Overview

What is this animal?

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.

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

Enclosure

Minimum 60,000 cm² of floor (9,300 sq in) — for the pair · 300 × 200 cm

Cannot be kept alone. The minimum is 2, and the space above is for that group.

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.

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.

Go now

Not eating, or not producing droppingsCall an exotics vet. Some sources treat 3 to 4 hours as the point to start worrying and 12 hours as an outright emergency; do not wait to find out which camp is right for your rabbit. Gut stasis can become life-threatening within 12 to 24 hours, and every hour of delay makes it harder to reverse.

8 hours

Hunched with the belly pressed to the floorGo now. A rabbit in this posture is in significant pain.

Now

Loud teeth grindingGo now. Distinct from the soft purr of a content rabbit. This is a pain signal.

Now

Hard, bloated abdomenGo now. Do not force-feed and do not massage. Bloat may need decompression rather than gut motility drugs, and the two treatments conflict.

Now

Maggots or fly eggs near the rearGo now. Flystrike. Check the rear twice a day in warm weather, every day, for every rabbit.

Now

Cannot cope with heat — panting, wet nose, lying flat and unresponsiveMove to shade, offer a wrapped cool pack, wet the ears, and go. Rabbits cannot pant effectively to cool themselves; distress starts around 28C and rises steeply.

Head tilt, or eyes flicking side to sideBook today. Outcomes are far better with early treatment.

Today

Weight down 50 g or more since last weekCall today with the weight history. Fur hides body condition completely. The scale sees it first.

Today

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.

Rare treats (13)

AppleSugar. The seeds contain a cyanogenic compound and must be removed. A thin slice, once or twice a week. Never the seeds or core.

rare treat

BananaVery high in sugar and starch, and most animals will overeat it given the chance. A slice the width of a fingernail, rarely.

rare treat

BlueberrySugar, but a small portion size makes it easy to control. One or two berries, twice a week.

rare treat

Brussels sproutsHighly gas-forming. Half a sprout, rarely.

rare treat

CarrotSold as the archetypal rabbit food and it is nothing of the kind: carrot is a root vegetable with a high sugar content. The leafy tops, by contrast, are an excellent green. A thin slice as a treat. The tops can be fed freely.

rare treat

CauliflowerOne of the most gas-forming brassicas. A very small piece, occasionally.

rare treat

GrapesVery high in sugar. Halve them, because a whole grape is a choking hazard. One halved grape, rarely.

rare treat

OrangeAcidic and sugary; can irritate the mouth and gut. A tiny segment, rarely if at all.

rare treat

PearSugar. Remove the seeds. A thin slice occasionally.

rare treat

PeasHigh in starch and sugar. The pods and leaves are better than the peas. A few pods occasionally.

rare treat

StrawberrySugar, though lower than most fruit. The leaves are actually the better part. Half a small berry, once or twice a week.

rare treat

TomatoThe ripe flesh is safe in small amounts. The leaves, stems and any green fruit contain solanine and must never be offered. A small piece of ripe flesh, occasionally. Never the plant.

rare treat

WatermelonSugar and a very high water content, which together can loosen the gut. Remove the seeds. A small cube in hot weather, rarely.

BroccoliNutritious but a notable gas producer. Leaves and stalk are better tolerated than the florets. A small floret or a piece of stalk, twice a week.

occasional

CabbageA brassica. Gas-forming in quantity, and goitrogenic with heavy long-term feeding. A small piece, once or twice a week.

occasional

CelerySafe and well liked. Cut across the stalk so the long fibres cannot catch. A short piece, cut into segments.

occasional

ChardSame oxalate issue as spinach. A small leaf, occasionally.

occasional

CourgetteSafe and mild. Serve raw. A few slices a few times a week.

occasional

CucumberSafe, but it is mostly water with very little in it. Useful for hydration in warm weather, poor as a staple. A few slices.

occasional

DillSafe in rotation. A few fronds.

occasional

Green beansSafe cooked or raw in small amounts. Gas-forming in quantity. One or two, occasionally.

occasional

KaleHigh in calcium and a mild goitrogen. Genuinely nutritious, but not the everyday green it is often sold as. A leaf or two, two or three times a week.

occasional

MintSafe in small amounts; strongly flavoured and not every animal wants it. A leaf or two.

occasional

ParsleyNutritious but relatively high in calcium. Fine in rotation, not as the whole green portion. A few sprigs, a few times a week.

occasional

PelletsA uniform pelleted nugget, not a muesli mix. Muesli lets a rabbit pick out the sweet bits and leave the fibre, which is how dental disease starts. An eggcup per rabbit per day, no more.

occasional

PumpkinSafe and well tolerated in small amounts. A small cube occasionally.

occasional

RocketPeppery and well tolerated in rotation. A small handful, a few times a week.

occasional

SpinachHigh in oxalates, which bind calcium and contribute to bladder sludge and stones in animals prone to them. A single small leaf, no more than once or twice a week.

occasional

WatercressNutritious, strongly flavoured, high in calcium. A small handful occasionally.

Everyday foods (9)

Bell pepperOne of the best everyday vegetables here: high in vitamin C, low in sugar, no oxalate problem. Remove the seeds and stalk. A few strips daily.

everyday food

Bramble leavesBlackberry leaves are excellent forage and rabbits take them readily. A few leaves daily.

everyday food

Carrot topsThe leaves are a proper green and much better food than the root. A handful as part of the daily greens.

everyday food

CorianderWell tolerated, aromatic, and most animals take it readily. Part of a daily mixed handful.

everyday food

Dandelion leavesOne of the best greens available, and free. Pick well away from roadsides and anywhere that may have been sprayed. A generous handful daily.

everyday food

GrassFresh growing grass is excellent. Lawn clippings are not: they ferment in the bag and cause severe gut upset. As much as they will graze. Never mown clippings.

everyday food

Grass hayShould be about 80 percent of what this animal eats, available at all times. It is what wears the teeth down and what keeps the gut moving. Unlimited, always.

everyday food

PlantainA common lawn weed and one of the better forage plants. A handful daily.

everyday food

Romaine lettuceDark leafy lettuce with real nutritional content and a good water balance. A generous handful daily as part of a mixed selection.

everyday food

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.
