One main reason for getting a dog bed is a dog’s explicit wish for having his own place. You can even call that a wish for privacy. It’s true. As much as dogs love your company and attention, they also need their calm moments, a place where they can retreat and find peace.
Another important reason speaking for a dog bed is the hygiene factor. A dog is never as clean as humans are, and I don’t just speak about their hair all over your place.
