    The Vitamin D toxicity concerns have been known since before November 5.

    Today is December 3.

    “At doses as low as 0.1 mg/kg, we can start to see signs of vitamin D poisoning.”

    Symptoms of Vitamin D toxicosis can be seen with doses as low as 0.1mg/kg, and a lethal dose in a mature dog can be as low as 2mg/kg

    Yet another problem that should have been found by testing prior to any product being shipped out-
    “Nutrisca became aware of the elevated levels of vitamin D after receiving complaints from three pet owners of vitamin D toxicity after consuming the product. An investigation revealed a formulation error led to the elevated vitamin D in the product. ”

    I find it very concerning that my King Soopers (Kroger company) had Abound Chicken and Brown Rice Recipe Dog Food on sale and ONLY that flavor in Abound. This was the first week of November. Almost like they knew but was trying to push it as not to lose profits. I will never buy dig food from the Kroger store again as long as I love. How can I trust them after a stunt like I witnessed? I can not. Dies this mean their human food should also be looked at?

      Very little human food contains vitamin D in sufficient quantities to result in optimal levels; we evolved to manufacture vitamin D in our skin. On days when your shadow is never shorter than your height, you should supplement with vitamin D3. At my latitude of 49 degrees, I take 10,000 IU vitamin D3/day during the winter. Some recommend taking approx 1000 IU/11kg/day. The medical establishment recommends far less. See .

    We need to know what the actual vitamin D levels in the suspect foods are. Even though toxicity signs may begin to appear at a dose of 0.1 mg/kg, which is 4000 IU/kg, the vitamin D LD50 is vastly higher. The 8.5 kg dog described in the report at may have ingested ~200,000 IU vitamin D (23,529 IU/kg) which resulted in a serum 25 hydroxyvitamin D concentration only marginally above the normal reference range. The report of four dogs at showed that 10 mg of cholecalciferol/kg (400,000 IU/kg) resulted in hypercalcemia and hyperphosphatemia and then death; this is a massive dose that would normally only be attained by ingesting a rodenticide. Interestingly the study at suggests that low concentrations of 25(OH)D may be a risk factor for congestive heart failure. The question is how many dogs die as a result of too little vitamin D compared to too high?
