You should consider buying or making raw food diet for dogs to provide the healthiest diet for the dog. Most industrial products are full of compounds that aren't good for dogs, despite the flavor and aroma. Use quality ingredients like lean meat, grains, vegetables and fruits, but make sure the larger percent is meat.
Regardless of the kind of dog you have, hang-up a number of ‘beware of dogs’ signs on your home. They're known to be deterrents to criminals and may help protect you home from attacks. That signal alone suggests probable inability of any robbery attempt. The barks can also keep them away.
