人类吃的食物都能喂给狗狗吗？有些健康食品对人的身体有好处，对汪星人来说却是致命毒药，例如牛油果、大蒜、坚果等。《每日电讯报》列出了12种不能当狗粮的常见食物，狗主人们一定要牢记！
牛油果（Avocado）
These fleshy green fruits contain a fungicidal toxin called persin which could give your dog a digestive upset. However, it’s the large avocado stone that presents most danger because it could potentially block the gastrointestinal tract, leaving your dog requiring surgery.
这些绿色肉质水果含有一种名为persin的杀菌毒素，会导致狗狗消化不良。不过，牛油果最危险的是其巨大的果核，它可能阻塞狗狗的胃肠道，需要通过手术取出。
骨头（Bones）
Contrary to popular opinion, bones are bad for dogs. Not only can they potentially choke your dog, they can cause blockages in the gut, intestinal damage and chipped or broken teeth.
与多数人的观点相反，骨头其实对狗狗有害。骨头不仅可能会让狗狗窒息，还可能导致肠道阻塞、肠道损伤和牙齿碎裂。
生面团（Bread dough）
The smell of unbaked yeasty bread dough could attract your dog’s attention but it should always be kept out of reach. If eaten, the dough could expand dangerously in your dog’s stomach, and the fermented yeast could become toxic.
未烘焙的发酵面团的气味能吸引狗狗的注意力，但要始终确保不要让狗狗接触面团。如果面团被狗狗吃下，可能会在胃中膨胀，这十分危险，而且发酵的酵母也有毒性。
巧克力（Chocolate）
Chocolate and cocoa-based products contain a stimulating substance called theobromine which is extremely poisonous to dogs – the darker the chocolate, the greater the risk. Even a few ounces of chocolate could leave your dog with sickness, diarrhoea, dehydration, and high blood pressure, and the effect is potentially worse in small breeds. If your dog appears restless or agitated and you think chocolate poisoning could be the cause, contact your vet.
巧克力和可可类食物含有可可碱，这种刺激性物质对狗狗有剧毒。巧克力越纯，危害越大。即使只有几盎司的巧克力，也会让狗狗出现呕吐、腹泻、脱水和高血压症状，而小型犬的症状可能更糟糕。如果你发现家里的汪星人突然焦躁不安，而你猜测这可能是巧克力中毒引起的，那就联系你的兽医。
咖啡因（Caffeine）
Any product with caffeine can have a similar effect on your dog to chocolate and could ultimately damage its heart. So, keep your coffee, teabags and fizzy drinks well away from inquisitive tongues.
不仅是巧克力，任何含咖啡因的食品都会对狗狗造成类似的伤害，最终还可能损害它们的心脏。所以，确保狗狗好奇的舌头远离你的咖啡、茶包和碳酸饮料。
乳制品（Dairy products）
Many dogs find it difficult to digest the lactose in milk, butter and cheese because they don’t produce enough of the enzyme, lactase. The effects can range from a mild tummy upset to an irritating skin allergy.
许多狗难以消化牛奶、黄油和奶酪中的乳糖，因为它们体内不能产生足够的乳糖分解酶。乳糖不耐受的症状可以表现为轻微腹泻、引起瘙痒的皮肤过敏。
果脯（Dried fruit）
Raisins, currants and sultanas affect different dogs in different ways and scientists can’t work out why. However, experts agree that they contain chemical compounds that are potentially very toxic to dogs. At best, your dog could suffer from diarrhoea and vomiting and, at worst, dried-fruit poisoning could lead to kidney failure.
葡萄干、醋栗和无核小葡萄干对不同狗狗的影响不同，科学家无法弄清其中原因。但专家认为，这些果脯包含可能对狗狗有剧毒的化学物质。果脯中毒最轻可引起腹泻和呕吐，而最重可导致肾衰竭。
鲜果（Fresh fruit）
Like dried fruit, grapes are highly toxic and should be kept away from your pet. The pips and stones of some fruits (such as apples, plums, peaches and cherries) contain a chemical called amygdalin, which can cause a digestive upset. Large fruit stones are also a choking hazard – particularly among puppies and small breeds.
像果脯一样，葡萄毒性很大，应该让你的宠物远离。苹果、李子、桃子和樱桃等水果的种子和果核含有一种叫做苦杏苷的化学物质。这种化学物质会引起消化不良。大型果核还有窒息的危险，尤其是对于小狗崽和小型犬。
大蒜和洋葱（Garlic and onion）
Members of the allium family (including garlic, leeks and onions) contain a substance called organosulfides which could affect your dog’s red blood cells – too much garlic or onion (either raw or cooked) could ultimately lead to anaemia. The symptoms take a few days to appear so if your dog appears sleepy and lethargic, head straight to your vet.
大蒜、韭菜、洋葱等葱属植物含有一种有机硫化物，可能破坏狗狗的血红细胞——摄入过量大蒜或洋葱（生或熟）会导致贫血。但症状需要几天才会出现，所以如果你的汪星人突然出现困倦和嗜睡的情况，直接去看兽医吧！
坚果（Nuts）
Nuts are high in fat and should be avoided by dogs but the most toxic of all are macadamia nuts. They can cause vomiting, increased temperature, tremors and a rapid heart beat.
坚果的脂肪含量很高，不应该给狗狗吃。而毒性最大的坚果是夏威夷果。夏威夷果能导致呕吐、体温升高、颤抖和心跳加快。
木糖醇（Xylitol）
This artificial sweetener is used in sweets, cakes, toothpaste and chewing gum and has a laxative effect on humans. For dogs, though, an excess of xylitol could prove fatal because it kickstarts a rapid release of the hormone insulin. Too much insulin affects the amount of glucose (sugar) in your dog’s blood which, in turn, could cause seizures and affect your pet’s liver. The symptoms of xylitol poisoning include weakness, vomiting and a lack of co-ordination, and it requires urgent veterinary attention.
这种人造甜味剂用于糖果、糕点、牙膏和口香糖中，对人体有通便作用。然而，对狗来说，摄入过量木糖醇可能会致命，因为木糖醇可以导致胰岛素迅速分泌。胰岛素过量会影响狗狗血液中的葡萄糖含量，结果可能会引发癫痫，损伤狗狗的肝脏。木糖醇中毒的症状包括身体虚弱，呕吐和四肢不协调，一旦中毒需要立即找兽医治疗。
