call the spca you can be legaly responsible for not getting this puppy help when you knew it was sick it is a crime if you can not afford to help the dog take it to the local shelter and they will determin if they can save the puppie or not why do people think the only cost of a dog is the money it cost to buy one !! it makes me so mad !!!!
btw kennel sol or good old bleach every surface you can that puppie touched your shoes everyone who walks on parvo can carry out your door and into my home vets office ect tell the local shelter what you the dog has so they can take it in the back so as to not infect any small puppies there for first shots !
