Nearly All U.S. Dogs Exhibit Behavior Issues, According to Texas A&M Study
Dr. Bonnie Beaver, a researcher at the College of Veterinary Medicine & Biomedical Sciences (VMBS), has discovered that over 99% of dogs in the United States display behaviors that could be considered problematic. While many owners view these issues as minor or not worth tackling, the research underscores how common such challenges are in canine companionship.
Published in the Journal of Veterinary Behavior, the study draws on data from the Dog Aging Project (DAP), a nationwide effort tracking over 50,000 dogs to explore aging and health in pets. Owners participating in DAP rated their dogs’ behaviors across 28 questions, using a scale from zero (no issue) to four (potentially severe). The most frequent concerns included separation and attachment issues (85.9%), aggression (55.6%), and fear or anxiety (49.9%).
“Across the board, 99.12% of dogs showed at least one behavior rated as moderate to severe,” said Dr. Bonnie Beaver, a professor in VMBS’ Department of Small Animal Clinical Sciences and the study’s author. “Most responses indicate that dogs don’t have overwhelming problems, and the issues that do arise are often small. Owners might not see them as pressing, but nearly every dog owner will face some behavior that’s at least mildly disruptive.”
Beaver emphasized that the survey questions aren’t diagnostic tools, and behaviors often overlap. “Anxiety and separation issues can be linked, yet they were categorized separately,” she explained. “A dog might bite out of fear, but fear and aggression were also split into different sections. This means a fear-biting dog might not stand out clearly in the data.”
The takeaway? Behavior is a fundamental aspect of owning a dog, deserving attention from both owners and veterinarians to keep mild quirks from escalating.
Uncovering the Source of Canine Behaviors
Behavioral challenges can be tricky to address since not every owner perceives them the same way. “Take a miniature poodle I once treated,” Beaver recalled. “It barked excessively, which bothered the owner, but the fact that it regularly urinated on a Persian rug didn’t faze them as much.”
Veterinarians may need to dig deeper to get the full picture. “Owners don’t always mention behavior issues unprompted,” Beaver noted. “If a dog snaps at someone on the way out of the clinic, they’ll bring it up. But if it happened months ago, it might not cross their mind.” She suggests giving owners a questionnaire before appointments to jog their memory and encourage disclosure.
When Behaviors Turn Risky
While many canine quirks are harmless, some demand urgent attention. “Every species has behaviors humans don’t fully grasp,” Beaver said. “If it’s dangerous to you or others, you need assistance—and you should examine what in the dog’s environment might be sparking it.”
Aggression—think growling, snapping, or biting—is among the most concerning behaviors, though its triggers aren’t always obvious. “Aggression is natural for animals and serves a purpose,” Beaver said. “Is the dog scared? Threatened by a child getting too close, someone staring it down, a larger dog approaching, or a stranger nearing? We have to consider the context to understand what’s happening in the dog’s head. Animals think—just not necessarily like us.”
Beaver stresses that learning to read a dog’s body language is key to preventing aggression. “Resources are out there online, including from vets, and your local veterinarian can provide visuals or tips,” she said. This is especially critical for households with young kids, who are most vulnerable to bites. “Children under 7 are the most frequent victims,” Beaver warned. “If you have kids and a dog, supervise their interactions. Don’t let children climb on the dog or tug at its ears, and teach them not to approach any dog—even the family pet—without an adult present.”
Bridging the Gap in Veterinary Care
The study highlights a gap in addressing behavior: “Some research shows only half of veterinarians ask about it during visits, and owners might not think to raise the topic,” Beaver said. “We need to shift that mindset to catch problems early.” She urges owners to consult their vet about any bothersome behavior. “They can pinpoint the cause and suggest solutions,” she added.
Ultimately, Beaver’s findings reveal that while behavior issues are nearly universal among U.S. dogs, proactive steps—from owner education to veterinary dialogue—can keep them manageable, ensuring happier homes for both pets and people.
