So i wouldn't have to give my pup another deworming medicine after she had her first one but played with a dog that didn't have the medicine yet?

She will have to have another deworming treatment two weeks after the first. It takes at least two deworming treatments to kill all the worms. The first kills the adults present at the time of the first treatment, and the second kills the ones who had not yet hatched at the time of the first treatment. Depending on her age, she will need one every two weeks until she is 12 weeks old. Then one every month until she is six months of age, and after that she should be dewormed once every three months. Same for your other dog. This is to prevent them for getting reinfected with worms.
