The Netherland Dwarf is the smallest of the 45 breeds recognized by the American Rabbit Breeders Association, weighing in at a mere 2 lbs when fully grown.
Feeding
The digestive system of a Netherland Dwarf is sensitive, even by bunny standards. A constant supply of fresh water is a must; rabbits cannot absorb water from their food. A gravity water bottle attached to the inside of their cage will prevent spills and contamination. Also, a constant supply of timothy hay provides a great source of fiber and allows for all day nibbling. Alfalfa could be used but is higher in calcium and protein and lower in fiber. Too much calcium can lead to serious kidney and bladder problems. About 250 mg a day is sufficient for a mature Netherland Dwarf.
