Why is my old dog having diarrhea with mucus after dental surgery?
I am sorry to hear about your recent troubles with Nora's health. I have certainly heard of lots of different side effects long term from any sort of anesthetic procedure, the most common actually being changes to behavior. I have definitely also heard of animals that have come blind or deaf from anesthetic (though usually it is temporarily) episodes. While I can not say for sure what has happened in this case, I would definitely want to completely rule out the possibility of a coincidence first since we are dealing with such an elderly patient. I imagine that with an older patient, preoperative blood work was obtained and analyzed prior to placing her under anesthesia. If this was completely normal, I would definitely recommend having some x-rays and ultrasound imagine procured to rule out the presence of any sort of malignant process or signs of organ failure. If you are able to do this with at least a relative amount of certainty, this still doesn't resolve the issue. I would considering adding more fiber to the diet and a probiotic to see if this helps solidify the fecal material while investigating the cause.
I don't want to sound grim, but at nearly 16 years of age there are a number of sinister things within the body that could be responsible for Nora's diarrhea unfortunately. The anesthetic event could have certainly compromised the immune system in such a way to make her susceptible to something that may have been lying in wait or brewing slowly.
I hope you are able to figure things out soon and get back on track. Best of luck and let me know if there is anything else I can do for you.
