Do dogs have tastebuds

Yes they do, but in their stomachs, not their mouths. Dogs eat something because it smells yummy, if when it gets to their stomachs they then decide that it tastes foul they'll throw it back up again.

狗确实有味蕾，可以像人类一样品尝食物。狗的味蕾主要集中在它们的舌头的不同部位，能够识别的味道包括甜、咸、酸和苦。虽然狗的味觉不如人类灵敏，但它们对食物的气味和味道仍然有一定的辨别能力。
