Holland Lop Rabbit

Is a Holland Lop rabbit right for you?

With its drooping ears and compact, rounded body, the Holland Lop is one of the most popular small rabbit breeds; the breed standard sets the maximum at about 1.8 kg (4 lb). It is usually described as friendly and playful. Two things to know: rabbits are not rodents but lagomorphs (they carry a second pair of small peg teeth behind the upper incisors and digest food differently), and those appealing lop ears are a trait that comes with a health cost.

The most critical point: a Royal Veterinary College study of a rescue population found ear and dental problems were more common in lop-eared rabbits than in erect-eared ones. If you choose this breed, treat regular ear and tooth checks as part of routine care.

Before you adopt

Some babies sold as "mini lops" or "dwarf lops" are crossbreeds and can grow larger than expected. Seeing the parents gives the best idea of adult size. Lop-eared adults are also common in rescues, and their personalities are already known.

A baby should be at least 8 weeks old. Check:

• Inside the ears: no bad smell, brown wax build-up, crusts or discharge. Head shaking or ear scratching is a warning.
• Teeth: the upper incisors should close just in front of the lower ones; protruding lower teeth or teeth meeting end to end are a problem.
• Eyes and nose: no discharge, watering or sneezing.
• Rear end: clean and dry.

A rabbit is a 10-year commitment. Find a rabbit-savvy vet before you adopt.

Social needs and neutering

Rabbits are group animals; the most reliable pairing is a neutered male with a neutered female. A guinea pig is not a suitable companion. Neutering reduces urine marking and aggression, makes litter training easier and removes the risk of uterine cancer, which is common in unspayed females. Discuss timing with your vet; females can become pregnant at four months.

Living space

A cage alone is not enough. The Rabbit Welfare Association recommends a single connected area of at least 3 m x 2 m of floor and 1 m high for two rabbits. Indoors, that means a rabbit-proofed room or a large pen.

• Cover cables with protectors; rabbits chew them.
• Lay washable rugs or non-slip mats over slippery floors.
• Provide a hiding house with two entrances.
• Fill the litter tray with paper pellet litter and put hay right next to it. Do not use pine or cedar shavings or cat litter.

Temperature: around 18-20 °C is ideal; the risk rises quickly as it gets hotter. In hot summers plan for an air-conditioned or naturally cool room; a frozen water bottle wrapped in a towel and a cool ceramic tile help.

Feeding: the hay rule

The foundation of dental and gut health is unlimited hay. Dental problems are common in this breed, so never compromise on hay.

• Hay (most of the diet): timothy or meadow grass hay, fresh and unlimited every day. Alfalfa hay is only for growing youngsters.
• Pellets (small amount): for adults about a quarter cup per 2.25 kg; for a 1.5-1.8 kg Holland Lop roughly 2-3 tablespoons. Avoid grain-heavy, colourful mixes.
• Greens (one or two handfuls daily): leaf lettuce, rocket, dill, coriander, mint, bell pepper. Limit high-calcium greens such as parsley and kale.
• Fruit and carrot: as treats, in small pieces, a few times a week.
• Water: a shallow, heavy bowl, fresh every day.

Do not give: bread, biscuits, cereals, nuts, chocolate, avocado, onion, potato or human food.

Health and lifespan

Average lifespan is 7-10 years; some individuals live longer with good care.

Problems that stand out in the breed:

• Outer ear infection (otitis): in a lop ear the ear canal folds and narrows at its base, wax builds up and bacteria and yeast multiply. Signs: head shaking, ear scratching, bad smell, swelling at the base of the ear, pain when touched. If it spreads to the middle ear it can cause head tilt and loss of balance. Rabbits often hide pain, so weekly checks are essential.
• Dental malocclusion: more common in dwarf and lop-eared breeds. Dropping food, drooling, swelling on the jaw or under the eye and weight loss are signs. Teeth need correcting under anaesthesia, and this may need repeating.
• GI stasis: stops eating, droppings get smaller or stop, quiet and bloated. Not eating or passing droppings for 12 hours is an emergency. It is often triggered by dental pain, stress or a low-fibre diet.
• Heatstroke: red, hot ears, fast or open-mouth breathing, lethargy. Move to a cool room, wet the ears with cool water and call your vet. Do not wrap in a wet towel or cuddle.
• Sore hocks: develop on hard, slippery floors and in overweight rabbits.
• Uterine cancer: common in unspayed females.

Vaccination: myxomatosis, RHDV1 and RHDV2 are usually fatal and can reach indoor rabbits via flies, fleas, clothing and shoes. Vaccination can start from about 5 weeks and is repeated yearly. Ask your vet which vaccines are available where you live.

Ear cleaning: you can wipe wax from the visible part of the ear with a damp cotton pad, but never push a bud into the canal. Use ear drops and antibiotics only on veterinary prescription; some antibiotics cause fatal gut disruption in rabbits.

Handling and communication

Holland Lops usually bond quickly with people but, like most rabbits, dislike being lifted.

1. Spend time on the floor. Sit down, let it come to you and hand-feed greens.
2. Stroke the head and forehead. The base of the ears can be sensitive; never pull the ears.
3. When lifting, one hand goes under the chest and the other supports the hindquarters. Never lift by the ears or scruff; a kick can break the spine.
4. Grooming: brush weekly and daily during a moult. Trim nails every 1-2 months. Check ears weekly. Do not bathe in water.

Body language: jumping and twisting in the air is joy, thumping a hind foot is alarm, and flopping onto its side is deep relaxation. Sitting hunched and loud tooth grinding can be signs of pain.

Enrichment

1. Digging box: a cardboard box filled with paper or hay.
2. Tunnels and low platforms: because of its stocky build, prefer low steps to high jumps.
3. Foraging: hide pellets in the hay.
4. Chewing: willow, apple branches, cardboard.
5. Exercise: access to a large area in the morning and evening.

History and origins

The Holland Lop was created by Dutch breeder Adriaan de Cock of Tilburg. His aim was to combine the lop ears of the large French Lop with the small size of the Netherland Dwarf. The first crosses, begun in 1949, did not produce lop ears; English Lop blood was added in the following years to achieve the desired type. After recognition in the Netherlands the breed reached the United States and was accepted by ARBA in 1979.

Lop ears do not occur in wild rabbits; the trait was fixed by human selection. Like all domestic rabbits, the Holland Lop descends from the European wild rabbit (Oryctolagus cuniculus), which lives in colonies in burrow systems.
