Five rules for talking about pet obesity

The standard in one sentence: communicate about pet obesity as a medical condition, using pet-first, nonjudgmental, evidence-based language that focuses on health, body condition, quality of life, and veterinary-supported care.

  1. Name the pet first

    Say “a dog with obesity,” not “an obese dog.” The condition is something the pet has, not what the pet is. The same applies to people: “a person with obesity.”

  2. Use the four terms precisely

    Overweight, obesity, preclinical obesity, and clinical obesity are not interchangeable. Excess adiposity is a finding; clinical obesity is a diagnosis. Definitions are below.

  3. Lead with body condition, not body weight

    Report body-condition score and muscle condition, and frame progress as improved body condition, mobility, and quality of life rather than pounds lost.

  4. Treat obesity as a multifactorial disease

    Genetics, hormones, comorbidities, environment, diet, and activity all contribute. Do not reduce it to overfeeding, and do not assign blame to owners or pets.

  5. Choose respectful images and stories

    Show health, dignity, and veterinary partnership. No ridicule, no “before and after” built on weight alone, and label AI-generated images as such.

2026 definitions

The four terms

A body-condition score identifies excess body fat. Whether that excess has become a disease in this patient is a separate clinical question, answered by a documented abnormality and plausible attribution, not by the chart alone.

Usually BCS 6–7/9

Overweight

A body-condition category, not a disease stage: more body fat than the ideal range but below the usual obesity range, with no obesity-related dysfunction established by body-condition score alone.

Weight management begins here.

Usually BCS 8–9/9

Obesity (descriptive)

Documented excess adiposity recorded before the clinical classification has been completed: a clinically important finding and a potential disease process, but not yet a disease-stage diagnosis.

Use it whenever the assessment has not yet been done.

Obesity range, no linked illness found

Preclinical obesity

Excess adiposity in the obesity range with preserved function of tissues and organs, carrying an increased risk of progression to clinical obesity and to other adiposity-related diseases.

Not “metabolically normal,” and not a reason to wait: begin structured weight management and reassess.

Adiposity + abnormality + attribution

Clinical obesity

A chronic, systemic illness in which excess adiposity in the obesity range alters the function of tissues, organs, or the whole animal, or diminishes quality of life, in an individual dog or cat.

All three A’s must be documented in that patient. Treat adiposity as a therapeutic priority alongside concurrent conditions.

The clinical framework behind these terms, including how to stage a patient, is in the WPOA guide to diagnosing and classifying clinical obesity.
