Thanks for using Petco Pet Education Center, formerly Petcoach. Nine days is a bit long to be related to the vaccines. The stool in the picture looks normal to me. I’m not sure what HB is -perhaps posting a picture of the bloodwork could help us. The platelets are a little low. Drinking and urinating a lot could be a sign of infection but is often completely normal for puppies. Long story short, if the fever is persisting this long, something else may be going on. Perhaps there is a tick borne- or other disease which can cause fever and also low platelet count. I recommend seeing your vet for re-evaluation to help see what is going on. Best wishes to you and Billu!
