Yesterday, I buried one of Fifi's puppy. As I observed him, he was crying in pain. I think he is running out of oxygen. I pity him watching fighting to survive. He vomited and poo worms. I couldn't do anything to help him only to watched him. It will be avoided if I send him to the nearest veterinary office. His siblings experienced that same thing but they survive. I told them this is the survival of the fittest. I don't know if I can sell them. From seven puppies down to six. I don't know when will I keep them.
