Oscar vomits one time in a day and has black poop. What it means. Is this can be dangerous to his life because my previous puppy died like this.

I am sorry to hear that Oscar is so ill. His symptoms are very suspicious of parvovirus, which can be lethal to pets. He could also have intestinal parasites. The black stool indicates that he may have some blood in his poop. You should take him to your local vet to get tested. If he does have parvovirus then he needs treatment (i.e. antibiotics, fluids, pain medication) through your vet for any chance of survival. If he only has intestinal parasites, then the vet can prescribe the appropriate dewormer based on which parasites are present on his fecal exam. I hope your puppy gets well soon and does not meet the same fate as your other poop puppy. If your pup does well, then make it a point to get Oscar vaccinated soon to protect him from deadly viruses like parvovirus and others, which are totally preventable through regular immunizations. Best wishes!
