You can even handle them. The only thing to wory about are those two big glands behind their eyes. If you squeeze them hard enough of if they are stressed out enough they will ooze or shoot out a white puss looking from them.

The only real issue I can see if your dog trying to pick one up in his or her mouth and getting the toxin into it's system. Your best bet is just to keep an eye on the dog when it's outside since it's very possible if it ingests enough to get sick or even die. The toxin is pretty strong stuff and kills plenty of native fauna in Austrailia due to animals like lizards, snakes and crocs eating them.

If you have any light sources on outside during the night I'd turn them off. This might detour them from hunting in the area as light attracts bugs and often they'll sit below a light source and eat what drops to the ground. Also removing any standing pools of water, even if it be low lying empty pots and filling in pot holes that fill up during rain storms will help.
