Can you recommend a good all purpose worm medicine for a miniature long-haired daschund? They range from 8 -20 pounds.

I keep my dogs on Revolution in the flea season and Heartgard+ the rest of the year. Both kill many other worms besides heartworms. Both must come from the vet, so take a stool sample and see what your vet says.

There over the counter medicines, but you still need heartworm medicine.
