I’m glad you were able to post. For background, I’m pretty experienced with teeth trimmings and sneezing, as Wick is less than a year old and has had three teeth trimmings and had a 3mo upper respiratory infection because, why not be complicated Wick… So to this extent, I’m familiar with what recovery should usually look like, though conditions or consequences of your rabbit being older, I can only make educated guesses.

1) Bladder sludge: This may be a separate issue entirely. Bladder sludge is typically caused by diet if I remember correctly. Excess calcium and not enough fiber can cause it. You said it “fixed itself” in the past, which probably came naturally from her eating hay and the hay fibers cleaning it out. What was her diet leading up to this? Would you say there may have accidentally been excess calcium or too little fiber? This also could have been a result of the period when you were not able to pay too much attention and the sludge developed during that window of malnutrition.

2) Coughing/Sneezing – Antibiotics if it is the suspected dormant-bacteria we messaged about. If you see she has too much discharge that she cannot clean herself, get a very soft, clean towel, damp it a little, and help wipe any discharge away. Monitor and inform your vet if the sneezing and discharge gets worse, as that means the treatment course is not working. With treating bacterial infections, it’s sometimes a trial-and-error system, where you need to find which antibiotic hits the strain your rabbit has. If one doesn’t work, try another.

3) Recovery from the teeth trimming – Recovery from teeth trimming is pretty simple. Any complications should really only warrant the metacam for pain management. I am not familiar with the other 2 medications you were given (presumably for the ulcer), so I wonder if her inactivity is a result of those medication. After a metacam dose, Wick is quite tired, so I cannot imagine the result of a cocktail of 3. Wick did not need pain medication following his first two teeth trimmings, bouncing back within the hour of coming home (eating fine). The third teeth trimming triggered a tooth infection he has, which he’s currently being treated for. Has your vet re-examined her teeth since the operation? It was not until I scheduled a follow-up appt (which Wick’s vet found unusual since his other two trimmings, I hadn’t expressed concern) that I had Wick’s vet look at his teeth, Wick’s vet noticed he was still producing excess saliva to compensate for discomfort. That’s when we thought about a tooth infection, and now Wick is getting treatment for that and is acting much more himself.

Honestly, I would say find another, valid -rabbit experienced- vet and consult. I’m weary that you were given the 3 medications at once. Maybe concurrent treatment is really affecting her. I see it as 1) treat the cause of the continual tooth ache, as it should not be persisting for so long, 2) then treat the sneezes, and all the while 3) continue to feed CC, hay, and pellets to maintain nutrition consumption. I’m not a professional though, and again, your rabbit is older.

***ALSO! From a cursory google search, I think metoclopramide is a probiotic…? If someone can give a solid statement on that, that’d be great. If it’s not, I think you should inquire to get a probiotic powder, which will help replenish gut-bacteria that’s lost when your rabbit takes antibiotics.

And another also— I actually went through this with Wick over this past weekend. His poops were very small because he’s only eating the bits of hay he’s comfortable eating due to his dental discomfort (tooth infection). The ‘protocol’ I take when this happens with Wick is a continuous cycling of small, fresh hay presentations. I put a small handful of fresh, out-of-the-bag hay in his boxes. He goes through, eats what he wants, then I leave it there for an hour or so. After a time window, I take any re-usable hay, toss it in the hay box for use after he’s recovered, and replace the hay with another small fresh, out-of-the-bag hay handful. Rinse and repeat continuously. This morning, Wick’s poops were bigger than his average, so it worked really well. His hay box is super full now, but I don’t feel wasteful because once he gets better, I’ll only present hay from the hay box, rather than fresh from the bag.

Orchard hay may do well for her as well right now, since it’s softer.

Metoclopromide is a gut motility stimulator. Marshmallow was on it during his stasis episode, though he was switched to cisapride when metoclopromide wasn’t really doing the trick.

Have you had your vet give her sub-q fluids? That can help with dehydration, get the gut moving again and possibly help with some of the sludge which is more likely an age related thing that could be due to many things even arthritis.
