10 Gross Reasons To Not Share Your Bed With Your Dog

4. Fecal Matter

Dogs are not exactly the cleanest of animals. Some dogs may play with, step in or even eat their poop. When they trample in your house and head straight to your bed, they are tracking fecal matter along with them, which may attract parasites and bacteria such as salmonella and E. coli to your sheets. To make sure your dog doesn’t drag anything in from the outdoors, try wiping his or her paws with water and rubbing alcohol to kill any germs.
