Putting a pacemaker in a dog may sound high-tech and far-fetched, but the practice is neither as uncommon nor as costly as you might think. As human pacemakers have become fairly routine, lower prices and increased availability have made them an option for dogs also.

Pacemakers are useful treatment of abnormal heart rate conditions that don't respond well to drug treatment, such as sinus node dysfunction (sick sinus syndrome) or heart block.

Pacemakers allow many dogs to return to their normal day to day activities, and most of them can enjoy a relatively normal life expectancy.
