Both goats and cows are domesticated animals. This means that they have provided food and have worked for humans for thousands of years. However, goats are much smaller than cows. A goat is about one-sixth the size of a cow, which means it is easier to move from place to place and to handle. Both goats and cows produce milk that humans can drink. But dairy goats have a longer productive life than cows. They are productive for 8-10 years, as opposed to cows, which have 4-6 years of productive life.
