Detailed profile of this breed: origin, year of creation, recognised varieties and official approvals.
Breed summary
I need to confirm which breed you mean. "Grand Russe" can refer to different Russian-associated rabbit types in various sources (for example, translations render it as "Russian Giant", "Great Russian", or it may be confused with breeds such as the Russian White). Reliable, consistent breed standards and quantitative data are scarce or inconsistent in available references. Tell me which exact name or a synonym you mean, and I will provide a detailed, sourced description in English including measurable characteristics (weights, sizes, conformation) and qualitative traits.
Detailed origin
I cannot provide a trustworthy detailed origin until you confirm the precise breed. Different Russian rabbit types have distinct histories (some developed as large meat/utility breeds, others as fur or show varieties). If you confirm the exact name or provide an image/link to a standard, I will summarize documented origin information with dates, regions, and breeder lines where available.
Detailed description
I prefer not to invent specifics. Once you confirm the exact breed (for example: "Russian Giant", "Russian White", or another synonym), I will deliver a full technical description: typical adult weights (with ranges and percentiles if available), body type and proportions, ear length, coat types and approved colors, temperament notes, reproductive and husbandry data (maturity age, litter size averages), and common health considerations, all with clear statements about the certainty and sources.
