Behavioral disorders can have two distinct origins:
Medical in origin — linked to a pathology, an injury, or the development of a disease.
In this case, only a visit to a veterinarian—or even better, to a veterinary behaviorist—can establish an accurate diagnosis and prescribe an appropriate treatment.
Behavioral in origin — linked to the expression of anxiety, a lack of structure or reference points, or poor communication within the dog’s immediate environment.
In this situation, the issue falls within the scope of education and the human–dog relationship.
A visit from a canine behaviorist and trainer will help analyze the underlying causes and propose practical, tailored solutions. Ideally, this assessment should take place in the very context where the behavior occurs, or at least within the dog’s usual living environment, in order to fully understand all contributing factors.
