Dog Vitamin D Deficiency Symptoms

Did you know that dogs can suffer from Vitamin D Deficiency just like humans? In fact, it’s quite common for dogs to develop this condition, especially if they spend most of their time indoors. Unfortunately, many dog owners are not aware of the symptoms of Vitamin D Deficiency in dogs, which can lead to serious health problems if left untreated.

So, what exactly is Vitamin D Deficiency?

Well, it occurs when there is a lack of vitamin D in the body. This can happen for a number of reasons, including not getting enough sunlight or not eating a balanced diet. Vitamin D is essential for the body to absorb calcium and phosphorus, which are necessary for strong bones and teeth. Without enough vitamin D, the bones can become weak and brittle.

Vitamin D3 levels in dogs are thought to be 100 to 120 ng/mL. Vitamin D deficiency is defined as less than 100 ng/mL.

Activation of Vitamin D:

Vitamin D3 is produced in the skin upon exposure to ultraviolet B (UVB) radiation from sunlight. It is then converted in the liver to 25-hydroxyvitamin D3 and then in the kidney to its active form, 1,25-dihydroxyvitamin D3.

The main function of vitamin D is to maintain serum calcium concentrations within a narrow range so that bone formation and mineralization can occur. Vitamin D achieves this by increasing the absorption of dietary calcium and phosphorus from the gastrointestinal tract and by stimulating osteoclasts, which resorb bone to release calcium into the blood.

7-DHC: 7-Dehydrocholesterol is a sterol found in the body that can be converted to vitamin D3 upon exposure to UVB radiation.

25(OH)D: 25-Hydroxyvitamin D, also known as calcidiol, is the major circulating form of vitamin D. It is produced in the liver from 7-dehydrocholesterol and then converted to its active form, 1,25-dihydroxyvitamin D3, in the kidney.

1,25(OH)2D: 1,25-Dihydroxyvitamin D3, also known as calcitriol, is the active form of vitamin D. It is produced in the kidney from 25-hydroxyvitamin D3.

Uses of Vitamin D:

  1. Vitamin D is essential for many different functions in the body, including:
  2. -Bone health: Vitamin D helps the body absorb calcium and phosphorus, which are necessary for strong bones and teeth. Without enough vitamin D, the bones can become weak and brittle.
  3. -Muscle function: Vitamin D is needed for muscle contraction and relaxation.
  4. -Immune function: Vitamin D helps the body fight off infections and diseases.
  5. -Nervous system function: Vitamin D is necessary for proper nerve function.

Sources of Vitamin D:

There are two main sources of vitamin D:

-Sunlight: The best source of vitamin D is sunlight. The body can produce vitamin D when the skin is exposed to the sun. However, this process is not always reliable, especially during the winter months or for people who live in northern climates.

-Diet: Liver, fish and egg yolks are some key sources of Vitamin D.

-Dietary supplements: Another source of vitamin D is dietary supplements. Supplements are available in a variety of forms, including capsules, tablets, and liquids.

What are the symptoms of Vitamin D Deficiency in dogs?

The most common symptom of vitamin D deficiency in dogs is bone abnormalities. This can include softening of the bones, joint pain, and deformities. dogs may also suffer from muscle weakness, seizures, and lethargy. If your dog is showing any of these symptoms, it’s important to take them to the vet for a check-up.

The symptoms of vitamin D deficiency can vary depending on the severity of the deficiency. In mild cases, the symptoms may be barely noticeable. However, in severe cases, the symptoms can be quite serious and even life-threatening.

Diagnosing Vitamin D Deficiency:

If you suspect that your dog has vitamin D deficiency, it is important to take them to the vet for a diagnosis. The vet will likely do a physical examination and order some blood tests. The blood tests will measure the level of vitamin D in the blood.

Treating Vitamin D Deficiency:

AAFCo Requirements for Vitamin D in Dog Food:

AAFCO requires dog food manufacturers to formulate kibble that meets specific minimum nutrients. Adult dog food should contain a minimum of 500 international units (IU) of vitamin D per kilogram of diet, and no more than 3,000 IU per kilogram.

Fat-soluble vitamin:

Vitamin D is a fat-soluble vitamin, which means it is stored in the body’s fatty tissue. The body can store vitamin D for months, and even years. However, when the stores of vitamin D are depleted, the body is at risk for deficiency.

Water-soluble vitamin:

Vitamin D is not a water-soluble vitamin, which means it is not easily lost from the body through urine. However, certain conditions, such as kidney disease, can cause vitamin D to be excreted in the urine and lead to deficiency.

Vitamin D toxicity:

Vitamin D is a fat-soluble vitamin, which means it can build up in the body and cause toxicity. Symptoms of vitamin D toxicity include:

-Excessive thirst

-Frequent urination

-Lethargy

-Loss of appetite

-Weight loss

-Muscle weakness

-Bone pain

Kidney failure

There are two main types of vitamin D:

-Vitamin D2 (ergocalciferol): This form of vitamin D is found in plants.

-Vitamin D3 (cholecalciferol): This form of vitamin D is found in animal products, such as eggs and fish.

Vitamin D2 is the form of vitamin D that is typically used in supplements. Vitamin D3 is the form of vitamin D that is typically found in food.
