Anemia is an indicator of compromised health in a dog. It has a variety of causes, from trauma-related blood loss to immune-mediated diseases like infection or cancer, and treatment is based on specific causes. Though severe anemia is life-threatening and requires immediate veterinary attention, mild cases can be easier to reverse or manage. Pale gums, lethargy, or weight loss may all indicate anemia and should be investigated by a veterinarian to determine the cause and course of treatment.
Anemia refers to a condition in which a dog's blood has low red cells and/or hemoglobin, a component of blood that delivers oxygen to the cells and tissues of the body. It is not a specific disease but the result of a disease process or blood loss.
A dog's symptoms of anemia may be subtle at first, mimicking fatigue from exercise or just having an "off" day, but they will get progressively worse over several weeks.
Anemia symptoms reflect a lack of oxygen in a dog's blood, indicating that the dog is not capable of performing normal daily activities due to tiredness. While appetite loss and sluggishness can accompany other problems, they are often indicative of anemia. Combined with the appearance of pale skin and gums, the more vague symptoms of anemia are important initial clues in the diagnostic process.
Red blood cells are produced by the bone marrow and then released into a dog's circulatory system. As the red blood cells age or become damaged, they are removed from the bloodstream and get recycled to form new red blood cells. The number of circulating red blood cells may drop for any of the following reasons:
Your vet will examine your dog and perform tests to form a diagnosis. These will most likely include a complete blood count (CBC), tests for parasites, evaluations of liver, kidney, and pancreatic functions, electrolyte tests to check for dehydration, a urinalysis to check for urinary tract infections, X-rays or ultrasound to look for internal bleeding, and other tests to rule out certain causes.
Once anemia is confirmed, then the process of finding the cause begins. This may involve X-rays, liver enzyme tests, endoscopy to evaluate the condition of the gastrointestinal tract, urinalysis, and fecal analysis to check for sources of bleeding.
Treatment for anemia in dogs depends on the cause of the condition. Many causes of anemia can be treated, managed, or cured with the help of your veterinarian.
Treatment goals for dogs with anemia are to control bleeding, restore blood volume, find and resolve underlying causes of chronic blood loss, and provide supportive care.
The prognosis for a dog with anemia depends on the cause of the condition, which may be minor and easily remedied, or serious and potentially life-threatening.
Certain causes of anemia can be prevented with measures such as flea and tick management, accident and trauma prevention, keeping toxins like rat poison and human medications (like ibuprofen and acetaminophen) away from your dog, and scheduling regular veterinary wellness checks.
Preventative care is just as important for pets as it is for their owners. Often, dogs will not show symptoms of a health issue, but a veterinarian can help detect and sometimes prevent disease and other life-threatening conditions during regular exams.
