No matter what age the dog is, eating a raw meat diet causes them to pass antibiotic resistant Escherichia coli (E.coli) in their feces which can be transmitted to humans.
Researchers from the University of Bristol conducted an in-depth study of 823 dogs of all ages.
They found that dogs who lived in the country had a strong risk factor in passing antibiotic resistant E.coli but dogs who live in the city had more complicated risk factors that may be linked to the variety of lifestyles and exposure to other dogs.
E. coli is found in the intestines of both humans and animals and is a common cause of various diseases including urinary tract infection and can cause sepsis in other parts of the body.
The bottom line is that feeding raw meat to dogs is not safe for both the dog and humans. If a dog owner insists on feeding raw meat to their dog, they must be very careful of infection.
