Dogs come in all sizes and shapes, from tiny Chihuahuas to massive Great Danes. If you love big dogs, you have many large breeds to choose from that feature a range of personalities and coat types. Before adopting one of these large breeds, take into consideration your space requirements; some large breeds can thrive living in smaller spaces while others require larger homes with yards for proper care. Furthermore, large dog breeds typically cost more than smaller breeds in terms of food costs, medications costs, grooming needs as well as supplies.
