If you suspect pneumonia in your rabbit you must take it to the veterinarian immediately, as untreated cases can become fatal.
If the rabbit is suffering from anorexia, fever, weight loss, or lethargy, hospitalization may be required; electrolyte and fluid therapy is also helpful for maintaining and hydrating the rabbit. Your veterinarian will prescribe antimicrobial, antiviral, antifungal, or antibiotics, depending on the specific organism and which prescribed chemical is needed to destroy the infection. If the chest or lungs are congested, oxygen (nebulization) therapy may be used to clear the rabbit's airways.
The rabbit's activity should be restricted, whether or not it needs hospitalization. Also, it is imperative that you encourage your rabbit to eat during treatment and following treatment. In addition to its pellet diet, offer a large selection of fresh, moistened greens such as cilantro, romaine lettuce, parsley, and carrot tops. If the rabbit is refusing to eat, a syringe of gruel may be necessary. Your veterinarian will advise you on the best way to feed your rabbit, and which foods are best under the specific circumstances.
