Think my dog has roundworms. Will treatment at her age make her sick or worse?

Treatment should not harm her as long as she is otherwise healthy. The most common side effect of a deworming is some minor stomach upset (vomiting or diarrhea). Not treating her is far riskier to her overall health. Consider a monthly preventative that will protect against heartworm as well as the 3 most common intestinal parasites: hookworm, whipworm and roundworm. Discuss options/products with your veterinarian.
