Common Nutritional Deficiencies in Dogs that You Need to Supplement

One of the fundamentals to ensuring your dog lives a long, healthy life is to provide him a nutritional, well-balanced diet. A lot of owners trust pet food companies when they claim that their formulas are either recommended or designed by vets and that they have animal nutritionists on their teams. If you feed your dog a nutritionally complete diet that does not mean that he is getting everything he needs.

Although rare, dogs too can become prone to nutrient deficiencies. Here are some of the reasons why this might happen:

    1. Your dog does not get enough nutrients to maintain his health
    2. Your dog has parasites that feed off his nutrients
    3. Your dog has a health problem that prevents him from assimilating food into the proper nutrient components to retain health.
    4. Your dog eats homemade food. Heat from cooking destroys nutrients, and can easily result in a vitamin deficiency
    5. Your dog eats too much. Obese dogs can become nutrient deficient as well.

When your dog becomes deficient in a certain vitamin or mineral, a good way around that problem is through giving him supplements. Listed below are 3 nutritional deficiencies in dogs that you need to supplement.

1. Reduced Levels of Vitamin D

Being deficient in vitamin D can lead to a plethora of problems related to his bone health. They can also develop bowed legs swollen joints, and other symptoms associated bone diseases such as rickets. Too much of the vitamin can significantly increase the amount of calcium stored in the canine’s muscles and heart, along with diarrhea, vomiting, excessive urination and thirst, bone pain, lethargy and hemorrhaging. And because vitamin D is very difficult to obtain from the diet, you will want to go for a multivitamin that contains plant-based nutrients and minerals that offers a good supply of vitamin D for your dog.

2. Omega 3 and Omega 6 fats

Omega 3 and omega 6 are essential fatty acids for dogs that help with proper development and growth of organs, joints, tissue, and intestines, and also act as lubrication for the digestive tract, joints, and improve heart health.  Symptoms that your dog might be deficient in omegas include yeast infections, eye and skin issues, allergies, cancer, organ problems, and even behavioral issues. A good way to make for the lack of omega fatty acids is through purchasing good quality supplements from your vet.

3. Vitamin A (Beta Carotene) Deficiency

Common Nutritional Deficiencies in Dogs that You Need to SupplementDogs that are deficient in vitamin A tend to have a weaker immune system, which means they are more prone to sickness, poor skin quality, and nighttime blindness. If you see that your dog is starting to have drier skin, chances are that he might be deficient in vitamin A. you can easily fix this problem by feeding your pooch vitamin A supplements or even multivitamins.

Before you choose any form of supplements for your dog, make sure to consult with your vet and ask for recommendations and directions about where to buy them.

The Top Vitamins Your Pet Needs Supplements For

Animals require essential vitamins to stabilize their bodily functions. Luckily, more and more pet owners are realizing this. This is proved by a 2006 study published in the Journal of the American Veterinary Medical Association. It stated that almost a third of cats and dogs in the US receive supplements of some sort. Over a decade later, this fraction has gradually increased.

The cases in which your pets should be given supplements are if they suffer from a vitamin deficiency or some disease in which they can respond to supplements. Other cases can be if your pets are picky about the food you give them or eat meals that are prepared at home, both lead to a nutritionally imbalanced diet.

The Importance of Vitamins

Vitamin A serves as an important factor in the growth and fetal development in animals. It synthesizes proteins for the metabolic process as well as hormones for reproduction. It ensures stable growth in epidermis cells, which make up the skin. It helps in maintaining a healthy immune system. Like humans, vitamin A is important for animals to have good eyesight. However, cats face a higher risk of deficiency since they require a form of vitamin A as already present in the liver. Therefore, they have a higher need for supplementation. Deficiency in animals can lead to issues such as reduced vision in the dark, skin problems and complications in reproducing. It can also lead pets being easily prone infections.

B vitamins make a significant contribution to many processes and functions within the body. Vitamin B1, also known as thiamine, is essential for the functioning of the nervous system as well as energy production in their cells. This is done by metabolizing carbohydrates that are the main source of energy for all other body functions. Reasons for deficiency can vary from an imbalanced diet to a disease that prevents the small intestine from absorbing thiamine.

Supplementation becomes crucial in these situations, otherwise symptoms like poor muscle growth and weakness may occur. Vitamin B3, which also referred to as niacin, is important for protein synthesis and other chemical reactions in the body. Cats are generally at higher risk of developing a deficiency if they do not intake adequate sources of B3 in their diet.

This is because their bodies are unable to produce sufficient B3 for proper functioning. Supplements become necessary to avoid symptoms such as dermatitis or diarrhea. B9 is commonly known as folate and is crucial for rapid cell division as in the process of fetal development. Supplementation for female animals has a beneficial effect on fetal growth whereas a deficiency can lead to the fetus having malformed features.

Vitamin D is important in balancing the level of calcium and phosphorus minerals in the blood. It allows the conservation of calcium in the kidneys and is important for bone formation and muscle control. Mammals are able to synthesize it within their skin cells, but cats and dogs cannot, which is why you have to provide them with necessary supplementation.

Vitamin E helps in the production of the cell membrane, and since the main source of this vitamins are plant oils, carnivorous pets are likely to develop deficiencies. Therefore, supplements can become important to ensure a healthy functioning of the body.
