Rabbits/tumor or not


Dear Dana,
hai Dana, I'm sanny.. would like to ask u a question according to my rabbit's jaw.. I had ever asked u a question before about his jaw last time.. the problem is getting worse.. I don't know whether it is a tumot or not.. coz it is getting huge like a big ball n very hard... my vet had given him a baytril but it doesn't work at all.. if it is tumor could it be removed? He is 4yrs old now... here I attached the pic of his jaw.. tqq dana

Dear Sany,

There was no picture attached.  

Without seeing this in person, I cannot make any sort of diagnosis.  The vet should be better able to tell you with an in-person exam, and the fact that the vet gave you Baytril suggests that this is a dental abscess/infection.  Please read:


If Baytril is not working, ask the vet about changing to long-acting Penicillin G Procaine/Benzathine injections every 48 hours.  Procaine and Benzathine are the only salts of penicillin or penicillin-related antibiotics considered safe for rabbits, and they must be given only via injection, NEVER orally.  No oral penicillins are safe for rabbits.  This particular drug can be very effective for head abscesses, but it can take several weeks of treatment for full resolution.  Not all bacteria are sensitive to penicillin, of course.  So the best course of action would be to try and get a good, representative sample from the capsule/fistula itself and have the pathogens identified:


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:

...it is an EMERGENCY.

Find a rabbit vet at www.rabbit.org/vet 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!
