My dog took fish oil with vitamin D. Is 1000 IU safe for a 110 lb dog?

Updated on September 23rd, 2025

my dog was just diagnosed with arthritis and the vet recommended fish oil vitamins. I gave him one about an hour ago and just saw that it also contains 1,000 iu of vitamin D. I read that too much vitamin D is very harmful for dogs will he be ok??? he weighs about 110 pounds.

The amount that he ingested is not considered toxic. Calculated, he ingested approximately 0.025mg of vitamin D and toxic doses for this size of a dog would potentially start at 5mg. He will be absolutely fine! I would recommend fish oil products such as welactin or Krillex krill oil treats.
