We already know that in Greek, dog is σκύλος (skýlos) and cat is γάτα (gáta).
Now let's learn about some farm animals!
cow - αγελάδα (ageláda) - sounds like ah-gay-LAH-dah
chicken - κοτόπουλο (kotópoulo) - sounds like koh-TOH-poh-oo-loh
pig - χοίρο (choíro) - sounds like xh-EE-doh
Also in Greek cows say mou mou, chickens say ko ko ko, and pigs say greelizee!
