Thank you for clarifying.
First, I am glad to see that the urine situation is not a change for her. The reason is because while we do need to question why her urinary concentration is so poor, we wouldn't assume it is related to her current issues. So, we can put that aside for the moment, though it's be worth having her vet test a urine sample when they do see her (or if you choose to submit a sample to their office). Otherwise, I would just note that if you do want to switch from Tylenol to ASA, remember you need to give her at least 48 hours off both before switching.
Those all aside, I am glad to hear that she is eating and more settled, though the gurgly GI is highly suggestive of nausea still lurking here. In regards ***** ***** to approach this, I have to say that if we do not have diarrhea, then Pepto Bismol should be avoided as it could cause her constipation. As well, as there are limited studies on the safety and dosing range of oral Zofran on pigs, I would instead suggest treating her with an antacid like Zantac/ranitidine ( 1.5 milligram per kilogram of body weight every 12 hours) or Pepcid/Famotidine
(2.5 milligrams per kilogram of her body weight every 12 hours). These can reduce nausea, help with the gurgling and also can help counter act any GI irritation or damage caused when using non-steroidal anti-inflammatories. So, this would be a better option with its know safety spectrum but also wider effects.
Overall, I agree that this situation is not likely to be related to the lameness
. It sounds like her GI upset was secondary to over indulgence but if there is nausea remaining and she is on an anti-inflammatory for lameness, then the use of an antacid would be ideal here to try to reduce her nausea while protecting her stomach
. And if that lameness doesn't settle, then we'd want to have her vet check this (to ensure she has not damaged a tendon, etc) but also consider having a urine sample checked as well.
Please take care,
