My puppy has had diarrhea since last night and it got better earlier (more solid) but then got much worse. She threw up the dewormer meds the vet gave her and now has bloody diarrhea.

Oh goodness. I am so sorry to hear that Bambi is so sick. I am very concerned about parvovirus with the symptoms that you describe. I would highly encourage you to have her evaluated by a veterinarian immediately. At 1.4 pounds she can become severely dehydrated very quickly. Best of luck and I hope she improves soon. Thank you for using Pet Coach.
