I’m sorry you didn’t get to see the vet. cecotropes is a really great sign. Have you seen any fecal poop (the round dry poops)?
For tummy x-rays, concious x-rays would be the preferred way. I was just curious as to why they ruled this a blockage and not “just” stasis (stasis meaning insufficient movement of the intestines. Treatment protocol differs. For stasis due to a slowdown of the gut you can give motility meds (metclopramide for example) to help start up the gut again. For a blockage you can’t risk that.
For a blockag,e the meds you’ve been given are adequate. If he’s willing to take water from the syringe that would be good – fluids are really important, both oral and sub Q. Be very careful though so he doesn’t get water or CC in the wrong throat (aspiration). It is very stressful to syringe feed a bun, they dont normally appreciate it.It gets earier with practice, luckily. Buns tend to forgive and forget once they’re well again.
Sitting with the head up can mean difficulty breathing. This can mean there’s an airway infection. An airway infection can follow after an aspiration event or it could be the very cause of this whole thing. I’d like a vet to listen to his lungs. If there is a breathing problem antibiotics would probably be needed.
