it doesn’t make her actually chew her food.
normal dogs don’t chew the way people and horses do. Dogs don’t even have “chewing teeth” in their mouths. Dog teeth are all sharp knives intended to slice chunks of meat off prey. If you watch a dog eat a natural prey animal, you’ll see them use their teeth to slice huge chunks of meat off, which they swallow. Dogs can swallow alarmingly large hunks of meat. I had a big dog swallow an entire small rabbit once, fur, bones, ears, and all, and it digested just fine.
So if you give your dog food that is already in tiny little pieces, like kibble, of course the dog doesn’t chew it. He doesn’t have any teeth that are able to chew that kind of food. They get it into their mouths and just swallow it. Which is why it’s kind of funny when some people go around claiming kibble cleans teeth- of course it can’t.
So it’s completely normal for dogs to “inhale” bowls of food.
Feeding a dog in a way that makes the dog “work” to eat has many mental benefits though, everything from staving off boredom to improving work ethic to reducing chances of the dog getting overweight.
I prefer the balls like the Kibble nibble or the buster cube that the dog has to actively move around with, or the “puzzles” they have to use their brains to work at.
Or some people just go low-tech and just throw handfuls of kibble out in an area for the dog to run around and find.
