Dogs use their innate instincts to find their own sleeping spots in the home. Some owners may wonder why their dogs sleep in one place in the winter and another place in the summer. Dogs will choose different locations for their nests in different seasons and weather conditions. When the weather is cold, dogs will choose a corner that is sheltered from the wind at night and sunny in the morning. When the weather is hot, dogs will choose a ventilated, dry, and cool place to sleep.
