Demand for pet first aid and CPR classes has increased as animal lovers look for ways to be prepared in an emergency. Until recently there was no standard for the canine and feline version of the procedure, despite the fact that laboratory animals were instrumental in developing CPR guidelines for people.
Fortunately sudden cardiac arrest is not as common in dogs as it is in people. It's thought that the condition in pets is closer to what occurs in young athletes with structural abnormalities of the heart muscle or a defect in the electrical circuitry. Pets can also suffer cardiac arrest due to difficulty breathing or a severe illness that also affects the heart.
Now that there's a CPR standard in place, I hope that veterinarians will be more proactive about getting this information out to pet parents. I would also like to see pet first aid certification becoming a requirement for those who work in animal-related fields like pet stores or doggy daycares.
