Some rabbits are very small. 

Other rabbits are small in a different way. They do not have the dwarfing gene. Instead, people use selective breeding. This is a way to make animals smaller over many years. They pick the smallest rabbits to make new babies. The Polish and Britannia Petite breeds use this way. 
Dwarf rabbits are very small animals. People use this name in a few ways. Sometimes it means a rabbit with a special dwarfing gene. Other times, it just means any small breed of pet rabbit. 

There are two main ways a rabbit becomes small. One way is through a genetic condition. A gene is a part of a living thing that passes traits to babies. The dwarfing gene, or dw, makes the rabbit stay small. 
Some small rabbits show signs of neoteny. Neoteny is when an adult animal keeps traits that babies usually have. This can make people feel attracted to these small animals. The Netherland Dwarf is a great example of this. It has a very short neck. It also has a rounded face. These are parts of neoteny that help make it look unique. 
Many different breeds are recognized by groups like the ARBA. The American Rabbit Breeders Association (ARBA) has rules for rabbit weights. The Netherland Dwarf is the smallest domestic breed. It weighs between 1 and 2.5 pounds. 

There are many types of small rabbits to learn about. Some have erect ears that stand up straight. Other breeds have lop ears that hang down. The Teddy Dwarf and the Dwarf Hotot are small breeds. The Jersey Wooly and the Lionhead are others. Even wild rabbits can be small. The Marsh rabbit is a small wild species. It is an excellent swimmer and weighs about 2.5 pounds. 
The term dwarf rabbit can have several different meanings. Formally, it refers to a rabbit that carries a specific dwarfing gene. Informally, people use the term to describe any small breed of domestic rabbit. It is also used colloquially to mean any small rabbit. 
There are two primary ways a rabbit achieves a small stature. The first way involves the dwarfing gene, which is written as dw. This gene causes the rabbit to be small. The second way is through a process called selective breeding. In this process, breeders choose the smallest rabbits to produce the next generation. This is also called dwarfing. 
Many small rabbit breeds show signs of neoteny. Neoteny is when an adult animal keeps physical traits that are usually only seen in babies. This trait may be why people find dwarf animals so attractive. 
Different organizations set the rules for what counts as a small breed. The American Rabbit Breeders Association, or ARBA, recognizes many types. The Netherland Dwarf is the smallest domestic breed. The ARBA accepts a weight range of 1 to 2.5 pounds for this breed. 
There are many recognized breeds with different physical features. Some breeds have erect ears, which means their ears stand up straight. Examples include the Teddy Dwarf and the Polish. 



Other interesting breeds exist with unique appearances. The Lionhead is a breed that people recognize. 

Understanding dwarf rabbits connects to the study of genetics and biology. It shows how genes like the dw gene change how an animal grows. It also shows how selective breeding can change a species over many generations.
