Question

Which of the following is known to be TRUE about dog owners and their dogs?
A) Dog owners have fewer skin microbes than those who don't own dogs.
B) Dog owners have more skin microbes than those who don't own dogs.
C) Skin microbes are more common between dog owners and their own dogs than between dog owners and other dogs.
D) Skin microbes are similar between dog owners and dogs in general, with no difference in similarity when dogs and their owners are compared with other human-dog pairs.

Accepted Answer

Studies have shown that dog owners do have a higher amount and diversity of skin microbes, but these microbes are more similar to those found on their own dogs rather than on other dogs. This suggests that close contact and sharing of skin microbes between dogs and their owners is a factor in the microbial makeup of their skin.
