Ask a Dog Vet and Get Answers to Your Dog Veterinary Questions
Hello. Thanks for the question.
The crayons and tums don't worry me. Those are safe. If there was Advil, that is the part that would worry me. Any more than 7 tablets (1400 mg) can potentially cause kidney failure. Any more than 2 tablets can cause GI upset and ulcers.
If there was any Advil, then I would go to a vet and get bloodwork checked to make sure the liver and kidney function is ok. If it is, then some GI ulcer meds could be started. If there is kidney damage, then IV fluids to try to get the kidneys to regenerate would be needed.
I hope this helps, let me know if you have any other questions.
