DOG ANXIETY: CAUSES
There are a variety of reasons why your dog has anxiety. The most commonly seen by Veterinarians are fear, separation and aging.
For example, maybe your dog is forced into an unfamiliar or frightening experience to them, or they have a fear of abandonment, or maybe they have had bad experiences in the past or were not given the correct social and environmental exposure from a young age. These are all very common examples of what causes anxiety in dogs.
