Pet's info: Dog | Miniature Schnauzer | Male | neutered | 6 years and 2 months old | 16 lbs
My mini schnauzer probably ingested some ibuprofen on Thursday night. He was checked out by a vet on Friday and his blood levels were fine. He hasn't eaten in the last few days and his last stool was black

Oh no, poor Ben! It sounds like he has blood in his stool from the upper intestinal tract. Ibuprofen can cause internal bleeding, bleeding disorders, and GI ulcers, and any of these could cause the blood to appear in his stool. It is concerning that he hasn't eating for the last few days, and this combined with his black stool, he needs to see a vet immediately. Too much ibuprofen can cause kidney and liver damage as well as other effects, and he need blood tests as well as treatment for his bloody stool. I see you live in San Mateo, CA. The North Peninsula Veterinary Emergency Clinic is open 24/7, and I would take Ben into them for treatment. Good luck, I hope he ends up ok!
