??why do dogs bury bones?
狗狗为啥喜爱埋骨头?
chewing bones is a favorite pastime of dogs. if a bone is very beloved, the dog might even bury it.?to humans, this behavior may seem odd, so why do dogs invest so much energy in burying their prized possessions?
啃骨头是狗狗最喜爱的文娱方法。狗狗甚至会把特别心爱的骨头埋起来。对人类来说，这种行为如同很新鲜，那么狗狗为啥会花那么多的精利巴它们心爱的物品埋起来呢？
“the reason why a dog buries something is to save it for later,” says teoti anderson, professional dog trainer and behavior consultant based in florida. “when you don’t know when you’ll find your next meal, it makes sense to hide?leftovers.”
佛罗里达州的专业训狗师和动物行为参谋特奥蒂·安德森标明：“狗狗之所以把东西埋起来是为了藏着日后运用，当你不晓得啥时分能吃到下一顿饭时，将剩菜储存是有意义的。”
the act of burying bones is a type of “food caching,” that is, storing available food supplies for the purpose of later access. it’s a common behavior in many species of birds and mammals, including in the canine ancestors of domestic dogs —?gray wolves?— which is where dogs inherited their burying instincts.?
埋骨头的行为也是一种“食物贮藏”方法（即储存可用的食物供今后食用）。这是许多鸟类和哺乳动物（包括家犬的祖先灰狼，狗狗
正是继承了它们埋葬食物的天性）的广泛行为。
while wolves, which are known for their?cunning?hunting skills, tend to stay in a?scavenge?area long enough to devour their prey entirely, they will occasionally carry and bury the remains of a kill, according to a 1976 study published in the journal?ethology. (wolves and other canids are known as “scatter hoarders,” meaning they stash their leftover food in hideaways located over fairly large areas.)?
1976年宣告在《动物行为学》期刊上的一项研讨闪现，狼以其奸刁的捕猎技能而出名，它们一般会在食腐区待上满足长的时刻，将猎物完全吃掉，但偶尔也会带着并埋葬猎物的遗骸。(狼和其他犬科动物被称为“涣散囤积者”，意思是它们把剩下的食物贮藏在恰当广的一片区域。)
this same study showed that even wolf pups cache, and will move their cache to keep it from being discovered by a sibling. so, when dogs exhibit this seemingly unusual behavior in your backyard, rest assured — they’re simply following their instinctual “inner wolf.”
研讨还发现，即就是狼崽也会贮藏东西，而且会移动它们的贮藏点，避免被其他同类发现。所以，当狗狗在你家后院体现出这种看似不寻常的行为时，请定心——它们只是在遵从它们天性的“狼性”。
most dogs today don’t need to store food because they have doting pet parents to feed them, but that doesn’t mean their natural urge to squirrel things away for later doesn’t still exist. sometimes, the instinct to bury things has nothing to do with storing food or protecting it from scavengers.?
如今，大大都狗狗都无需贮藏食物，因为有溺爱它们的宠物父母来喂食它们，但这并不料味着它们储存食物以备日后食用的天性激动不复存在。有时，埋藏东西的天性与贮藏食物或维护食物免受食腐动物损坏。
according to dog behaviorist cesar millan, burying can be a dog’s way of savoring?cherished objects, so they can be enjoyed again later. it can also be a way for bored dogs to initiate play with their owner, or a method of stress relief for anxious dogs.
根据狗行为学家塞萨尔·米兰的说法，埋东西可所以狗狗保存喜爱物品的一种方法，这样它们日后还能再次品尝。这也可所以无聊的狗狗与主人玩耍的一种方法，或是焦虑的狗狗减轻压力的一种办法。
dogs that do “cache” seem to visit their hoards whenever the mood hits. “some dogs stash a treat and then ignore it for a week. some dogs seem indecisive and move their prize 20 times before settling on one [spot]. and other dogs bury a bone and forget it altogether,” anderson said.?
每当心境丢失的时分，那些会“贮藏”食物的狗狗如同就会去看看它们的囤积物。安德森标明：“有些狗会把零食藏起来，然后一周都不吃。有些狗看起来优柔寡断，把它们的战利品转移了20次才究竟贮藏在一个当地。还有一些狗把骨头埋起来，然后就忘掉了。”
if a dog doesn’t retrieve a treasure, you can bet it?isn’t?because it forgot its whereabouts. dogs have an incredibly keen sense of smell, about 10,000 to 100,000 times as powerful as that of humans, according to research in the journal?applied animal behaviour science, so remembering their hideaways is rarely ever an issue.?
假定一只狗没有找回它的瑰宝，你可以打赌它必定不是忘掉了瑰宝的方位。宣告在《使用动物行为科学》期刊上的一项研讨闪现，狗的嗅觉非常敏锐，大约是人类的1万-10万倍，所以记住瑰宝的方位对它们来说历来都不是疑问。
besides bones, what types of things do dogs like to bury??it runs the?gamut. “i once knew a dog who would bury rocks. i have no idea why these rocks were so special, but they were special to him,”?anderson said.?
除了骨头，狗狗还喜爱埋啥东西呢?几乎包括了一切品种。安德森标明：“我早年知道一只会埋石头的狗狗。我看不出这些石头有啥特别之处，但这些石头对它来说很特别。”
