I have never known a time when there has not been a dog in my life. Right from being a tiny child myself to the grandmother of one now, there has always been a four legged friend around. I really can't imagine living without one. Our house is a home. A proper home has a dog ( or two or three) in it 
My dogs greet me every morning bursting with so much love and affection, tails wagging and bodies wriggling, they make me smile even when don't feel like it.
If I'm sad one of them will come for a cuddle. When I was a little girl the dog in our house was always my best friend. I would share my sweets with him and if I was crying he always came and sat with me.
They are your friend, your confessor, your comfort. They bring joy to your heart, and they break it when they die. They seem to know when you are sad, and when you are happy they add to the fun.
Walking the dog gets you out of the house, and you meet other doggie owners who are equally as besotted and daft. Dogs make people smile, they bring us together in a way nobody else can ..that is through laughter.
And anyway, who needs a man when you have a dog ?
