A dog needs holistic nutrition from their food with ample carbohydrates, fats, proteins, vitamins, and minerals to live a happy and healthy life.

However, it can be tricky to figure out if they’re getting everything they need from their meals. Knowing the signs and symptoms of vitamin deficiencies in dogs and investing in the right supplements can ensure your dog is receiving everything they need to thrive.

The role of vitamins in a balanced diet

The eating habits we set our dogs up for can mean the difference between a long and healthy life and a poor quality of life with frequent rounds to the vet. Vitamins that are tailored to a dog’s individual needs are considered to be a significant aspect of canine nutritional needs at every stage of their life. Vitamins ease the transition from puppyhood to an adult canine companion, all the way to seniority.

They have a plethora of benefits, including but not limited to –

  • Fighting diseases
  • Increasing energy levels
  • Promoting healthy skin and coat
  • Strengthening bones and joints
  • Boosting immune system
  • Increase absorption rate of nutrients from food
  • Increasing metabolism
  • Improving cognitive functioning and development

Signs of vitamin deficiency in dogs

The three main causes of vitamin deficiency could include lack of food, lack of nutritional ingredients in food and digestive diseases that may prevent the absorption of these nutrients.

The most obvious signs of vitamin deficiency include –

  • Changes in bowel movement: color, consistency, content, and coating
  • Skin and coat changes, including but not limited to hair loss, skin disease, and infection
  • Behavioral changes like lethargy, depression, etc
  • Lack of energy

Some other signs could include –

  • Loss of appetite
  • Discoloration of tongue
  • Blood clotting problems
  • Changes in body temperature
  • Neurological problems
  • Difficulty in reproduction

Diagnostics for a dog that is experiencing the symptoms of poor nutrition and deficiencies start with a physical examination including standard tests such as a urinalysis, a biochemical profile, and a complete blood count. A fecal float can help uncover the presence of any parasites residing in the dog’s body. Skin samples may be examined microscopically if the skin has been affected by malnutrition and deficiency.

How to choose the best vitamin for your dog

Once you have figured out your dog’s nutritional and supplemental needs in terms of vitamins, the last and most important thing to do is pick out a vitamin that suits your dog’s needs. Remember the following pointers while purchasing your dog’s vitamins and supplements-

  • Keep it simple. Avoid getting too many vitamins and supplements that may disrupt and confuse your dog’s system
  • A stamp of approval from NASC (National Animal Supplement Council)
  • Consult your vet to ensure that your dog is getting the appropriate vitamins and minerals as per their nutritional needs
  • Check for brand, history, recalls, and controversies
  • Read and understand the ingredients of the product and make sure your dog is not allergic to any of them

What essential vitamins do dogs need?

There are essentially 2 types of vitamins every dog needs: Water soluble vitamins and fat-soluble vitamins

Water-soluble vitamins, as the name suggests, dissolve in water. They’re constantly being flushed out of the body, hence, regular top-ups are needed.

Fat-soluble vitamins are vitamins that are found in animal fat. A dog’s body absorbs them through their intestine and stores them for later use.

Vitamin B1: ThiamineStrengthens immune response Important to break down carbohydrates
Vitamin B2: RiboflavinPromotes eye health Important for blood cell production
Vitamin B3: NiacinImproves metabolism Catalyst for hormone productions
Vitamin B5: Pantothenic acidNecessary for protein absorption and fatty acids
Vitamin B6: PyridoxineRegulates sodium and potassium levels in the body Improves cognitive function
Vitamin B7: BiotinImportant for healthy skin
Vitamin B9: Folic acidEssential for DNA synthesis
Vitamin B12: CobalaminBetter nerve function
Vitamin CImportant antioxidant Reduces inflammation
Vitamin AHealthy eyes Important for the healthy functioning of organs and the immune system
Vitamin DBalances minerals and phosphorus
Vitamin Edefenses against oxidative damage
Vitamin KActivates blood’s ability to clot

How much vitamins do dogs need?

The nutritional and supplemental needs of a dog vary depending on the stage of life they are in and deficiencies if any.

If your dog is consuming well-balanced and nutritious dog food that is sourced from high-quality, organic ingredients, vitamin supplements may not be necessary as their meals contain the right proportion of vitamins and minerals. In such cases, supplements could do more harm than good.

A quick blood test would help you find out if there are any deficiencies in your dog and if they need additional vitamins and supplements. Your vet and/ or dog nutritionist will be able to give you accurate information.

Bottom Line

With just one single tab, your pooch will be able to get their daily dose of vitamins, minerals, fatty acids, and powerful antioxidants.
