No matter what kind of dog you may have, hang up a few "Beware of Dog" signs on your property. They are known deterrents to would-be burglars and can help protect you and your family. Just the sign alone indicates probable failure of any robbery attempt and a single bark will have them running away!
Give your dog a great place to sleep. Every dog needs a bed to call his own that is temperature controlled and comfortable. If not, the dog may alternate sleeping locations between undesirable locations, such as your sofa when you're not watching. A bed also gives him a great sense of security and belonging.
In the past, most people used dogs to help them hunt or herd. Now, the relationship between humans and dogs is very different. However, that doesn't mean the past no longer applies. There's a wealth of dog care knowledge out there, and if you use it, you'll be much better off.
