Black stool is indeed concerning, and if Achilles did in fact eat Aleve this would indicate bleeding inside the GI tract. I'm sure your vet advised you to be alert to this complication. Sucralfate can help when there are GI ulcers (this is one of the complications caused by an overdose of NSAIDs) but it may not be all he needs to recover successfully. Often these dogs sustain liver and kidney damage, and need to recover in a hospital with IV fluid therapy. Finally, depending on how much he ingested, he may be at risk for perforation of the stomach, and this is an extremely serious complication that requires surgery. If he is not doing well at this point I would urge you to seek immediate follow-up care.
