Vitamin A is essential for providing a range of critical benefits to your dog: from boosting immunity and improving vision, to helping with growth and tissue maintenance.
But just how much vitamin A does your dog need? And what are the best sources of this essential nutrient?
In this article, we'll dive into the details surrounding Vitamin A for dogs—offering expert advice on ways to ensure your dog receives the required amounts.
What is Vitamin A?
Vitamin A, an essential vitamin also known as retinol or retinoic acid, is a vital fat soluble vitamin that is used for a host of vital functions.
Perhaps most famously, Vitamin A is essential to vision – it plays a critical role in converting light into electrical signals in the retina.
However, that is just the beginning of what Vitamin A does. The nutrient is also crucial for proper growth and development, cell division, reproduction, and immunity.
And, on top of all that, Vitamin A has antioxidant properties that can help protect our cells from damage.
These antioxidants are particularly valuable because they might shield your dog's body from free radicals – molecules that can cause harm when produced in excess by our bodies' metabolic processes or exposure to environmental toxins.

Vitamin A and your dog's skin
A lack of vitamin A in dogs can lead to a variety of skin and coat problems.
In particular, adult dogs with a vitamin A deficiency often have patchy fur or bald spots, as well as dry and flaky skin. These skin issues can be accompanied by bumpy or lesion-like textures, which can be uncomfortable for dogs and lead to skin infections.
While there are other causes of skin problems in dogs, it's important to consider vitamin A deficiencies as a potential cause, as treating the deficiency can help improve overall skin and coat health.
If you suspect that your dog may have a vitamin A deficiency, it's best to consult with a veterinarian to determine the best course of treatment.
Sources of Vitamin A
Did you know that animals can get their daily dose of vitamin A by consuming foods that contain beta-carotene? Beta-carotene is an orange pigment found in many fruits and vegetables, such as carrots, sweet potatoes, and cod liver oil.
When consumed, beta-carotene is converted into vitamin A by the body, which is essential for healthy vision, immune function, and skin health in animals and humans alike.
Here are 8 food sources of Vitamin A rich foods for your dog.

While some dogs show rapid signs of vomiting, drowsiness, irritability, and peeling of the skin, others may present delayed effects.
These may include dehydration, joint pain, and even bone fractures in severe cases.
It's crucial for dog owners to monitor how much vitamin A their pets consume and know how to recognize the signs of toxicity to prevent any harm from happening.
