Welcome to Justanswer! I am Dr. Altman and happy to assist you both today!Luckily 3 grapes in an adult Rottie will not cause any issues whatsoever, I wouldn't expect to even see gi upset in this scenario. At this time, the lowest documented toxic grape or raisin dose is 0.32 to 0.65 oz/kg. So if your Rottie is 40 kg this would mean 12 ounces would need to be ingested to be of concern and each grape is about 2 ounces so you can imagine the amount that would require this toxic change!So I wouldn't do anything at this point, your dog should be just fine, just no more grapes in the future :)Please let me know how else I can assist you both today!If you have more questions or if I can help in any other way, please do not hesitate to ask!
