Never had nor wanted kids....always preferred dogs of which we have 9 now (Chihuahua all the way up to a Great Pyrenees), with the exception of two of them they were all abandoned or given to us as a the stop right before the pound. Just took two of them backpacking with me in Wyoming as well where they performed fantastically.
In most instances I prefer my dogs companionship to any humans except my wife and the only time they sleep out side is when they are backpacking with me or its really cold and they want to be there (Malamute & Husky).
I wouldn't take them to a park where they interfere with kids on the things kids play in or on though......especially the water pads. most dog owners I know though are pretty responsible and wouldn't do that either.
One of my favorite explanations about our four-legged friends;
"And the dog heard"
God summoned a beast from the field and he said, "Behold man, created in my image. Therefore, adore him. You shall protect him in the wilderness, shepherd his flocks, watch over his children, accompany him wherever he may go...even into civilization. You shall be his companion, his ally, his slave."
"To do these things," God said, "I endow you with these instincts, uncommon to other beasts: Faithfulness, devotion and understanding surpassing those of man himself."
"Lest it impair your courage, you shall never foresee your death. Lest it impair your loyalty, you shall be blind to the faults of man. Lest it impair your understanding, you are denied the power of words."
"Let no fault of language cleave an accord beyond that of man with any other beast or even man with man. Speak to you master only with your mind and through your honest eyes."
"Walk by his side; sleep in his doorway; forage for him; ward off his afflictions; love him and comfort him. And in return for this, man will fulfill your needs and wants --- which shall be only food, shelter and affection."
"So be silent, and be a friend to man. Guide him through the perils along the way to this land that I have promised him. This shall be your destiny and your immortality." So spoke the Lord.
And the dog heard and was content.
