Small mammals

Giant rabbits

Flemish Giant, French Lop, etc.

Most important: Lift only while sitting on the floor, with both arms. Spinal fracture is the number one accident

Basics

Lifespan
5-8 years (tend to live shorter lives than small breeds)
Weight
5-10 kg. Growth continues until about 18 months
Temperament
Easygoing and gentle. Slow, relaxed movements
Care difficulty
High (weight control, space, vet costs, safe handling)
Legal status
Covered by the Act on Welfare and Management of Animals. Lifelong care and proper husbandry are required
Key point
Lift only while sitting on the floor, with both arms. Spinal fracture is the number one accident

Ecology & traits

Body
Body length 50-80 cm, weight 5-10 kg. The skeleton is slender for the body weight, putting heavy strain on the heart and joints
Origin & range
Breeds enlarged in Europe for meat and fur. Many originate in Belgium and France
Wild habitat
Ancestors were burrowing grassland animals. Giant breeds were created under human care and do not exist in the wild
Activity & sleep
Crepuscular, but heavy-bodied and relatively inactive. Rests stretched out for long periods during the day
Social behavior & people
Gentle; many are unfazed by dogs and cats, but the weight difference means they can crush smaller cage-mates

Characteristic behaviors

Common illnesses: warning signs & prevention

Sore hocks (pododermatitis)

SignsHair loss and red swelling on the hocks, ulcers, bleeding, shifting weight from foot to foot, sitting hunched

PreventionAvoid wire or slatted floors; use thick mats. Control weight and trim nails. Keep floors dry and clean and check the foot pads weekly

Arthritis / spondylosis

SignsSluggish movement, no longer hopping, slow to stand, sitting with a hunched back, unable to groom itself

PreventionPrevent obesity and use non-slip flooring. Remove steps. From age 4, get checkups every 6 months with X-rays for early detection

Heart disease (cardiomyopathy)

SignsRapid breathing after slight exertion, open-mouth breathing, reluctance to exercise, fainting, lethargy

PreventionCommon in giant breeds. Avoid obesity and heat; from age 3, get an annual checkup including auscultation and cardiac ultrasound

Obesity

SignsLarge dewlap, spine cannot be felt, cecotropes left on the floor, unable to lick its own rear

PreventionHay-based diet with pellets at about 1% of body weight. Limit treats. Weigh and record monthly

GI stasis

SignsNot eating hay, droppings small, few or absent, bloated belly, teeth grinding, sitting motionless

PreventionGiant breeds eat a lot, so running out of hay is life-threatening. Always provide large amounts of hay. Heat, pain and stress are triggers

Urinary stones / bladder sludge

SignsCloudy white urine, straining in the litter box, bloody urine, urine-soiled rear, licking the genitals

PreventionCaused by lack of exercise and low water intake. Encourage drinking. Do not feed calcium-rich alfalfa to adults

Warning-sign checklist

Check once a day. If even one applies, contact an animal hospital early.

First aid for illness

Not eating or not passing droppings

Place hay and water in front of it and keep it quiet in a calm place. Do not force-feed or massage on your own judgment. If it has not eaten for 12 hours, see a vet immediately, even at night

Rapid breathing or open-mouth breathing

Move to a cool, quiet place; do not pick up or let it exercise. Keep it in a crouched position, not on its side, and place it in a carrier. Suspect heart disease or heatstroke and see a vet immediately

Red or bleeding hocks

Switch the floor to a thick towel or mat; do not wash the area, cover lightly with clean gauze. For bleeding or ulcers, see a vet the same day. Do not apply over-the-counter ointments on your own judgment

Cannot move or stand up

Do not force it to stand; support the body on a flat floor. Check whether it is urinating and defecating. If the hind legs do not move or drag, suspect a spinal fracture and see a vet immediately

Common injuries: prevention & first aid

Spinal fracture / dislocation

PreventionLift only while sitting on the floor, holding the chest and rear with both arms. Never lift while standing. Do not let it kick with its hind legs. If it struggles, put it on the floor at once

First aidIf the hind legs do not move, drag, or it does not urinate, do not handle it; lay it flat on a rigid board or in a carrier, keep it still, and see a vet immediately

Fall while being held

PreventionDo not let children or inexperienced people hold it. Guide it into a carrier instead of carrying it. Do not place it on raised surfaces

First aidDo not relax just because it moves right after the fall. Check gait, hind legs and urination; see a vet immediately if anything is wrong, and the same day even if nothing is

Broken nails / foot pad lacerations

PreventionBody weight loads the nails, so they break easily. Trim monthly. Keep the environment free of carpet or mesh that can snag nails

First aidPress with clean gauze for 5 minutes. Apply styptic powder or flour. For deep foot pad wounds or a nail torn out at the root, see a vet the same day

Dislocation / sprain on slippery floors

PreventionCover hardwood floors fully with mats. Avoid chase games that provoke sudden turns. Prevent obesity

First aidDo not touch the injured leg; rest it in a small carrier. If the leg is swollen or at an odd angle, see a vet the same day. If pain reduces appetite, watch for GI stasis

Zoonoses (diseases that can spread to people)

Pasteurellosis

RouteBites, scratches, contact with nasal discharge or saliva

PreventionBites from giant breeds are deep. Wash wounds under running water; see a doctor for swelling or fever

Dermatophytosis (ringworm)

RouteContact with the fur or skin of an infected rabbit

PreventionWear gloves when handling animals with hair loss or dandruff, and wash hands afterward

Cheyletiella (walking dandruff) mites

RouteContact with an infected rabbit, shared bedding

PreventionGiant breeds cannot groom themselves well, so mites multiply easily. See a vet for dandruff on the back

Tularemia

RouteContact with wild rabbits or ticks, raw meat, blood

PreventionDo not let it contact wild rabbits or ticks on outdoor walks. Do not crush ticks with bare hands

Husbandry: food, water, toys, nest, bedding

Food

  • Timothy hay in large amounts at all times. Never run out; daily volume should exceed the rabbit's body size
  • Pellets at about 1% of body weight, twice a day. More during growth
  • Vegetables about a handful per day. Fruit a few times a week, up to thumb size

Water

  • Heavy ceramic bowl, 300-500 ml or more per day. A bottle is not enough
  • In summer, place in 2 spots and change twice daily

Never feed

  • Onion family, potato sprouts, avocado, chocolate
  • Bread, rice, grains, human snacks (obesity, stasis)
  • Alfalfa for adults (stones, obesity)

Toys & play

  • Large chew wood, straw mats, burlap tunnels
  • Large cardboard box (60 cm or wider so the body fits)
  • Large paper bag stuffed with hay. Fabric mat for digging

Nest, bed & hideout

  • Wooden house at least 50 cm wide so the whole body fits
  • Steps and ledges no higher than 5-10 cm. No high platforms

Bedding & litter

  • Floor: slats fully covered with a thick mat or cushion mat
  • Litter box: a large tray for large dogs or cats, with wood pellets
  • Body weight compresses bedding, so change daily and keep dry

Housing: cage, exercise, temperature & humidity

Cage / housing material

Large-dog pen or cage. Wire or bare slatted floors are not acceptable

Size & space

At least 120 x 80 cm. Height 70 cm or more so it can stand upright

Layout

  • Large litter tray in a corner. Hay rack next to the litter box
  • Thick mat covering the entire floor to protect the foot pads
  • Water bowls in 2 spots. House with a wide entrance

Placement notes

  • Avoid direct sun and air-conditioner drafts; use a cool, north-facing room
  • Place directly on the floor with a step-free entrance. Wide door

Exercise, free-roam & walks

  • Daily free-roam time of 2 hours or more. Provide enough space to run
  • Floor fully covered with mats. Do not chase or stop it suddenly
  • Outdoors is not recommended due to heat and the danger of wild animals

Temperature & humidity

Temperature16-22°C. Risk of heatstroke above 25°C. The larger the body, the more heat-sensitive

Humidity40-60%. High humidity worsens foot pad ulcers and skin disease

Summer & winter

  • Summer: air conditioning 24 hours; place aluminum plates or large ice packs wrapped in towels
  • Winter: mats to block cold from the floor. Heat only part of the cage to avoid overheating

Grooming & protection from predators

Nail trimming

Monthly, one nail at a time with the rabbit sitting on the floor. Nails break easily under body weight; if it struggles, use 2 people or go to the vet

Brushing, skin & coat care

2-3 times a week, daily during molting. Giant breeds cannot reach their back or rear when grooming, so hairballs form easily

Other care

Wipe a soiled rear with a damp towel. Never bathe. Check the foot pads, the skin under the dewlap and inside the ears weekly

Protection from predators

  • Even if gentle, sharing a room with dogs or cats is dangerous. Lock the cage
  • Do not house with small rabbits or guinea pigs. It will crush them
  • In summer, watch for mosquitoes and fly strike. Keep the rear clean

Care precautions (accident prevention)

Foreign-body ingestion

Hairballs and carpet fibers cause stasis. Keep printed cardboard, plastic, cords and houseplants out of reach. Brush daily during molting

Being stepped on

Large body is less likely to be stepped on, but a trodden foot fractures easily. It burrows under sofas and bedding, so check before sitting or lying down

Getting pinched

Body or legs caught in doors. Secure doors with stoppers during free-roam time. Make the cage door wide enough for the body and check the whole body before closing

Falls

Falls while being held are the most common and lead directly to spinal fractures. Hold only briefly while sitting on the floor; never standing. Do not put it on sofas or beds

Escape

Pens get knocked over by its weight, so anchor them. Keep the front door and balcony closed. If it escapes, set out hay and its scented house and wait from dusk onward

How to safely release a bite

Never do this

  • Pull your hand away (giant-breed teeth tear deeply)
  • Hit, shout, or lift it off to pull it away

Safe release procedure

  1. Stop moving; do not force your hand out, stay still
  2. Stroke its back with your free hand to calm it
  3. Lower its body to the floor and wait for it to let go on its own
  4. Once it lets go, guide it to its house and leave it alone for a while

After the release

Wash with running water and soap, then disinfect. Deep wounds, swelling or fever carry a risk of Pasteurella; see a doctor

Emergency care manual

Go to an emergency vet now (life-threatening)

  • Not eating or not passing droppings for 12 hours or more
  • Open-mouth breathing, or rapid breathing even at rest
  • Hind legs not moving or dragging, not urinating
  • Hot ears and limp, seizures, fainting

See a vet the same day

  • Bleeding or ulcers on the hocks, odd sitting posture
  • Not hopping, slow to stand, sluggish
  • Bloody urine, cloudy urine, persistently soiled rear

What to tell the vet & what to bring

Weight, time of last meal, condition of droppings, room temperature, any falls while being held. Bring droppings and urine, and put hay in the carrier

Checking consciousness, breathing & heartbeat

  • Call its name and touch its body to check for a response
  • Check breathing by the rise and fall of the chest. Normal is about 30-60 per minute
  • Place a hand on the chest to check the heartbeat. Normal is about 130-250 per minute

Resuscitation steps

  1. Lay it on its side and remove any foreign matter from the mouth with a finger
  2. Squeeze the thickest part of the chest between both hands, 100-120 compressions per minute
  3. Compress to one third of the chest depth. Do not twist the spine
  4. Cover the nose with your mouth and give 2 gentle breaths after every 30 compressions

Stopping bleeding

  • Press firmly with clean gauze for 5 minutes. Do not lift to check
  • For nail or foot pad bleeding, press on styptic powder or flour
  • Ear bleeding looks heavy but stops with pressure. If not, see a vet

Transport

  • Line a large-dog carrier with a towel and keep the body flat. Cover to darken
  • Summer: ice pack beside it; winter: hand warmer on the outside. Carry with 2 people
