➥RAW, LIGHTLY COOKED, EXTRUDED DOG FOODS ALTER GUT BACTERIA
That finding likely resulted
from the acidity of the raw diet.
Both Lactobacillus and Pediococcus
species were acid-tolerant strains.
That acidity of raw diets helps limit
pathogen growth in the dog foods,
"The raw diet tested in our study
is unique in its acidity (low pH),"
he said. "During its preparation,
it undergoes an incubation with
Pediococcus acidilacticii, a lactic acidproducing bacteria used in human
foods (and this pet food). The acidity
kills potential pathogens. Therefore, it can be safe from a pathogen
perspective without undergoing high
pressure pasteurization (HPP) like
many of the raw diets on the market.
"In regards to fecal microbiota,
the increase in Pediococcus and
Lactobacillus observed in dogs fed
raw diets in our study is probably unique to this particular raw
diet because of the acidity of the
food and because the food is a
source of Pediococcus (so it may act
like a probiotic in that sense)."
and the pet food industry has
advanced over the past few decades.
"Whether the ancestors of
domestic dogs were consuming
animal carcasses, feeding off
humans' scraps, or consuming
plant matter, we need to prioritize and use our current scientific
knowledge to feed our pets of

Raw versus cooked pet food
and dog biology
Because all three types of dog
food didn't seem to result in health
problems, one takeaway from this
research may be that extruded,
lightly cooked and raw dog foods
can all meet dogs' nutritional needs
if made using evidence-based
guidelines and safety protocols.
"While some may suggest that
one type of diet is the only way to go,
dogs are living longer than they ever
have before," said Swanson. "This
shows how much the scientific
