Anemia in dogs is a serious condition that can be seen in a few different forms. Here, our Leighton vets discuss everything you should know about anemia in dogs.
Anemia in Dogs
In dogs, anemia is a condition that indicates that your pet is suffering from an underlying disease or illness. Anemia occurs when your pet's body isn't producing enough red blood cells, or hemoglobin. Anemia can also occur when your dog suffers severe blood loss due to conditions such as cancer, stomach ulcers, or serious injury.
Types of Anemia Seen in Dogs
Aplastic or Non-Regenerative Anemia
Aplastic or non-regenerative anemia develops in dogs due to insufficient production of red blood cells. This form of anemia can occur due to toxin exposure, bone marrow disease, kidney disease, certain medications, chemotherapy drugs, or parvovirus.
Blood Loss Anemia
Blood loss anemia occurs when your dog has experienced severe loss of blood due to an injury, surgery, or a bleeding disorder. This form of anemia could also be caused by internal bleeding due to cancer, ulcers, parasites, or other health conditions. Anemia caused by blood loss is a form of regenerative anemia. This is because although the bone marrow responds appropriately to the decreased number of red blood cells by increasing production it is unable to meet the demand.
Hemolytic anemia is caused by the destruction or breakdown of red blood cells in your dog's body. This form of anemia is often the result of immune-mediated hemolytic anemia (IMHA) or autoimmune hemolytic anemia (AIHA), or non-immune mediated caused by a hereditary disease, parasites, toxins, or low phosphorous levels.
Methemoglobinemia in dogs is caused by too much methemoglobin in the blood due to certain genetic disorders, or exposure to toxins including several different medications meant for human use only such as ibuprofen, acetaminophen, or benzocaine.
Signs of Anemia in Dogs
If your pooch is suffering from anemia you may notice one or more of the following symptoms. Your dog's anemia symptoms will vary based on the underlying cause of your pup's condition.
- Weight loss
- Fast pulse or rapid breathing
- Pale gums, ears, or eyes
- Lethargy or weakness
- Loss of appetite
- Swelling of the face or jaw
- Black stools
Causes of Anemia in Dogs
Several conditions can result in your pup developing anemia. Some of the most common causes of anemia in dogs include:
- Medications impacting red blood cell production
- Blood loss caused by parasites
- Kidney disease
- Cushing’s disease
- Infectious diseases
- Severe blood loss
- Toxins or poisons
- Tick-borne diseases
- Poor nutrition
- Bone marrow disease
- Intestinal bleeding
- Chronic diseases that suppress red blood cell production
Treating Anemia in Dogs
If your pup is diagnosed with anemia, the treatment that your vet recommends will be based on the underlying cause of the condition. Some of the treatments that your vet may recommend include:
- Blood transfusion
- Bone marrow transfusion
- Intravenous fluids
- Change of existing medications
- Antibiotics or immunosuppressive drugs
- Potassium phosphate supplements
- Gastrointestinal medication
- Parasite or de-worming medications
The prognosis for dogs with anemia depends upon the availability of effective treatment for the underlying illness. Severe anemia in dogs can indicate a very serious or possibly fatal condition such as poisoning, cancer, or an autoimmune condition. If your pooch is showing any signs of anemia contact your veterinarian as soon as possible.
Preventing Anemia in Dogs
Preventing anemia in your dog comes down to preventing the conditions that cause anemia (whenever possible). Year-round parasite prevention medications to protect your dog against ticks, fleas, and worms are one way to help your dog avoid developing anemia.
Keeping toxic substances such as human medications and foods far out of your dog's reach as well as providing your dog with a healthy diet, may also help to prevent your dog from developing anemia.
If your canine companion is a breed that is susceptible to developing anemia (Shih Tzus, Labrador Retrievers, Miniature Schnauzers, and American Cocker Spaniels) regular wellness examinations twice yearly at your primary care veterinarian may help to detect the signs of anemia early, and provide treatment before the condition becomes more severe.
