Some neat ideas over on the I Love Dogs site which could help keep your dogs safe.
Particularly like the Pet Alert Sticker (although the obvious down side is that it alert would be dog thieves to the fact that you have a dog at home), the ‘My Pet Is At Home’ wallet cards and key fobs, and I am pretty sure most fridges would benefit from a reminder of what foods are toxic for dogs.
well worth taking a look here and remember that every purchase helps feed a shelter dog!
