Signs of Vitamin B7 Deficiency in Dogs

Dull and Dry Coat

One of the most noticeable signs of vitamin B7 deficiency in dogs is a dull and dry coat. If your dog’s fur lacks its natural shine and feels dry to the touch, it could be a sign that they are not getting enough vitamin B7. Biotin, also known as vitamin B7, plays a crucial role in maintaining healthy skin and coat. It promotes the production of fatty acids that keep the skin moisturized and the coat lustrous.

Hair Loss and Alopecia

Hair loss and alopecia are other common indicators of vitamin B7 deficiency in dogs. If you notice patches of fur missing or your dog is experiencing excessive shedding, it could be due to a lack of biotin. Biotin is essential for the production of keratin, the protein that makes up hair and nails. When there is a deficiency, the hair follicles become weak, leading to hair loss and thinning.

Skin Problems

Vitamin B7 deficiency can also manifest in various skin problems for dogs. It can cause dry, flaky skin, itchiness, and rashes. Additionally, your dog may develop skin infections more easily due to the weakened skin barrier. Biotin helps in maintaining proper skin health by supporting cell growth and repair. Without enough biotin, the skin’s integrity can be compromised, resulting in these skin issues.

Gastrointestinal Issues

Digestive problems can be another sign that your dog lacks vitamin B7. Biotin is involved in the metabolism of carbohydrates, proteins, and fats. It aids in breaking down food and converting it into energy. When there is a deficiency, your dog may experience symptoms such as diarrhea, vomiting, or a decreased appetite. These gastrointestinal issues can be a result of the body’s inability to properly digest and absorb nutrients.

Poor Growth and Muscle Weakness

In young dogs, vitamin B7 deficiency can hinder proper growth and development. Puppies may exhibit delayed growth or fail to gain weight at a healthy rate. In addition to poor growth, muscle weakness can also be a symptom of biotin deficiency. Biotin is necessary for muscle function and strength. Without enough of it, dogs may struggle with mobility and appear lethargic.

Causes of Vitamin B7 Deficiency in Dogs

Inadequate Diet

One of the primary causes of vitamin B7 deficiency in dogs is an inadequate diet. If your dog’s food lacks biotin-rich ingredients, they may not be getting enough of this essential vitamin. Commercial dog foods often contain synthetic sources of biotin, but these may not be as readily absorbed by your dog’s body as natural sources. It is important to ensure that your dog’s diet includes biotin-rich foods or consider supplementation if necessary.

Parasite Infections

Parasite infections, such as fleas or ticks, can contribute to vitamin B7 deficiency in dogs. These parasites feed on your dog’s blood, depleting their nutrient reserves. Biotin is one of the nutrients that can be affected by these blood-sucking parasites. Regularly checking your dog for parasites and promptly treating any infestations can help prevent vitamin B7 deficiency.

Malabsorption Disorders

Certain malabsorption disorders can interfere with your dog’s ability to absorb and utilize vitamin B7 efficiently. These conditions affect the gastrointestinal tract and can inhibit the absorption of nutrients, including biotin. If your dog has a malabsorption disorder, it is crucial to work closely with your veterinarian to manage the condition and ensure adequate vitamin B7 intake.

Testing for Vitamin B7 Deficiency

Blood Tests

Blood tests are commonly used to assess biotin levels in dogs. Your veterinarian can perform a blood test to measure the concentration of biotin in your dog’s bloodstream. If the levels are significantly low, it indicates a deficiency. Additionally, other blood parameters, such as liver and kidney function tests, may be conducted to rule out underlying health conditions that could affect biotin metabolism.

Dietary Evaluation

A dietary evaluation can help determine if your dog’s diet provides sufficient vitamin B7. Your veterinarian will assess the nutrient content of your dog’s food and analyze if it meets their biotin requirements. They may also consider the bioavailability of biotin from the diet to ensure optimal absorption. If any deficiencies or imbalances are identified, your veterinarian can recommend adjustments to the diet or supplementation.

Supplement Assessment

If your dog is suspected to have a vitamin B7 deficiency, your veterinarian may recommend a biotin supplement. They will assess the appropriate dosage based on your dog’s weight, age, and overall health. It is important to follow your veterinarian’s recommendations regarding supplementation to avoid overdose and ensure your dog’s biotin levels are restored to optimal ranges.

Recommended Vitamin B7 Intake for Dogs

Daily Requirements

The recommended daily intake of vitamin B7 for dogs varies depending on their size, age, and activity level. On average, adult dogs require about 70-100 micrograms of biotin per day. Puppies and lactating or pregnant dogs may have higher requirements. However, it is essential to consult with your veterinarian to determine the specific needs of your dog and adjust their diet accordingly.

Factors Influencing Intake

Several factors can influence your dog’s vitamin B7 intake. These include their diet, metabolism, and any underlying health conditions. Dogs fed a balanced and nutrient-rich diet with adequate biotin sources are more likely to meet their daily requirements. Additionally, certain medications or medical conditions may increase the need for biotin. Your veterinarian can provide guidance on how to manage these factors and ensure your dog receives optimal vitamin B7 intake.

Natural Sources of Vitamin B7 for Dogs


Liver is a highly nutritious organ meat that is rich in various vitamins and minerals, including vitamin B7. Feeding your dog small amounts of cooked liver can be an excellent way to provide them with biotin. However, it is important to ensure that the liver is cooked thoroughly to avoid any potential bacterial contamination.


Eggs are another fantastic natural source of vitamin B7 for dogs. They are readily available and can be included in your dog’s diet in various ways. Raw or lightly cooked eggs can provide biotin, but it is important to note that raw eggs may come with a risk of salmonella. Therefore, it is recommended to consult your veterinarian about the appropriate preparation method for eggs.


Salmon is not only a delicious treat for dogs but also a great source of biotin. This fatty fish is not only rich in omega-3 fatty acids but also provides vitamin B7. Adding cooked or canned salmon to your dog’s diet can help boost their biotin intake while providing other essential nutrients.


Nutritional yeast is a natural source of vitamin B7 that can be sprinkled over your dog’s food. It has a savory taste and can enhance the flavor of their meals while providing an additional biotin boost. However, it is important to choose a yeast product specifically formulated for dogs, as some commercial yeast products may contain additives that are not suitable for them.

Supplementing Vitamin B7 for Dogs

Choosing the Right Supplement

When considering supplementing vitamin B7 for your dog, it is crucial to choose a high-quality product specifically formulated for dogs. Look for supplements that contain biotin in a bioavailable form to ensure optimal absorption. Reading reviews and consulting with your veterinarian can help you make an informed decision when selecting a supplement. Avoid giving your dog supplements intended for humans, as they may contain ingredients that are harmful to dogs.

Consulting with a Veterinarian

Before starting any supplements, it is always best to consult with your veterinarian. They can assess your dog’s specific needs and recommend the appropriate dosage and duration for supplementation. They will also monitor your dog’s progress and make any necessary adjustments if needed. Your veterinarian’s expertise is invaluable in ensuring your dog’s overall health and wellbeing.

Risks of Vitamin B7 Overdose

Potential Side Effects

While vitamin B7 is generally considered safe for dogs, excessive supplementation can lead to potential side effects. Consuming very high doses of biotin can disrupt the balance of other B vitamins in the body. This can result in symptoms such as diarrhea, gastrointestinal upset, and skin irritations. It is crucial to follow your veterinarian’s recommended dosage and avoid giving your dog excessive amounts of biotin.

Consulting with a Veterinarian

Discussing any potential concerns or questions with your veterinarian is essential, especially when it comes to giving your dog any supplements. They can provide guidance on the appropriate dosage and help determine if your dog truly needs additional biotin supplementation.
