New Study Finds Over 84% of Dogs Show Signs of Fear or Anxiety

New research indicates that a vast majority of dogs experience some level of fear or anxiety more frequently than their owners may realize. A study analyzing behavioral data from tens of thousands of pets across the United States found that more than 84% of dogs showed at least mild signs of fear or anxiety in everyday situations.

The findings exclude learned fears associated with specific grooming activities, such as bathing or nail trimming. Instead, the research focuses on how dogs respond to common, real-world stressors.

The study was conducted by Bonnie Beaver, a professor of behavior in the Department of Small Animal Clinical Sciences at the Texas A&M College of Veterinary Medicine and Biomedical Sciences.

Comprehensive Behavioral Data

To gather this data, Beaver utilized the Dog Aging Project, a large-scale national research initiative that collects owner-reported information on dogs. By examining the behavioral responses of more than 43,000 animals, the study created one of the most comprehensive datasets to date regarding canine fear and anxiety.

Because the data relied on observations from owners rather than clinical diagnoses in a controlled environment, the results reflect how dogs behave in their actual living conditions.

Beaver noted that while this approach introduces some variability, it provides valuable insight into how frequently dogs encounter and respond to common stressors in their daily lives.

These are behaviors most owners have seen at some point, Beaver said. What this research shows is just how common those responses are—and how important It’s that we pay attention to them.

Common Triggers and Health Impacts

The research identified unfamiliar dogs and unfamiliar people as some of the most frequently reported triggers for fear and anxiety. These are situations that many pets encounter on a regular basis.

While short-term fear is a common experience for both humans and dogs, the study emphasizes the danger of chronic stress. When fear becomes a long-term or repeated activity, it can begin to impact a dog’s overall well-being.

Long-term stress has been linked to negative effects on the immune system, as well as a decrease in a dog’s overall quality and length of life. This connection makes the early recognition of anxious behaviors particularly critical for long-term health.

Escalation and Severe Distress

In more severe instances, fear can escalate significantly if dogs are repeatedly exposed to stressful environments without proper support. This escalation can lead to extreme behavioral responses.

I’ve seen dogs get to the point where they’re so distressed during storms that they try to chew through brick walls just to get into their house, Beaver said. Once it reaches that level, it is almost impossible to manage.

without intervention, fear-based behaviors may increase the risk of aggression. When dogs are repeatedly placed in uncomfortable situations, such as forced interactions with strangers, they may eventually resort to aggression as their only known way to respond.

Integrating Behavior into Veterinary Care

Despite the prevalence of these behaviors, they are often overlooked during routine veterinary visits. Beaver observed that behavioral concerns typically only enter the conversation if the owner brings them up first.

To address this gap, she suggests that veterinarians incorporate behavioral screening tools into their practice. This could include questionnaires that owners complete before their appointments to help identify concerns earlier and encourage proactive conversations.

Identifying when fear has transitioned into a clinical concern often depends on observing changes in the intensity and duration of the behavior. Owners are encouraged to seek professional guidance if they notice that a dog’s reactions are lasting longer or becoming more intense.

While the study does not suggest that the majority of dogs suffer from clinical anxiety disorders, it clarifies the frequency of fear and anxiety across a diverse population. Because of the size of the dataset, the findings are not limited to specific breeds, sizes, geographic areas, or types of clinical cases.

The research was supported by the WoodNext Foundation, an organization that provides grants and investments for mental health, scientific and biomedical research and other social and environmental causes.

The ultimate goal of the research is not the total elimination of fear, but rather its recognition and monitoring. By identifying consistent or increasing fear early, owners and professionals can step in before the behavior escalates.
