The Smallest Rabbit in World?
While Simon and Darius are the two biggest rabbits in the world, there is no official record for the smallest rabbit. However, the title of “World’s Smallest Rabbit” is often given to the Netherland Dwarf Rabbit. This breed typically only grows to be about 20 cm (seven inches) in length and 0.91 kg (two pounds) in weight.
What factors contribute to a Rabbits’ Size?
There are a few factors that can contribute to a rabbit’s size. For example, the diet of a rabbit can play a role in how big it gets. A healthy diet of hay, vegetables, and pellets will help a rabbit to reach its full potential size.

Additionally, the breed of rabbit also plays a role in how big it can get. As we saw with the Flemish Giant Rabbit, some breeds are just naturally larger than others. Lastly, the environment in which a rabbit lives can also impact its size. For example, if a rabbit is kept in a small cage, it may not have enough room to grow to its full potential size.
Genetics
Rabbits have been selectively bred to produce large individuals for meat and fur production, as well as small individuals for pets.
Large Rabbits are bred by crossing large individuals of different breeds. The Flemish Giant is a cross between the French Lop and the Belgian Hare.
The German Lop was bred by crossing the English Lop and the German Hare.
Some small rabbits are bred by selecting for dwarfism genes. The Netherland Dwarf is an example of a breed with these genes.
Dwarfism in rabbits can also be caused by a virus, which causes stunted growth and skeletal deformities. This condition is called viral hemorrhagic disease, or VHD.
Breed
One of the largest factors that influence the size of a rabbit is the breed. Some breeds, like the Flemish Giant, are naturally larger than others. Other breeds have been bred to be smaller, like the Netherland Dwarf. The table below shows the average weight and height of some common rabbit breeds.

Diet
A rabbit’s diet will also play a role in the size of your rabbit when it matures. A healthy diet for a rabbit includes hay, fresh vegetables, and pellets.
A diet that is lacking in nutrients can lead to stunted growth or even health problems later on in life.
For example, a diet that is too high in sugar can cause obesity and other health problems.
Environment
The environment in which your rabbit lives will also impact its size. If a rabbit is kept in a small cage, it may not have enough room to grow to its full potential size. Additionally, if a rabbit does not have access to fresh hay or vegetables, it may also be stunted in growth.
It is important to make sure that your rabbit has enough space to exercise and play. A good rule of thumb is to provide at least four times the size of your rabbit in square footage.
Rabbits are social animals, so it is also important to provide them with a companion. Otherwise, they may become anxious and stressed, which can impact their health and growth.
Health
A rabbit’s health can also play a role in a rabbit’s size by stunting growth. If a rabbit is sick or has an illness, it may not grow to its full potential size.
Additionally, if a rabbit has parasites, this can also lead to health problems and stunted growth.
Rabbits are susceptible to a number of diseases and health problems. Some of these diseases can be deadly, so it is important to take your rabbit to the vet for regular check-ups.
VHD
As we mentioned before, one disease that can cause dwarfism in rabbits is called viral hemorrhagic disease (VHD). This disease is caused by a virus and leads to stunted growth and skeletal deformities. VHD is deadly in rabbits and there is no known cure.
However, there are vaccines available that can help to protect your rabbit from this disease.

Pregnant Does
Another health issue that can lead to stunted growth is pregnancy in does. If a doe becomes pregnant, she may not have enough resources to support both herself and her litter. This can lead to the development of health problems in both the doe and her litter. Additionally, the litter may be born premature or smaller than average.
Climate
Climate can play a role by impacting the availability of food and water. For example, in areas with a lot of rainfall, there may be more vegetation available for rabbits to eat.
On the other hand, in arid climates, there may be less vegetation available, which can impact a rabbit’s growth.
Finally
As we have seen, there are a number of factors that play a role in how big rabbits can get. These include diet, breed, environment, and health. By understanding these factors, you can provide your rabbit with the best possible care to help them reach their full potential size!
