Anxiety disorders in dogs may be brought about by illness, previous stay at a rescue center, separation and/or being reclusive; other potential triggers include separation or being left alone too long. A dog suffering from anxiety disorder often exhibits behavior such as tucking himself between its legs and avoiding eye contact; inappropriate elimination occurs as well as destructive behavior and aggressive vocalization. Therefore it’s advised that you seek advice from a veterinarian.

If your dog tucks their legs between his legs frequently or seems restless most of the time, avoids eye contact, and prefers retreating in its kennel, it could be indicative of mental disorder. While these behaviors don’t necessarily indicate mental illness in all instances, if observed it would be wise to consult your vet regarding this possibility if seen acting this way.
