What's In Dog Food?

Have you ever thought about how strange it is that dogs eat these dry, weird smelling bits of food for their entire lives and never get sick of them? This truly is a scientific puzzle and there are many different types of dog food formulas on the market. Some are designed for weight loss, long shelf life and making sure that your dog eats a balanced diet. This week on Reactions, you’ll see the real wonder of what’s behind the chemistry being used to make the perfect dog food kibble.

    Kibble is trash. Give your fur babies natural food. Meat, sweet potatoes, string beans, eggs, etc. Kibble is processed food, and therefore, unhealthy.

  2. Shiruki on May 7, 2021 at 1:46 pm

    Just Google "how it’s made kibble". Kibble is really bad for pets. There’s plenty videos, articles, sources and all kinds of information how raw food is in every way much healthier for pets. If you choose not to educate yourself you’re straight up ignorant and keeping your pets from a healthy lifestyle. Kibble is like fast food, unhealthy and full of fillers.

    Dog kibble would be like if a human tried to live off of doritos and multivitamins, completely unnatural. This propaganda is harmful to animals.

    This is my favorite channel 😊

  5. Sagacious Apotheosis BLM on May 7, 2021 at 1:51 pm

    We supplement our dogs food with cooked meals. They love it when we make them fresh food. Somehow when we cook fresh, some kibbles are always left behind. 😉 🐶 ❤️

    it’s odd that putrescine and cadaverine smell bad to us given that a large part of human history was eating left over bone marrow which I can’t imagine smells much better.

    Pet question: What is aquarium dechlorinator, and would it be safe to use on water you were going to brew beer or kombucha with?

  8. Gabriel Cazorla Persson on May 7, 2021 at 1:54 pm

    i dont even have a dog, why am i watching this?

  9. francis bélanger on May 7, 2021 at 1:56 pm

    I love Nahre Sol’s channel ! What a great news that she’s in _Sound Field_ !

  10. Karen Lamb on May 7, 2021 at 2:00 pm

    Disgusting. Give them real food. Meat, eggs, fish…..

  11. Holly Leeming on May 7, 2021 at 2:02 pm

    How to use your bag of kibbles, 1 open bag, 2 pour it directly in the Garbage can. Corn in dog food is healthy? Dogs are getting no nutrients from corn, just like humans dogs cannot digest corn, neither can dogs. Also corn isn’t even nutritional for humans unless eaten uncooked, and dogs are not eating the good part of the corn they are putting what’s left after the corn is processed. Do the salt divider test on your kibbles, anything after salt on the bag means your dog is getting less than 1% of each item in their kibbles, such as blueberries, if they advertise anti oxidants in your kibbles look at ingredients and see if it comes after salt, if it does the odds are you are getting less than a handful in a bag.

    Then why do they give grains to dooogs?

  13. Winona Daphne on May 7, 2021 at 2:05 pm

    i never liked the chemistry classes at my high school, but i just subscribed to this channel because it presents information in a fascinating and fun way

  14. Daedhart on May 7, 2021 at 2:06 pm

    What is up with that bowl tho? Make em work for their meal, I guess.

  15. Aaron Mcroodle on May 7, 2021 at 2:07 pm

    Most Kibble is crap, just like this video. Please watch pet fooled documentary.

  16. dininghalllurker on May 7, 2021 at 2:08 pm

    Sure shot cancer

  17. Tipakorn Greigarn on May 7, 2021 at 2:09 pm

    Cheetos is basically dog food for human then.

  18. ythorus on May 7, 2021 at 2:10 pm

    As a nutrition scientist, I have answered questions about the way that animals, particularly dogs, can eat foods that would be considered spoiled for human consumption, yet the treatment and shorter time it spends in the canine digestive system make it less likely to make them ill. This coupled with their ability to summarily reject items at one point (we know what that means), or eat grass to provide another way to mitigate some of the risks, is another. All fascinating stuff for the dog owner.

  19. Yafet Kasalie on May 7, 2021 at 2:11 pm

    Make a natural food than those weird dog food

  20. clindberg1 on May 7, 2021 at 2:13 pm

    you should do a video on how reusable hand warmers work (the ones with the metal inside)

  21. Anelia Guteva on May 7, 2021 at 2:18 pm

    My current dog, like all my other previous dogs, absolutely loathes dog food. Whatever it is that scientist have done to trick dogs into eating dog food, it is not working.

  22. robloxplayer123 on May 7, 2021 at 2:18 pm

    Flamingo made a video and told us its made by horse is that true?

  23. L. Maris on May 7, 2021 at 2:18 pm

    So kibble is mostly grains that dogs wouldn’t normally eat and can’t easily digest but we cook them and add an attractive smell so they do eat it? That doesn’t sound very good for dogs.

    When did the kibble industry start? Why do our dogs need to eat that? Why don’t we just feed our dogs leftovers and meat and bones like people used to? I know my dogs don’t really like kibble, they eat it because that’s what they have to eat. But when they eat meat and eggs, they DEVOUR them because they are so delicious.

  24. MrD1ss on May 7, 2021 at 2:18 pm

    Sad idiots BELIEVE videos made by suits selling this shit. This is lies. Anything that can sit in a cuboard fir 2 years… is 100% poison

  25. Kai Thetechnicolorninja on May 7, 2021 at 2:20 pm

    Do that for humans then we can decide.

  26. Tanya's Obsessions on May 7, 2021 at 2:20 pm

    if you want to learn more about pet food, please watch the documentary called Petfooled. it’s SO good! taught me a lot about the industry as a whole! mind blowing stuff!!

  27. Maher AlMahdy on May 7, 2021 at 2:21 pm

    Informative footage , nuf would you shed some light on the details of the palatability materials ?

  28. Cpk19 on May 7, 2021 at 2:21 pm

    Just stick with raw food guys

  29. David Rowland on May 7, 2021 at 2:21 pm

    So they add a lot of starch which turns into sugar when eaten, then cook this stuff to death so there’s no flavor, then hire chemists to spray chemicals on the kibble so they will eat this garbage. Wonderful, no wonder more than 50% of dogs are getting cancer.

  30. Shanyi Alexander on May 7, 2021 at 2:22 pm

    Balanced and freshly cooked meals hands down.

  31. Jess S on May 7, 2021 at 2:23 pm

    In summary, kibble is made of a bunch of food dogs aren’t supposed to eat to make it cheap, sprayed with chemicals to make it smell yummy when really its bland and flavourless and thats all they eat for the rest of their lives? Glad I’m not a dog

  32. Ikenna O on May 7, 2021 at 2:23 pm

    It’s a lie, we can never know they like them, dog food is trash, variatize your dogs food

  33. Alexi Xeno on May 7, 2021 at 2:25 pm

    I was going to ask if they were ever going to make a human equivalent.. then I remembered Mcdonalds existed, except it’s not healthy.

  34. asianpersuasion on May 7, 2021 at 2:31 pm

    This video has to be joke, a whole diet of highly processed food full of carbs and starch isn’t good for anyone 🤦🏽‍♀️ we get told that a healthy diet should consist of a variety of whole fresh foods and to limit processed and refined foods, yet it’s somehow healthy for dogs? It just doesn’t make any sense.

  35. Dylan23 on May 7, 2021 at 2:32 pm

    I think it smells pretty good.

  36. Dragon Skunk Studio on May 7, 2021 at 2:37 pm

    That ad transition tho.

  37. Sound Field on May 7, 2021 at 2:37 pm

    Thanks for the love Reactions! I’d be interested in a human meal designed like dog food that’s as cheap and easy to prepare…

  38. Lily on May 7, 2021 at 2:40 pm

    Am I the only one who thinks dog food smells good? ;c

  39. Jason on May 7, 2021 at 2:40 pm

    Would these factors apply to cat food too?
