Dogs routinely dig for several reasons, all of which can be seen as instinctual behaviors that they got from their ancestors. One reason your dog may be digging into the couch is due to how dogs would dig out dens in the wild as a place to rest and protect themselves from various predators. Another reason may be due to your dog wanting to conceal the place where they sleep, like animals do in the wild.
Like us, dogs cough to get rid of dust, germs, and other stuff they breathe in. Also like us, they sometimes get infections or viruses. Dogs are social creatures that naturally sniff and slurp. This is why bacteria and viruses â including a canine form of the flu -- quickly spread from dog to dog. Germs also can land on floors, furniture, food bowls, toys, and other surfaces where the next dog to come along picks them up. Kennel cough is the common name for a deep, honking canine cough.
