熊 (kuma) is the Japanese word for "bear" and we can attach 子 (ko) to indicate "child", thus 子熊 (kokuma) would mean "child bear" or "cub". Other instances where this is done is with puppy (子犬, koinu) and kitten (子猫, koneko).
Born as in "was born"? 生まれた (umareta) u-ma-re-ta
To say "I like puppies" would be 私は すきな 子犬 だす. This is pronounced "watashi WA suki na koinu des." [edit] This made me laugh. "Watashi WA suki na koinu desu" translates to "I am a beloved puppy." The correct way to say it is "Watashi WA koinu GA suki desu" "私 は 子犬 が 好き です。" Verified my choice with Google translate.
