This reminds me a bit of my own bun. Is your rabbit vet rabbit savvy?

My bun had to be hospitalized f + 2 days. The resident vet managed to get us a consultation with a rabbit savvy vet, thank goodness. The rabbit savvy vet said there was a partial obstruction in the small intestine. Treatment was IV fluids (drip) and painkillers (novalgin).

We got to tske him home again on a regimen of watery critical care (syringed), meloxicam (1.5 mg per kilo body weight once every 12 hours) plus Pepcid famotidine). No gut motility drugs since that’s contra-indicated when there’s a GI obstruction.

Ask them if iv fluid drip could be an option. In some countries vets can show pet owners how to give subcutaneous fluids at home. In some countries, this is prohibited by law.

Lactulose to increase the volume of the intestinal content is sometimes prescribed. If no obstruction is suspected, a gut motility drug like metoclopramide could potentially be an option.

Pain control is always of the essence when it comes to buns.

I think there was a miscommunication in the thread above. Bam was saying that motility meds shouldn’t be used if there is a blockage, but they are used for stasis. Sometimes a combination of multiple meds is needed . The two main motility meds are metaclopromide and cisapride, they affect different parts of the gut. It sounds like your bun is getting treatment, but may need dif meds or just more time and gentle supportive nursing care. I would resist the urge to do aggressive tests or treatments, especially if the vet is not 100% rabbit savvy. Sometimes the treatment is perfect but the bun needs more time to respond.

Encouraging movement in cases like this can help too. One of my bridge buns Bun Jovi was at the vets with stasis and he wouldn’t poop for two days until they put him in one of the exam rooms to run around. Then he finally pooped all over the place!
