Blood in the vomit is definitely cause for concern, as it can indicate stomach ulcers, stomach parasites, or even a foreign body. As puppies are prone to getting into things they shouldn't, Simba may have ingested a toxin such as human pain medication or a piece of a toy. It is concerning that Simba did not feel well after vomiting. I recommend having him seen by a vet as vomiting blood can be a sign of a serious underlying condition. Your vet can perform bloodwork and x-rays to rule out the conditions above.
