Dog Aging Project study points to end-of-life education gaps
A new Journal of the American Veterinary Medical Association study from the Dog Aging Project offers a closer look at how pet parents perceive canine death, and where veterinary teams may need to do more teaching. In 646 analyzed End of Life Survey responses, 83.0% of dogs were euthanized, most commonly in a veterinary clinic or at home, while 14.7% died without veterinary involvement. Pet parents most often identified cancer, “old age,” and organ system disease as the cause of death, and they most often cited pain and suffering as the main reason for choosing euthanasia.

The work builds on the Dog Aging Project’s broader effort to capture not just medical data, but also the human perspective around late-life care. The owner-facing End of Life Survey was previously developed and validated to collect information on timing of death, quality of life, veterinary involvement, euthanasia decisions, and perceived cause of death. That structure matters because what pet parents notice, understand, and report can directly affect mortality data and the clinical story veterinarians hear at the end of a dog’s life. (drjingma.com)
In the new study, researchers invited 793 pet parents whose dogs died during the study window to complete the survey; 655 responded, for an 85.7% response rate, and 646 responses were included in analysis after exclusions. Mean age at death was 13.0 years. Among euthanized dogs, 76.7% were euthanized in a veterinary clinic and 22.8% at home. Perimortem quality of life was negatively associated with age at death, and owner-perceived cause of death varied by age group. (pubmed.ncbi.nlm.nih.gov)
Additional context from Texas A&M’s March 24, 2026 press release ties this paper to a second Dog Aging Project study on grief after canine death. In that related analysis, owners reported similar levels of grief, guilt, and blame whether a dog died by euthanasia or unassisted death, with sudden death mentioned more often in unassisted cases. Researcher Jake Ryave said he expected more severe negative emotions after unassisted death, but that difference did not emerge, underscoring how strongly the human-animal bond shapes bereavement regardless of circumstances.

The same press release also surfaces a practical message for clinicians: pet parents often described vocalization, mobility changes, depressed mentation, or subtle behavioral cues when deciding a dog was suffering, yet some appeared to have difficulty distinguishing pain from normal aging. McNulty said the findings suggest owners may not fully understand how to recognize pain or aging symptoms, and the release noted that some respondents reported prognosis was not discussed, or not fully understood, during veterinary visits near the end of life.

Why it matters: For veterinary professionals, this is less a story about euthanasia rates than about communication quality. If pet parents are using broad labels like “old age,” or relying on subtle behavioral impressions to assess suffering, practices may need more structured conversations around chronic pain, cognitive decline, mobility, prognosis, and quality-of-life monitoring. The findings also support normalizing grief resources for all bereaved clients, including families whose dogs die outside the clinic, because emotional fallout may be similar even when the clinical circumstances are not. That has implications for discharge protocols, end-of-life handouts, technician follow-up, and how teams frame anticipatory guidance for senior dogs. (pubmed.ncbi.nlm.nih.gov)
What to watch: The Dog Aging Project authors said future analyses will further examine owner perceptions around cause and manner of death. For practices, the near-term takeaway is actionable now: clearer pain education, earlier quality-of-life discussions, and grief support pathways that don’t depend on whether euthanasia happened in the hospital.
