Healthy Rabbit Weight Chart by Breed
- Small breeds (Dwarf, Netherland Dwarf): 0.8–2.0 kg (ideal ~1.2–1.6 kg)
- Medium breeds (Rex, Holland Lop): 2.0–4.0 kg (ideal ~2.5–3.2 kg)
- Large breeds (Flemish Giant, French Lop): 4.0–6.5 kg (ideal ~4.5–5.5 kg)
Use our rabbit weight calculator above to compare your bunny’s weight against breed-specific ideal ranges. Obesity leads to arthritis, flystrike, and heart disease; underweight indicates dental problems or chronic illness.
Rabbit Age to Human Years Formula
First year = 20 human years, second year = 30 human years, then +5 per year for medium breeds (small +4, large +6). A 4-year-old medium rabbit ≈ 40 human years. Senior rabbits (6+ rabbit years) need bi-annual vet visits.
Common Health Issues by Weight & Age
- Underweight: Dental disease, kidney failure, parasites, cancer
- Overweight/Obesity: Pododermatitis (sore hocks), arthritis, hepatic lipidosis
- Senior rabbits (6+ years): Osteoarthritis, renal insufficiency, GI stasis risk
