It's not advised to give him deworming when he is vomiting, because it will likely just be vomited up. Worms can get in the stomach (not their usual place) and cause vomiting, but they don't tend to cause them to suddenly get weak. It's possible that some other infection (like parvo virus) is happening and the appearance of the worm was just a coincidence. Puppies that vomit a great deal can quickly become dehydrated, which will cause them to get weak. In order to keep Chopper from having life-threatening complications, it's best to take him to the vet for an evaluation and treatment as soon as possible. For now, only feed small amounts of bland food and make sure he has plenty of clean water. You can add rehydration salts to the water to help treat the dehydration. I hope that helps and Chopper gets better soon.
