Toxicity, Deficiency and Supplements of Vitamin D in Dogs
Vitamin D is as important for dogs’ overall health and well being as it is for people. It is involved in controlling calcium and phosphorous balance (essential for bone health, muscle function, and immunity). Good as it is for dogs, vitamin D can also be harmful — even deadly — when dogs get too much of it. Dog owners, when it comes to vitamin D, what’s most important to apply to your own life?
In this piece, I’ll look at the importance of vitamin D, the dangers of deficiency and toxicity, and how to safely add a supplement dog to your dog’s diet.
Vitamin D is a fat-soluble vitamin that plays a very important role in the bone structure as well as the immune system of dogs. Dogs do not have the ability to produce Vitamin D in their skin from sunlight as humans do; therefore the intake of Vitamin D from the diet is required.
What are the Benefits of Vitamin D for Dogs?
Vitamin D in dogs helps to:
- Strong Bones & Teeth: This vitamin supports calcium and phosphorous absorption and helps maintain healthy bones and teeth.
- Boost Immune System: Vitamin D is involved in the regulation of the immune system and thus helps to defend against infections and diseases.
- Muscle function – Controls: Correct levels of vitamin D help your muscles function and support muscle strength.
- Heart Health: It is good for the heart and circulatory system.
Sources of Vitamin D for Dogs
Most of the vitamin D in dogs is ingested in the diet. Some common sources include:
- Commercial Dog Food – A good quality commercial dog food is designed with vitamin D in the ration.
- Fatty Fish: Fish such as salmon and mackerel are loaded with vitamin D.
- Fish Oil Supplements: These are popular for increasing vitamin D consumption.
- Beef or Chicken Liver: Alongside cod liver oil, those on a liver-eating diet would be less likely to suffer from a lack of vitamin D.
Vitamin D Deficiency in Dogs
Vitamin D deficiency in canines can cause various health problems as it influences calcium and phosphorus metabolism.
Symptoms of Vitamin D Deficiency
- Weakness or lethargy
- Pain or fractures in bones
- Tremor or cramp in the muscle
- Slow growth in puppies
- Dental issues
Causes of Vitamin D Deficiency
You may develop a vitamin D deficiency if:
- Poor diet
- Insufficient absorption because of GI problems
- Some diseases of the liver or kidneys
Addressing Vitamin D Deficiency
If you’re concerned there’s not enough B12 in your dog’s life, talk to your veterinarian. They could advise on dietary changes or supplements that may remedy the deficiency. Routine blood checks may also assist in tracking and correcting vitamin D levels when required.
Vitamin D Toxicity in Dogs
It’s as important to avoid deficiency as it is to avoid too much of the stuff — vitamin D toxicity, known as hypervitaminosis D, is a serious condition that can be life-threatening.
Symptoms of Vitamin D Toxicity
- Vomiting
- Weakness
- Loss of appetite
- More urination and thirst
- Weight loss
- Bloody diarrhea
- Muscle tremors
Causes of Vitamin D Toxicity
- Over-supplementation: Administering too much vitamin D from supplements.
- Ingestion of rodenticides: Certain brands of rodenticides have very high levels of vitamin D.
- Ingestion of toxic pet food: Sometimes there is too much vitamin D in pet food, usually due to a manufacturing error.
Managing Vitamin D Toxicity
If vitamin D toxicosis is suspected, it is imperative that you seek veterinary assistance immediately. Treatment may involve:
- Stimulatin of vomiting if the dog recently ingested (locally irritating).
- Giving activated charcoal to reduce absorption
- IV fluids to help the kidneys
- Drugs to control symptoms and lower blood calcium levels
Safe Ways to Supplement Vitamin D in Dogs
Moderation is important when it comes to supplementing, as is the advice from a veterinarian.
Recommended Dosage
The right amount of vitamin D to give varies on the dog’s size, age, and health. Otherwise, it’s crucial to follow veterinary advice so that you are not exposing your pet to the risks of toxicity.
Choosing the Right Supplement
- Choose supplements made only for dogs.
- Do not use human vitamin D supplements, as the amounts in them are likely not appropriate for dogs.
- Follow third-party testing for quality and safety.
Monitoring Your Dog’s Health
This again plays into knowing how much is too much and why the regular check-ups and blood work is important, so you can monitor your dog’s vitamin D levels and make sure they’re where they’re supposed to be. Especially if your dog is on supplements or has an underlying health issue, monitoring is key.
Conclusion
Vitamin D is an essential part of your dog’s diet, providing benefits to bone health, the immune system, and more. But there can be serious effects from both too little and too much. Knowing the symptoms, reasons and solutions to a vitamin D imbalance can help you protect your furry friends. Before you make any major changes to your dog’s diet or add any nutritional supplements, always talk to your veterinarian. With the proper care and precautions, you can keep your dog healthy by giving them all the benefits of vitamin D without the potential risks.
