Dog = 狗 [gǒu]
A man walks his dog on a long leash, but five balloons hold the dog up in the air like a kite. Still a 狗.
狗 (gǒu) means “dog.” A puppy is 小狗 (xiǎo gǒu). Count dogs with 只 (zhī) or 条 (tiáo): 一只狗, one dog.
To walk a dog is 遛狗 (liù gǒu).
他每天晚上遛狗。 — Tā měitiān wǎnshang liù gǒu. — He walks the dog every evening.
你喜欢狗还是猫？ — Nǐ xǐhuan gǒu háishi māo? — Do you like dogs or cats?
