Fda Recalls A Number Of Dry Dog Food Products Causing Vitamin D Toxicity
More brands have been added to the administrations list of pet foods containing dangerous amounts of vitamin D.
The problem of vitamin D toxicity in dry dog food may be bigger than expected.
The U.S. Food and Drug Administration is adding another recall to its initial two, following an investigation that found elevated levels of vitamin D in a number of goods.
According to the FDA, this is a developing situation and additional recalls may be announced.
New reports indicate the goods come from a manufacturer that makes products marketed under several different brand names.
The administrations scientists are currently analyzing all information available to determine whether the illnesses are definitively connected to diet. Samples of some of the products were evaluated and test results indicated the food contained as much as approximately 70 times the intended amount of vitamin D.
Consuming food with high levels of vitamin D is potentially toxic to dogs, and in severe cases may lead to kidney failure and/or death. It can also cause vomiting, loss of appetite, increased thirst, increased urination, excessive drooling, and weight loss.
The FDA encourages veterinarians treating vitamin D toxicity to ask their clients for a diet history. Vitamin D toxicity may also present itself as hypercalcemia, similar to when dogs consume rodenticide, the administration warns.
When Does Supplementing Become Dangerous
One supplement in your dogs diet probably isnt going to be enough to cause harm to your furry friend. Its when owners provide one supplement for their eyes, one for their liver, one for their joints, and one for good measure, supplementation becomes dangerous.
Thats why its important to find a supplement that has everything your dog needs for bio-replenishment. Vetericyn offers the All-In supplement for exactly that reason. All-In offers dogs a supplement that is:
- Age-specific Puppies and senior dogs dont need the same nutrients. Supplements should address the age of the dog to give them what they need when they need it.
- Gut-friendly Probiotics and prebiotics are necessary for a healthy gut biome. This biome is responsible for everything from the proper absorption of nutrients to your dogs mood to their physical wellness.
- Good for joint health Puppies bones are rapidly growing senior dogs bones are decaying. Both need vitamins and minerals targeting joint health to ensure a happy and healthy life.
- Antioxidative Antioxidants remove the free radicals from your dogs cells which slows down the aging process.
With a single supplement, you dont have to worry about hypervitaminosis turning toxic. Moderation is built right in.

So What Is The Right Amount Of Vitamin D For Dogs
Nutritionists affirm that there should be about 500IU of vitamin D per kilogram of pet food. For larger or older dogs, the amount can go up to 1000 IU per kg of dog food. If your dog is getting vitamin D in the amounts of 500-1000 IU, you will never worry about the furry fellow every getting sick.
One problem though, not everyone is a fan of metrics. We may not always get the measurements right especially when the days get busier for us. Fortunately, you only need to know the right sources for vitamin D for your dog.
If you do not trust store-bought pet food, you can always rely on raw dog food for your dogs rich source of vitamin D. Ensure you are getting the concentration of calcium and phosphorus in the pets food. Your dog will never suffer vitamin D deficiency in its life.
If accessing fresh raw dog food is a challenge, then stick to store-bought kibble with the right vitamin D content. Consider the age and size of your dog to determine how much vitamin D content they need in their food. Younger dogs like puppies will need a high amount of vitamin D, say 1500IU per pound of food, to develop healthy bones. Mature dogs need about 500IU of vitamin D while older dogs will need more to keep their bone mineral density at a healthy level.
How Much Vitamin D Does A Dog Need
According to the Association of American Feed Control Officials, dogs should have around 500 IU of Vitamin D for every kilogram of dog food. In the form of supplements, it should not be more than 100-120 ng/ml of Vitamin D per day.
Like many of us, almost all domesticated dogs these days dont have a lot of time outdoors. This means the main source of Vitamin D3 for them only comes from foods. Its risky to give Vitamin D to dogs without your vets consent. The only way to find out if your dog needs a supplement is by having him examined. Your vet should perform a blood test to determine if the vitamin levels in the blood are low.
Its important to be aware of the proper dosage because Vitamin D can be poisonous to dogs if ingested in unrestricted quantities. The signs to keep an eye out for with Vitamin D poisoning are too much drooling, pain in the stomach, vomiting, inappetence, sudden loss of weight, and lethargy.
If you suspect your dog ingested more Vitamin D than he should have, call an animal poison control center or better bring him to the nearest veterinary hospital.

Do Dogs Need Vitamin Supplements
Your dog gets his vitamins from dog food. Commercial dog food diets labeled complete and balanced are specially formulated to contain all of the vitamins, minerals, and nutrients your dog needs.
Foods catered toward different life stages, like puppy food, adult dog food, and senior dog food, contain different levels of certain vitamins, depending on the requirements of that life stage. This is especially important for large breed puppy foods, as these breeds can develop diseases, such as hip dysplasia, if their food contains vitamins and minerals, like calcium, that make them grow too quickly.
Dogs fed an appropriate commercial diet should not require vitamin supplements unless recommended otherwise by a veterinarian. Dogs fed a homemade diet, on the other hand, may require supplements to ensure that they are getting enough vitamins with their meals. However, these vitamins should be given to match the diet, according to veterinary nutritionist Susan Wynn, DVM. Simply feeding these dogs a vitamin with dinner is not enough.
What Happens If My Dog Gets Too Much Vitamin A

Diagnosis Of Vitamin D Poisoning In Dogs
As the symptoms of vitamin D poisoning overlap with many other conditions, it is important to disclose details about your dogs diet, any supplements you have been adding, and if your dog may have been able to access rodenticides or another source of vitamin D recently. Being able to determine that vitamin D poisoning is causing your dogs symptoms will aid in a swift recovery.
The veterinarian will conduct a complete physical examination, and conduct a complete blood count, which checks for abnormalities in red and white blood cell count. Additionally, a blood biochemistry profile will measure levels of calcium and phosphorous, elevated levels of which indicate vitamin D poisoning. The biochemistry profile may also show lower than normal levels of potassium and an accumulation of nitrogenous waste products, as well as low levels of albumin and high levels of certain liver enzymes. A urinalysis will be conducted to measure levels of proteins and glucose, which, if elevated, will help confirm the diagnosis. In some cases, an echocardiogram will measure your dogs heartbeat, as some dogs suffering from vitamin D poisoning have slowed heartbeats.
What Care Is Required After Treatment
Unfortunately, the effects of vitamin D poisoning can last many weeks to months. Blood work to monitor calcium, phosphorous, and kidney function are typically recommended following discharge from the hospital. If elevations in calcium, phosphorous, or kidney values occur, monitoring may need to be continued for many weeks. Some dogs may require further hospitalized care since calcium levels may increase again following initial treatment. Kidney damage may occur in dogs that develop high calcium levels. They may require long-term management for kidney failure including blood work monitoring, fluid therapy, anti-nausea medications, medications to control blood pressure and antacids.

Increasing D Levels By Improving Digestion
Dr. Howell recommends feeding dogs a variety of meat-based diets that are free from corn, wheat, soy, rice, white potatoes, tapioca, and peas. Those foods are alkalizing to the stomach, and dogs need an acidic stomach for food to be digested and nutrients like vitamin D to be absorbed. The other problem with these ingredients is that they cause inflammation, which decreases nutrient absorption. As animals age, their stomachs become more alkaline, which explains why older animals may have a harder time breaking down and absorbing Vitamin D from their food.
For dogs fed dry food, she suggests adding bone broth or warm water before feeding. Adding raw organic apple cider vinegar to food helps acidify the stomach, she adds, and it provides prebiotics, which feed gut microbes. Add 1/8 teaspoon to each meal for small dogs 1/4 teaspoon for dogs weighing 21 to 50 pounds and 1/2 teaspoon for dogs more than 50 pounds.
WDJ contributor Mary Straus, whose dogaware.com website offers nutrition and feeding tips, recommends supplementing the diet with probiotics , prebiotics , and digestive enzymes to improve digestion and the assimilation of nutrients.
Coconut oil and butter contain saturated fats and are often listed as good companions to fat-soluble vitamins. Consider adding 1 teaspoon per 25 pounds of body weight to your dogs dinner to help improve his or her vitamin D levels.
