Anxiety or nervousness among dogs is not uncommon and usually falls into one of two categories: behavioral anxiety and situational nervousness. Behavioral issues are phobias or neurotic tendencies that can transfer into more general behaviors—a classic example being Separation Anxiety. Situational problems are more isolated, and can be highly individual to your dog’s personality.
In other words, if your dog is a homebody with a favorite spot on the couch, and you move house or throw away the sofa, you can expect a degree of situational nervousness. There’s many reasons why your dog may feel anxious – if over time, however, that nervousness becomes the norm, your dog might be suffering from a more general form of anxiety.
