severe case of worms

Question
I have a collie i had him sence i was 4 im 20 now hes male
he has a severe case of worms. hes been vomiting and not eating im wondering if there is a cure

Answer
It depends on what kind of worms he has.  If its roundworms (they can sometimes vomit these up) then there are treatments you can buy over the counter.  If he has roundworms, though, there's a good possibility that he has other intestinal parasites, so I would recommend taking a fecal sample in to your vet so they can check.  It's much cheaper in the long run because they have dewormers that can kill many different parasites, and you can't buy them over the counter.  Since he's an older dog and he is vomiting and not eating, I would suggest taking him in for a physical any way.  The worms could just be a coincidence and he could have other problems as well.
