Giant dog breed - online puzzles

A giant dog breed has no universal height or weight classification, although some groups define " giant breeds" as those heavier than 45.4 kilograms (100 lb) in males and at least 45.4 kilograms (100 lb) in females. Giant breeds grow rapidly, but take longer to mature into their full adult sizes than smaller dogs not reaching full height until 18 months and not reaching full weight until their second birthday.
