Rabbits/Pneumonia/Collapsed Lung


My rabbit, Pumpkin, has been diagnosed with pneumonia. He has been on Enroflaxin and Lasix since April 25. His lungs were getting better and he was not coughing or sneezing as much. He had a barium swallow because they though he might have a diaphragmatic hernia. That came back negative. Today I took him back because it looked like he was breathing a little harder over the weekend and they put him on oxygen when he got there just to be safe. She has put him on Azithromycin,Trimthoprim/Sulfa, and has him continuing the Lasix. She said she did an ultrasound and his right lung is clear but the left lung looks solid so she thinks he may have a collapsed lung. When we were bringing him home he started to panic and he opened his mouth like he couldn't breath and kind of fell over. When we got him in the house he started to calm down and then he was acting normal. He always acts normal in every way except the sneezing and coughing and recently the hard breathing but that hasn't stopped him from enjoying himself. They also did an aspiration of the fluid and she said it didn't show any certain kind of organism. I'm not really sure what I'm asking. I just extremely worried and wonder if you have any other ideas or if this sounds right. I also don't want to keep taking him to the vet all the time because it really stresses him out. What if it is a collapsed lung? What can we do? Is the pneumonia going to get better r will he have it the rest o his life? He also has malocclusion and once a year has to get his back teeth trimmed and I won't do that if he is having difficulty breathing. I volunteer at Heartland Rabbit Rescue in OKC and the director gave me your name. I appreciate your help.

Dear Christine,

Treatment for a collapsed lung in a rabbit will not be very different from treatment for a collapsed lung in any other species.

If the condition is not severe, it may resolve on its own as your bunny recovers from the pneumonia with proper medication. But if bun appears to be having difficulty breathing, please ask the vet about nebulization with medications to open her airways and help mucus mobilize so it can be coughed up and swallowed.  It might be worth asking about supplemental oxygen you can administer at home, too.

I hope this helps.

I've lived with companion rabbits for more than 35 years, and consider them members of my family. I can answer any questions about the biology and health of rabbits, from the commonplace to the unusual. But please note:

RULE #1:

Find a rabbit vet at for immediate help, and don't risk your bunny's life by spending time asking questions online! If you can't get in touch with your vet, read these Emergency Sick Bunny Instructions.

If you have found a wild baby rabbit, please read these EMERGENCY INSTRUCTIONS FOR WILD BABY RABBITS and then use this link to FIND A LOCAL WILDLIFE REHABILITATOR who can give you the right advice.

RULE #2:
Help me help you! Please make your subject line informative if you have an urgent question. then LET ME KNOW IN THE SUBJECT LINE so I can give your question highest priority over non-urgent questions. If you don't do this, then I can't guarantee timely assistance!
