What Makes a Dog Eligible for Size Records
To qualify for size records, dogs must be measured by a licensed veterinarian using standardized methods. Records consider full-grown height at the shoulder and body length, excluding the neck and head. The dog must be in good health and verified as the smallest of its breed or overall. Guinness World Records requires documented proof, including photos and veterinary certificates. The smallest dog title can change as new measurements are submitted and verified globally. The
