84% of Dogs Show Fear or Anxiety? What the 43,517-Dog Study Really Measured
A Texas A&M study of more than 43,000 dogs made headlines in May 2026 with one number: 84%. Here is what that number counts, what it doesn't, and the most common fears owners reported.

The 2026 study behind the “84% of dogs” headlines did not find that most dogs have anxiety. It found that owners of 43,517 dogs in the Dog Aging Project rated at least mild-to-moderate fear in 84% of them, in at least one of seven everyday situations, like meeting an unfamiliar dog or hearing a sudden noise. It’s a useful reminder of how common fear is, and a bad basis for assuming your dog has a disorder.
The study in one paragraph
Dr. Bonnie Beaver of Texas A&M published it in Veterinary Research Communications (online April 25, 2026). She used 2022 survey answers from owners of 43,517 U.S. dogs enrolled in the Dog Aging Project. Owners rated nine items from a standard behavior questionnaire (the short C-BARQ) on a scale from 0 (no fear) to 4 (extreme): reactions to unfamiliar people, unfamiliar dogs, noises, objects and new situations, plus two grooming items such as nail clipping.
What the numbers actually count
- 91% of dogs scored at least “mild to moderate” fear on at least one of the nine items.
- 84% did so when the two grooming items are left out. That’s the headline number.
- Only 3 dogs out of 43,517 were rated extreme on all nine items. Among dogs with any non-grooming fear, about 6 in 10 (59.7%) showed it in more than one situation.
So the bar is low (one mild-to-moderate reaction in one situation is enough), and the extreme, fearful-of-everything dog is rare. Both things are true at once.
What dogs were most afraid of
By category, the share of dogs with at least mild-to-moderate fear:
| Situation | Dogs |
|---|---|
| Unfamiliar dogs | 47.4% |
| Grooming (for example, nail trims) | 33.0% |
| Unfamiliar situations, objects or noises | 25.5% |
| Unfamiliar people | 22.3% |
Among the single items, sudden or loud noises and nail clipping by someone at home were the ones owners most often rated as extreme. If your dog panics at the clippers, you’re in big company.
What it does not show
It is not a diagnosis. The paper says plainly that the survey is “not intended to be diagnostic,” and Texas A&M notes the findings don’t mean most dogs have clinical anxiety disorders, or tell us which dogs need treatment.
It says nothing about separation anxiety. The questionnaire had no item about being left alone. You’ll see the 84% paired with separation anxiety online; that pairing isn’t supported by this study.
It isn’t a random sample. The dogs belong to owners who volunteered for the Dog Aging Project, surveyed in one year. That’s a large group, not necessarily a typical one.
Why it’s still worth reading
The useful point is the one Dr. Beaver makes about vet visits: “Behavior is an area that often doesn’t come up unless the owner brings it up first.” Fear that shows up now and then is normal; in her words, “When that fear becomes chronic, that’s when it starts to impact their overall well-being.” Those are the cases worth a conversation.
If you want to put words to what you’re seeing before that visit, the free body-language decoder helps you read the signals, and the two-minute tests for noise fear, separation anxiety and leash reactivity turn a vague worry into specific answers you can bring to your vet. For fireworks fear specifically, the FDA also approved a prescription drug in 2026, expected in U.S. clinics around mid-2027; my article on Tessie covers what its trials showed.
Frequently asked questions
- Do 84% of dogs have anxiety?
- No. The 2026 study found that owners rated at least mild-to-moderate fear in 84% of dogs in at least one of seven everyday situations, such as meeting an unfamiliar dog or hearing a sudden noise. The author stresses the survey was not diagnostic, and Texas A&M notes it doesn't mean most dogs have clinical anxiety disorders.
- What are dogs most afraid of?
- In this study of 43,517 dogs, unfamiliar dogs were the most common trigger (47.4% of dogs showed at least mild-to-moderate fear), followed by grooming (33%), unfamiliar situations, objects or noises (25.5%) and unfamiliar people (22.3%). Sudden or loud noises and nail trims at home were among the items owners most often rated as extreme.
- Did the study look at separation anxiety?
- No. The survey had no question about being left alone, so the 84% says nothing about how common separation anxiety is. If you're wondering about separation anxiety, that's a separate question for your vet.
- When is fear a problem?
- The study's author, Dr. Bonnie Beaver, puts it this way: 'When that fear becomes chronic, that's when it starts to impact their overall well-being.' A dog that is scared now and then is different from one that lives on edge. If you're unsure, raise it with your vet.
