Dogs have a much higher tolerance to bacteria than humans. Think about all the times that you have seen your dog sticking their nose in dirty things, drinking out of puddles or eating stuff off the ground!
Dogs have three things that help them deal with harmful bacteria:
Saliva that contains bacteria-fighting enzymes.
Highly acidic gastric juices that break down bacteria in their stomach.
A short digestive tract that is able to quickly process what they eat.
Your dog can handle a certain amount of bacteria without any issue. Any high quality commercial raw pet food should be no problem, but it’s important to avoid raw pet food that people make cheaply or sell out of their homes. Remember that not all raw diets are created equal.
