I hope the north east of England is enjoying as beautiful a day as is the south of France! It finally feels like spring is coming.... ahhh!
I am not sure what that dewormer would be, as it may not be the same shape as what I am familiar with in Canada, even if it is the same medication.
I totally agree with your vet though. I recommend deworming my patients every 2 weeks up to 12 weeks and then every 6 months after that. This new deworming protocol is based on the most current research and your vet sounds very up to date.
What you are describing with Jessie sounds like a roundworm infection. These are really common in puppies and very easily picked up.
Many pups get roundworms from their mothers before they are even born, or while nursing, but many pups will pick them up from stepping in other dogs' feces and then licking their paws clean or from eating mice.
The good news is that they are easy to get rid of!
We usually treat for roundworms with a medication that contains Pyrantel Pamoate. This is safe and effective against roundworms.
Treatment should be given as per the label, and repeated every 14 days to kill off any worms that are hatching out of eggs still in the intestines.

Now, you asked if the worms are dead when they are passed... unfortunately, the answer is no. The dewormer stuns them and they "let go" of their grip on the intestines. As they are dying, they are passed. However, they can sometimes still be alive for a few minutes after they are passed.
