Mongrels
Mongrels can be the best of friends. They are often more original and enterprising than their too highly-bred cousins, and they are very self-reliant; but as a rule they are not so courageous nor so steadfast as a well-bred dog. The chief advantage of possessing a mongrel is that dog-stealers are less likely to be tempted by him, and you can give him more freedom, which will make him more interesting and intelligent than a dog you need to shut up and look after carefully.
