Slug beer traps work really well, as do half grapefruits dotted around the place. You can buy animal friendly slug/snail repellents which I use occasionally - they work quite well. Just be careful that your dogs don't get a chance to eat slugs - they have a parasite called heartworm which can kill.
The only thing necessary for the triumph of evil is for good men to do nothing.
