00:00:01,840 --> 00:00:07,720
Speaker 1: Welcome to brain Stuff, a production of iHeartRadio. Hey brain Stuff,

2
00:00:07,760 --> 00:00:11,080
Speaker 1: Lauren Boglebomb here with another classic episode of the podcast.

3
00:00:11,840 --> 00:00:15,880
Speaker 1: In this one, we discuss what causes the gloriously snack

4
00:00:16,079 --> 00:00:19,000
Speaker 1: like scent of a dog's pause. If you happen to

5
00:00:19,040 --> 00:00:20,959
Speaker 1: not be a fan, we won't hold it against you, though,

6
00:00:21,200 --> 00:00:25,520
Speaker 1: Just more puppy pause for the rest of us. Hey

7
00:00:25,560 --> 00:00:28,640
Speaker 1: brain Stuff. I'm Lauren vogel Bomb, and you probably don't

8
00:00:28,680 --> 00:00:31,920
Speaker 1: go around smelling dog's feet all the time, But even

9
00:00:31,960 --> 00:00:34,720
Speaker 1: if you did, or even only on occasion, the odor

10
00:00:34,840 --> 00:00:38,440
Speaker 1: might remind you of something crunchy. As it turns out,

11
00:00:38,479 --> 00:00:41,040
Speaker 1: there are many dogs of all breeds and sizes whose

12
00:00:41,080 --> 00:00:44,760
Speaker 1: feet smell like corn chips or popcorn. Some say or

13
00:00:45,000 --> 00:00:48,519
Speaker 1: not show flavored tortilla chips. Although the smell and its

14
00:00:48,560 --> 00:00:52,680
Speaker 1: interpretations vary, most people who sniff their pets odoriferous feet

15
00:00:52,880 --> 00:00:55,520
Speaker 1: are convinced their nostrils are picking up some kind of

16
00:00:55,600 --> 00:00:58,760
Speaker 1: crunchy snack. For rietal, I think the corn chip brand

17
00:00:58,800 --> 00:01:02,560
Speaker 1: Freedo's in particular. But why it has everything to do

18
00:01:02,640 --> 00:01:07,800
Speaker 1: with microorganisms. The average human body comprises thirty trillion cells

19
00:01:08,000 --> 00:01:11,280
Speaker 1: and is topped by skin covered by forty trillion bacteria.

20
00:01:11,640 --> 00:01:15,160
Speaker 1: But this ratio may be even greater for dogs. In particular,

21
00:01:15,360 --> 00:01:18,960
Speaker 1: the nooks and crannies of dog paws pick up actinobacteria

22
00:01:19,000 --> 00:01:22,920
Speaker 1: from soil, where the bacteria lives and multiplies. Most of

23
00:01:22,959 --> 00:01:26,200
Speaker 1: a dog's apacrene glands or sweat glands, are concentrated in

24
00:01:26,240 --> 00:01:29,240
Speaker 1: the pads on their feet. These pads are surrounded by

25
00:01:29,280 --> 00:01:32,080
Speaker 1: fur and create damp and warm crevices that become an

26
00:01:32,120 --> 00:01:35,520
Speaker 1: excellent breeding ground for all kinds of bacterial growth. With

27
00:01:35,600 --> 00:01:39,080
Speaker 1: all this reproduction comes a number of accompanying smells, most

28
00:01:39,080 --> 00:01:42,399
Speaker 1: of which are related to yeast and bacterial byproducts. You know,

29
00:01:42,640 --> 00:01:46,640
Speaker 1: microorganism poop. Yeast and bacterial poop is responsible for a

30
00:01:46,680 --> 00:01:49,680
Speaker 1: lot of the sense we encounter, from unpleasant body odor

31
00:01:49,720 --> 00:01:53,160
Speaker 1: to the attractive smells in wine, bread, and cheese. So

32
00:01:53,720 --> 00:01:57,760
Speaker 1: which bacteria cause your dog's feet to smell like a snack? Yeast?

33
00:01:57,800 --> 00:02:01,200
Speaker 1: For one, Yeast loves to thrive in warm, wet environments,

34
00:02:01,480 --> 00:02:04,960
Speaker 1: and so do bacteria called pseudomonis, which emit an odor

35
00:02:04,960 --> 00:02:08,600
Speaker 1: that many people interpret as popcorn. The real culprit in

36
00:02:08,600 --> 00:02:11,920
Speaker 1: that corn chip smell, though, are proteus bacteria, which emit

37
00:02:11,960 --> 00:02:15,160
Speaker 1: a scent like slightly sweet corn tortillas, which seems to

38
00:02:15,200 --> 00:02:18,880
Speaker 1: intensify after dogs sleep, possibly because the heat generated by

39
00:02:18,919 --> 00:02:23,040
Speaker 1: a sleeping dog encourages bacterial activity. Even if you're not

40
00:02:23,080 --> 00:02:25,480
Speaker 1: a fan of corn chip pause, if some pet owners

41
00:02:25,520 --> 00:02:28,600
Speaker 1: call the odor freedo feet, your health may benefit from

42
00:02:28,600 --> 00:02:32,359
Speaker 1: exposure to doggy bacteria. Studies have shown that pregnant women

43
00:02:32,400 --> 00:02:35,680
Speaker 1: who own dogs have babies with a more diverse microbiome,

44
00:02:36,000 --> 00:02:38,400
Speaker 1: and that children who grow up around pets aren't as

45
00:02:38,440 --> 00:02:42,200
Speaker 1: prone to suffer from allergies. Most researchers agree that exposure

46
00:02:42,200 --> 00:02:45,640
Speaker 1: to a greater number of microbes enhances immune system functions.

47
00:02:46,320 --> 00:02:49,400
Speaker 1: No word yet on whether simply inhaling those microbes and

48
00:02:49,480 --> 00:02:52,680
Speaker 1: their byproducts by huffing puffy pause does the trick. It

49
00:02:52,720 --> 00:03:02,480
Speaker 1: can't hurt though right. Today's episode is based on the

50
00:03:02,560 --> 00:03:06,080
Speaker 1: article why your dog's pause smell gloriously like corn chips
