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.
A weak, gagging, high-pitched cough that is followed by licking and swallowing typically is caused by a sore throat and perhaps tonsillitis. A dog that has long bouts of coughing, usually at night while lying down, may be suffering from heart disease â particularly congestive heart failure. In toy dogs, a chronic dry, harsh, âgoose-honkingâ cough often is caused by a collapsing trachea. Dogs with a soft cough and a high fever may have contracted canine influenza, which is a fairly recently recognized disease of domestic dogs.
