If you don't own a dog, at least one, there is not necessarily anything wrong with you, but there may be something wrong with your life.
Dogs feel very strongly that they should always go with you in the car, in case the need should arise for them to bark violently at nothing right in your ear.
A dog reflects the family life. Whoever saw a frisky dog in a gloomy family, or a sad dog in a happy one? Snarling people have snarling dogs, dangerous people have dangerous ones.
It's just the most amazing thing to love a dog, isn't it? It makes our relationships with people seem as boring as a bowl of oatmeal.
