1 00:00:00,520 --> 00:00:03,840 Speaker 1: Welcome to Brainstuff from house stuff Works dot com where 2 00:00:03,840 --> 00:00:15,400 Speaker 1: smart happens. Hi Am Marshall Brain with today's question, is 3 00:00:15,680 --> 00:00:20,200 Speaker 1: chocolate poisonous to dogs? You may have heard people say 4 00:00:20,239 --> 00:00:24,320 Speaker 1: that chocolate will kill dogs? Does that make sense? If 5 00:00:24,360 --> 00:00:28,040 Speaker 1: I can eat chocolate, why can't my dog? It turns 6 00:00:28,080 --> 00:00:31,520 Speaker 1: out that for dogs, a chemical and chocolate called theo 7 00:00:31,600 --> 00:00:35,600 Speaker 1: bromine is the source of the problem. Theobromine is similar 8 00:00:35,600 --> 00:00:40,159 Speaker 1: to caffeine. It's toxic to dogs when it ingests between 9 00:00:40,159 --> 00:00:44,440 Speaker 1: a hundred and a hundred and fifty milligrams per kilogram 10 00:00:44,680 --> 00:00:49,280 Speaker 1: of body weight. Different types of chocolate contain different amounts 11 00:00:49,280 --> 00:00:53,360 Speaker 1: of theobromine. It would take about twenty ounces of milk 12 00:00:53,440 --> 00:00:56,840 Speaker 1: chocolate to kill a twenty pound dog, but only two 13 00:00:56,880 --> 00:01:01,800 Speaker 1: ounces of Baker's chocolate or six ounce is of semisweet chocolate. 14 00:01:02,160 --> 00:01:04,840 Speaker 1: It's not that hard for a dog to get into 15 00:01:04,880 --> 00:01:08,480 Speaker 1: something like an Easter basket full of chocolate eggs and 16 00:01:08,600 --> 00:01:11,560 Speaker 1: chocolate bunnies and gobble up to a pound or two 17 00:01:11,640 --> 00:01:15,520 Speaker 1: of chocolate in a single sitting. If the dog is small, 18 00:01:15,560 --> 00:01:19,560 Speaker 1: that could be deadly. It turns out that chocolate poisoning 19 00:01:19,760 --> 00:01:23,280 Speaker 1: is actually not as unusual as it sounds for a 20 00:01:23,400 --> 00:01:27,559 Speaker 1: human being. Caffeine is toxic at levels of fifty milligrams 21 00:01:27,560 --> 00:01:30,440 Speaker 1: per kilogram of body weight. That's the same as for 22 00:01:30,640 --> 00:01:35,720 Speaker 1: dogs with theobromine. Humans generally weigh a lot more than dogs, 23 00:01:35,720 --> 00:01:39,120 Speaker 1: but small children can get into trouble with caffeine or 24 00:01:39,240 --> 00:01:42,720 Speaker 1: chocolate if they consume too much of it. Infants are 25 00:01:42,840 --> 00:01:47,240 Speaker 1: especially vulnerable because they don't eliminate caffeine from the bloodstream 26 00:01:47,319 --> 00:01:51,320 Speaker 1: nearly as quickly as adults do. Dogs have this strange 27 00:01:51,320 --> 00:01:55,280 Speaker 1: ability to wolf down lots more food than a human does, 28 00:01:55,600 --> 00:01:58,080 Speaker 1: and that makes a dog a lot more susceptible than 29 00:01:58,200 --> 00:02:02,880 Speaker 1: chocolate poisoning than a human it be be sure to 30 00:02:02,960 --> 00:02:05,720 Speaker 1: check out our new video podcast, Stuff from the Future. 31 00:02:06,080 --> 00:02:08,399 Speaker 1: Join how staf Work staff as we explore the most 32 00:02:08,400 --> 00:02:13,480 Speaker 1: promising and perplexing possibilities of tomorrow.
