11. Great Dane
Great Danes are gentle giants that weigh in at 110 to 175 pounds and cost $600 to $1,500. Owning one can eat up time since they’re social creatures that need a lot of your attention.
They’re docile and good-natured, but their sheer bulk means you’ll have to spend a lot on bedding and a larger than a normal crate. To accommodate their size and appetite, they need high-quality food specially formulated for a large breed that can cost $1,800 per year.
