My spayed dog got an extra Rimadyl dose for pain. Is she okay?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female | spayed | 7 months and 1 day old | 15 lbs

My dog is 15lbs. She was just spayed. She is prescribed 75mg Rimadyl, 1/2 pill a day. She woke up in pain and was crying/whimpering 2:30am so I gave it to her. She has had the following doses: Wed 9am (guessing) 37.5mg, Thurs 2:30am 37.5mg, Thurs 9am 37.5mg. She won't get any more until tomorrow morn at 9am. She ate her breakfast and did not get sick and is her playful self right now. Are we ok? Or should I be concerned? I would think if life-threatening would be on the LABEL.

Hi there. So if I'm understanding correctly, it sounds like she just had one extra dose of Rimadyl at 2:30 am Thursday morning - is that right? While it's true that we always want to stick to the label dosage with this medication, as there is a risk of causing serious side effect issues with higher doses and/or giving it more frequently than prescribed, I would generally not expect to see any major issues with just one accidental "extra" dose. Most of the toxicity issues we see with this medication are related to dogs getting into the bottle and eating a large number of pills at once, or with chronic overdosing over a longer period of time. If your girl is acting normal, eating and drinking fine, and not vomiting, then I don't see any major cause for concern right now. I would definitely recommend calling your regular vet to let them know about the extra dose and make sure they don't recommend doing anything different - but otherwise, I would just monitor her for any problems, and stick to the prescribed dosing schedule from here on out. The main things to watch for would be vomiting, or not eating - if you see either of those symptoms, I would let your vet know right away. If you feel like she's still somewhat painful in between Rimadyl doses, you could also ask your vet about getting her a different pain medication that would be safe to give along with the Rimadyl if she seems painful at night before her next scheduled dose, such as tramadol or gabapentin.
