Dogs have live births, usually in litters of around six puppies. They are mammals, so in addition to giving live birth, they have fur and produce milk for the babies. How long a dog lives varies by breed, but most dogs live 12 to 14 years. A puppy is considered an adult dog at the age of about one year.
For some math fun: Some people say that one human year is equal to 7 dog years. They say this because dogs become adults when they are between one and two years old.
If you are eight years old, how old is that in dog years? (Hint: Multiply 8 by 7). Find out what your age equals in dog years!
