I get concerned with things a lot sooner with such a young puppy. The watery blood would make me recommend an exam by itself. I would want a urine sample to see if there is blood in the urine. The pustules have me concerned about a bacterial infection. I would recommend taking him in for an evaluation by a veterinarian. He might need to be on antibiotics or at least a topical medication.

    Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor baby! Be gentle when stimulating him to urinate. Use a soft towel and warm water. The blood could be from trauma or a urinary tract infection. The pustule could be from a skin infection or urine scalding. Make sure he isn’t laying in urine. If you find him wet bathe him and dry him well. I would have him seen by a Vet sooner than later because newborns are very fragile. He may need antibiotics. I hope this helps and I wish Puppy the best!
