I'm sorry he's not feeling well
When Jackson was a pup they gave him the DHLPP shot and he had a bad reaction to the 'L' part (Lepto). A lot of small dogs do. I would never get it again~ Jackson just gets DPP (I think?) now, along with Rabies (but at different times). A lot of us Yorkie owners will only get the totally necessary vaccines and I would never get Rabies on the same day!
