The old saying, "an ounce of prevention is worth a pound of cure" definitely holds true when it comes to pet health. Vaccinations, heartworm prevention and routine deworming are important components of wellness care and can prevent diseases that are not only life-threatening, but very expensive to treat. The cost of prevention is often a fraction of the cost of treating a disease or problem once it has become more advanced, and early diagnosis and treatment of developing problems or diseases can increase the likelihood of successful outcomes.
