Pet Weight & BMI-Style Reference Tool

Quickly check whether your pet’s weight is underweight, ideal or overweight based on typical adult weight ranges. This tool uses a simple “weight index” (similar to BMI) plus a reference chart for many common pets. It is for general guidance only and cannot replace a professional veterinary assessment.

Reference weight ranges for common pets

The tables below summarize approximate ideal adult weight ranges for many popular pet types and size groups. These values are based on typical healthy adults living in good conditions and are meant as a starting point for discussion with your veterinarian, not as strict limits.

Notes:
• Ranges may differ by sex, neuter status, breed line and activity level.
• Many mixed-breed animals fall between size categories; choose the closest profile and focus on body shape, muscle tone and energy level in addition to weight.

Disclaimer: This pet weight and “BMI-style” tool is designed for educational use only. It does not diagnose disease or replace a full veterinary body condition assessment. Always seek professional advice if you are worried about your pet’s weight, appetite, activity level or overall health.
