Introduction: Understanding a Low Heart Rate in Dogs
A low heart rate in dogs, also known as bradycardia, refers to a heart rate that is slower than the normal range for a dog’s breed, age, and size. A dog’s heart rate is an essential indicator of its health, as it pumps blood throughout the body and supplies oxygen to vital organs. A low heart rate in dogs may indicate an underlying health problem, and it is essential to identify and treat the cause to prevent complications.
Normal Heart Rate for Dogs: What to Expect
A dog’s heart rate varies according to its breed, age, size, and activity level. On average, a dog’s heart rate ranges between 60 to 140 beats per minute (bpm). Smaller breeds tend to have a faster heart rate than larger breeds. Puppies and younger dogs usually have a higher heart rate than adult dogs. During exercise or excitement, a dog’s heart rate may increase significantly, but it should return to a resting rate within a few minutes.
Causes of a Low Heart Rate in Dogs: Overview
A low heart rate in dogs can result from a variety of factors, including health conditions, medications, supplements, environmental factors, breed predisposition, age, and physical condition. Some common causes of a low heart rate in dogs include heart disease, hypothyroidism, electrolyte imbalances, certain medications (such as beta-blockers and calcium channel blockers), exposure to toxins, and extreme temperatures. It is crucial to identify the underlying cause to determine the appropriate treatment for a low heart rate in dogs.
