff... it could go badly for them.
