With other animals is ok...
I have a 'clean room' of sorts that I don't let dogs into, nor do i let the dogs into the rat shed. My dogs spend some time outside I always worry what they could bring in, be it fleas into the rat shed, or mite larvae into the reptile room. My vet recommended this a long time ago, but I have never actually had a problem to spark true concern, so this is all off recommendations, not bad experience. Also I have known a few people to really let the dogs go rampant in rooms with better collections than my own. If you have dogs that spend a decent amount of time outside in the woods, you may want to consider moving the ball, but if you have indoor dogs, listen to the rest of the posts above me
