The Holland Lop is a breed of rabbit originating in the Netherlands. The breed was recognized by the Netherlands' Governing Rabbit Council in 1964 and the American Rabbit Breeders' Association in 1979. They are popular house pets, and are very popular and competitive for show. They are also known for their sweet temperament and nonaggressive behavior, though they retain a certain doglike tenacity.
The Holland Lop is often thought of as a highly calm and gentle pet rabbit, and this is usually true. This breed tends to be very kind and quiet, though they need exercise like most rabbits. The Holland Lop makes an excellent pet for children or families, and especially as a first rabbit. They are very easy to care for and have a sweet personality that makes them wonderful pets.
The Holland Lop rabbit breed was developed in the Netherlands by a man named Adrian DeCock. He crossed a French Lop to a Netherland Dwarf, giving birth to the first ancestor of the Holland Lop. The breed came to the USA in 1975 and was instantly popular. They were soon recognized by the ARBA and are still incredibly popular today. 
Diet And Feeding
The Holland Lop rabbit should be fed daily with good quality pellets, fresh vegetables and unlimited grass or timothy hay, as well as fresh water. Pellets should be fed at 1/4 cup to 1/2 cup per 6 pounds of body weight.  Rabbits enjoy many different types of fresh vegetables, such as romaine lettuce, endives, parsley, coriander, dill, fennel and arugula, as well as carrots. Fresh leafy vegetables should be fed at a rate of at least 1 packed cup per 2 pounds of body a day. Leafy greens high in oxalic acid, such as parsley and spinach, should not be fed every day. Non-leafy vegetables such as carrots or peppers should be fed in much smaller quantities, about 1 tablespoon per 2 pound of body weight per day.  Alfalfa hay or alfalfa based pellets should only be fed to juvenile rabbits under 1 year. Treats from pet supplies stores are often not particularly safe for rabbits to ingest. They often are high in sugar or fat, or contain foods that rabbits cannot digest.  Rabbits can experience gastrointestinal upsets or diarrhea from foods their bodies are not used to. To avoid this, slowly introduce new foods one at a time, starting with small quantities and gradually increasing to larger portions over several days. Severe diarrhea can be fatal between 24-48 hours, any rabbit showing signs of this needs immediate medical care.
