[MENTION=1652]Angelgirl[/MENTION] if you are going to spend that amount on dog food, you really should try Fromm. It is way better than RC, and I think you would be really happy with it. RC spends a heafty amount on advertising- which gets taken out of the quality of the food. Pretty much anything you can get at a pet retailer is always going to be a second or back up choice if possible, the reason you do not find many of the best brands at pet retailers is because they wont make enough $$$ selling it.

They should be able to see eggs. Fully developed parasites lay eggs. You treat them with de-wormer, and kill all the adult and young worms. But the eggs still hatch. So in 10 days you need to retreat, before the worms become egg layers, and after all eggs have hatched. Doing it a 3rd time is not a bad idea too.
Here is the thing, I have had several bully puppies and about 4 of them had worms. So I kept 'going back to the vet'..... 'come back in a month'.... 'oh dear the worms are not gone'..... 'lets do a recheck'..... I remember on Molly alone I spent over $1000 the first 3 months. So I went online to learn about these worms and that is what I found out!!! The vet was not scheduling me back at the right day, and I think it was on purpose!
If you really want to deworm on your own, you can. You can order dewormer online, it is not expensive, and you can treat yourself and save a fortune.
BUT, with that being said, you should also make sure it is not coccidia or giardia, which does require a different medication. But I anticipate that if you bring up the life cycle of the worm and the egg hatching cycle your vet will be pretty inclined to have you back in their office on the EXACT day the medication requires.
For regular worms the medicine goes every 10 days, but I have used a more expensive product called Safeguard which also clears giardia, and that was given every two weeks.
