The Fourth of July is our country's birthday. When grandchildren ask why, tell them what happened on July 4, 1776. That was the day our country's founders declared independence from Great Britain. This meant they would no longer follow the orders of Britain's king.
Normal Puppy Heart Rate. Though the heart rate will vary depending on your dog's breed, the normal heart rate for puppies is around 220 beats per minute. As your dog matures, his normal heart rate will slow down to between 60 to 160 beats per minute depending on his size. Larger breeds have a slower heart rate than toy breeds.
All puppies should have their initial veterinary exam by twelve weeks of age so the heart functions can be monitored. Most congenital heart defects can be detected at this early age with the aid of a stethoscope. Many heart defects cause abnormal heart sounds called murmurs. Murmurs are the result of turbulent or abnormal blood flow created by narrowed vessels, valves, or abnormal openings between heart chambers.
