We often treat a pet symptomatically before test results are available to us. I can only assume that your vet had enough evidence to suggest that Dee was hypertensive, warranting the use of Sildanefil, and also had signs of bronchospasms or breathing difficulty, warranting the use of Theophylline. I am unsure of your pets clinical signs to confirm this, but this would be a logical explanation. But ultimately if you want to 100% know why these medications were prescribed then it would not be considered rude or unheard of to ask your vet their logic behind this decision. It is always best to hear the information from the source rather than speculation from an outside source.
