When I got my bun neutered, the vet was almost unable to give him pain meds. They would hold him and stick the syringe behind his teeth, and my rabbit would struggle so much his wound would ‘ooze’. They actually told me when I came to take him home that giving him the pain meds would probably cause him more stress than not doing so…needless to say, this stressed ME out considerably.
Well, when we got home I tried a different tactic than restraining him. I gave him a tiny piece of dried papaya ( he loves it), another tiny piece, then filled up the syringe with the meds and smeared some papaya near but not on the opening. I put the syringe in front of my bun’s face, he bit onto it, and I slowly squirted the meds into his mouth. SO easy! After that, all I needed to do would lower the syringe into his cage and he would run and bite it, allowing me to squirt the meds in. Just had to be careful not to administer them too quickly, or the rabbit could choke on the fluid.
