The Rat Terrier is a compact terrier breed originating from United States, known for being alert, curious, and lively. Weighing 5–11kg and standing 25–46cm at the shoulder, they typically live 12–18 years. Rat Terriers require moderate daily exercise and very low-maintenance grooming to maintain their short smooth coat. They are well-regarded as a family breed and typically patient with children. Their adaptable nature makes them a reasonable choice for apartment living, provided their exercise needs are met.

Patellar luxation occurs when the kneecap slips out of its normal groove in the femur. It can be medial (inward) or lateral (outward) and ranges from grade 1 (occasional slipping) to grade 4 (permanent dislocation).
Typical onset: 4 months - 6 years
Hip dysplasia is a genetic condition where the hip joint doesn't develop properly, causing the ball and socket to not fit together correctly. This leads to joint deterioration, pain, and arthritis over time.
Typical onset: 1-2 years
Nutrition is a cornerstone of Rat Terrier health. An adult Rat Terrier weighing 5–11kg typically requires 500–600 kcal of high-quality food per day, split across two meals to support consistent energy levels and healthy digestion. Small breeds can experience hypoglycaemia if meals are skipped; regular feeding times are especially important for Rat Terrier puppies. Always adjust portions based on your dog's individual weight, life stage, and activity level, and consult your vet before making significant dietary changes.
Full Rat Terrier Feeding GuideThe Rat Terrier has moderate exercise requirements. Plan for at least an hour of brisk walks, play sessions, and occasional off-lead runs every day to keep your Rat Terrier physically healthy and mentally settled. Rat Terriers are highly intelligent and benefit considerably from mental stimulation alongside physical exercise — training games, scent work, and puzzle feeders can all help prevent boredom-related behaviours. Although they can adapt to apartment living, Rat Terrier owners without a garden should plan to provide at least an hour of outdoor exercise daily without fail.
