Improving Canine Health with Vitamin D for Dogs

After conducting decades of research on vitamin D - and publishing numerous academic papers - Dr. John Cannell has brought his well-known vitamin D formulation to the animal kingdom!

Because dogs cannot synthesize vitamin D from the sun like humans, Dr. Cannell believes a vitamin D supplement may be even more important for dogs than for humans. So, over the course of the past few years, Dr. Cannell worked to perfect a vitamin D formulation that offers the optimal dose for our canine companions.

However, in efforts to promote DoggyD's vitamin D to the public, we've realized we want to turn DoggyD into a general research hub for dog owners.

Ultimately, we aim to share the latest research on canine health topics, including vitamin D for dogs and beyond.
