The pet bed can become a receptacle for germs (including coliform, staphylococci, fungi) that are dangerous to the health of the pet and the whole family. And in addition to the bacteria and germs brought by the pet, dirt residues from the environment accumulate inside and can cause infections. Even if you can’t see them, pet beds host germs and bacteria that can put you at risk and expose your home to the risk of fleas, mites, ringworms, salmonella and listeria. Because fecal matter is very likely to be found in a pet bed, if your dog has a gastrointestinal parasite like giardia, roundworms or hookworms, there’s a risk that these can be transmitted to people and other pets in the household, too. Experts urge the need for regular bed washing, but how many do it? And, more importantly: How is it possible to know when the time is right?
