Overview
- The French Lop is the giant of the lop family, developed in France around 1850 by crossing the English Lop with giant breeds such as the Flemish Giant.
- Adults typically weigh 4.5-6.8 kg, three to four times the size of a Holland Lop, with a massive head, heavy bone and thick, horseshoe-shaped ears that hang just below the jawline.
- That combination means the breed stacks two sets of care considerations at once: the space, food and sore-hock risks of a giant alongside the ear and dental issues common to lops.
- Like most giant breeds it also lives a shorter life than smaller rabbits, usually 5-8 years.
- It is famously placid, but its sheer size and strength make it a poor first rabbit.
- If you cannot commit room-sized space and giant-breed running costs, a smaller lop or no rabbit yet is the honest answer.
Housing
- No standard cage or hutch is remotely adequate for this breed.
- Modern welfare guidance sets 3 x 2 m of permanently accessible space with 1 m of headroom (6 m²) as the minimum for any pair of rabbits, and a French Lop pair should have more: free-roam access to a room, or a pen well above that footprint, plus a large secure run for daily exercise.
- Furnish at giant scale, with oversized litter trays, hides big enough to turn around in, and heavy tip-proof bowls.
- Soft, clean, non-slip flooring is essential, because their weight makes pressure sores on the hocks a constant threat on hard, wire or abrasive surfaces.
- Bare laminate and thin fleece over concrete are common mistakes.
- Keep them cool and well ventilated, since heavy-bodied rabbits overheat quickly and struggle above about 25°C (77°F).
- A determined 6 kg rabbit can flatten flimsy pen panels, so use sturdy fencing and rabbit-proof cables and skirting indoors.
Diet
- Unlimited grass hay must form the bulk of the diet to keep the continuously growing teeth worn and the gut moving, topped with a generous daily portion of washed leafy greens and a measured pellet ration of roughly 25 g per kilogram of body weight.
- Expect to buy hay in bale quantities; a French Lop eats several times what a dwarf breed does.
- Avoid muesli mixes, sugary treats and free-fed pellets, which drive obesity, selective feeding and dental disease.
- Offer fresh water in heavy ceramic bowls rather than small bottles, which cannot keep up with a giant's intake.
- Obesity is especially dangerous in this breed, because extra weight worsens sore hocks and stops the rabbit grooming its own rear, which invites flystrike in warm months.
Health
- Sore hocks (pododermatitis) are the headline risk, driven by the breed's weight pressing on thinly furred feet, so check the hocks weekly and keep flooring soft and dry.
- The lopped ears narrow the ear canal and trap wax, making otitis common, so regular checks for discharge, odour, scratching or head-tilt are equally non-negotiable.
- Gut stasis remains the classic rabbit emergency, and a French Lop that stops eating or passing droppings needs a vet the same day.
- The shortened lop skull predisposes to dental malocclusion, and giant breeds carry elevated risk of heart disease and arthritis in middle age.
- Vaccinate against RHDV2 everywhere, plus myxomatosis and RHDV1 where those vaccines are available (UK and Europe; no myxomatosis vaccine is licensed in the US), and neuter to prevent uterine cancer and ease bonding.
- Budget realistically: drug doses, boarding and surgery are all priced by body weight, so a giant costs giant vet money.
Temperament
- The French Lop is widely regarded as one of the calmest, most tolerant rabbit breeds, and a well-socialised adult is genuinely dog-like in its relaxed, people-oriented manner.
- That reputation is the main reason people seek the breed out.
- Calm does not mean carriable: a startled 6 kg rabbit kicks hard enough to fracture its own spine and to knock a child over, so interaction should happen at floor level and lifting should be rare, properly supported and done by adults.
- It suits respectful older children under supervision rather than toddlers.
- Like all rabbits it is social and should live with a bonded, neutered companion, ideally another large rabbit so neither partner is overwhelmed.
- A settled pair will sprawl, groom and follow their keeper around a room they treat as their own.
A good fit for
- Experienced keepers with giant-breed space
- Owners wanting a famously placid rabbit
- Homes able to fund giant-scale food and vet costs
- Those able to bond a large neutered pair
- Households offering calm, floor-level company
Common mistakes to avoid
- Standard hutches and cages are far too small
- Sore hocks from hard, wire or soiled flooring
- Lop ear canals prone to wax buildup and otitis
- Overheating above about 25°C (77°F)
- Powerful kicks can injure spine and handler
- Obesity blocking self-grooming, inviting flystrike
Is your enclosure big enough?
Is this urgent?
A rabbit that stops eating is an emergency, not a wait-and-see. Nothing else on this page is as time-critical.

Two rabbits are the minimum, and a bonded pair will also tell you when something is wrong — a rabbit sitting apart from its partner is worth a second look.
This is general guidance for a healthy adult, not a diagnosis. An exotics vet who knows your animal always overrides it — and the time to find one is before you need one.
Can a french lop rabbit eat that?
Hay first, greens second, everything else barely at all. A rabbit fed mostly pellets and treats is a rabbit with dental disease waiting to happen.
Never (23)
Rare treats (13)
Occasional (18)
Everyday foods (9)
That plant or food is not on our list. Do not offer it — a rabbit cannot vomit, so anything that goes in has to go all the way through. Check with an exotics vet.
A rabbit that has not eaten for 8 hours needs a vet, whatever the reason. Diet changes are the most common trigger for that, which is why new foods go in one at a time.
