I would definitely puppy proof the house, so that he/they are in a safe environment. If that is not possible, how about an x-pen to keep them confined? I would also ask the vets for copies of all the test results...post those results here. Also, I think the aspirin may very well have caused the bleeding...even though it was a small amount. I'd want to be sure whether the abnormal test results are liver, kidney or pancreas related. Hope and pray the next test results come back much better. Too much protein, too much fat...too much indigestible objects...hard to say. Hope there is no permanent damage and he keeps getting better each and every day.
