What is Iron Deficiency Anemia in Dogs?

There are different types of anemia that can affect your pet’s quality of life, but one of the most common is iron deficiency anemia.

It is a type of anemia that decreases the amount of red blood cells needed for your pet’s body to function properly.

Red blood cells are responsible for transporting oxygen to all the tissues in the body, which is why they play such an important role.

Iron is vital for hemoglobin to exist.

Without this essential resource that your pet needs, his body will be exposed to this type of disease.

In short, it is a considerable deficiency of iron in your dog’s body that does not allow him to have a good quality of life.

Iron Deficiency in Dog Causes

There are several causes that can trigger iron deficiency anemia in your pet.

Such as severe and exaggerated blood loss caused by injury, internal or external bleeding, ulcers, tumors, trauma or even a parasite that completely affects the digestive tract.

However, there are also some other possible causes that contribute to the severity of anemia.

If your dog has had a deficiency of vitamins, minerals, proteins, that is, an unhealthy and unbalanced diet can lead to this type of anemia.

That is why it is so important to feed our furry friends with a healthy diet rich in all the nutrients their body needs.

Although you do not feel guilty, since not everything is the fault of a poor or unhealthy diet.

There are people who feed their pets with the best nutritional supplements that their body requires.

But your pet may suffer from inflammatory bowel disease, which does not allow proper absorption of iron in the blood.

There may also be the possibility that your pet’s body is demanding much more iron than it is already being fed, this happens when there is a growth spurt.

Or when a bitch is in her gestation period. Since those are the most vulnerable moments where the organism will need much more iron.

And last but not least, it can also be caused by the destruction of red blood cells by the same immune system as your dog.

Symptoms of Iron Deficiency in Dogs

In general, the symptoms of this disease can be quite varied.

As it depends specifically on the severity and cause that has led to your pet having a noticeable iron deficiency.

When iron deficiency begins to take its toll on your furry friend’s body, you will quickly notice strange behavior and a radical change.

So if you notice the following symptoms in your pet, it is best to take him to a veterinarian as soon as possible.

1. If your pet is very active and playful, you will notice that he is weak, overtired all the time, without energy and somewhat apathetic towards everything, even games.

2. You may notice that his mucous membranes show a pale color that he did not have before.

The mucous membranes are the gums, ears or eyelids.

3. Although it is a symptom that we cannot easily detect ourselves, he may also present an accelerated heart rate for no apparent reason.

4. Shortness of breath, in other words, will show dyspnea.

5. Loss of weight and appetite. This is a very common symptom and may help you suspect that something is wrong.

Iron Deficiency in Dog Diagnosis

In order to have a more accurate diagnosis and thus know if our pet has iron deficiency.

It is required to have its clinical history, a physical examination.

And also blood tests in the laboratory in order to carry out the following procedures.

Blood analysis

It measures the amount of red blood cells in the blood, their different sizes and the level of hemoglobin and hematocrit.

If your pet has hematocrit values that vary between 39% and 60%, and for hemoglobin 12 or 18g/dL, then it is within the normal range.

On the other hand, if hematocrit values are below 39% and hemoglobin below 12g/dL then it is indicative of iron deficiency anemia.

Biochemical profile

This test measures the level of iron and ferritin in the serum.

Ferritin is the protein that stores iron in your pet’s body.

If low levels of both are found, then ferritin deficiency is present.

Blood Smear

It is the procedure in which the red blood cells are observed from the microscope to analyze their shape and color.

When there is the presence of iron deficiency anemia.

Then microcytic and hypochromic red blood cells with a light colored center can be observed.

Biopsy

To perform a biopsy it is important to extract a small sample of the tissue.

Where the red blood cells are found to be observed under the microscope.

This test is one of the most accurate, as it can easily detect iron deficiency in bone marrow.

How much iron does a Dog Need Daily?

To treat iron deficiency anemia in your pet more effectively, it is necessary that iron-rich foods.

Such as red meats, eggs, whole grains, organ meats, among others, are included in his diet on a daily basis.

Veterinarians recommend an intake of 35mg of iron per pound of dog food.

But for dogs with iron deficiency anemia, a daily intake of 80mg/kg of body weight is necessary to counteract the negative effects of this disease.
