I interviewed the president of V-Dog Food in May 2009 about his kibble, the benefits of the vegan diet for dogs, and myths on the subject. David mentions vet Dr. Armaiti May.
In the video David also mentions that they'd have new products by the end of this year. I recently followed up with him and he said: "we still plan on introducing these new products, and we hope to raise the required capital this year to accomplish this". In other words, if you support the company enough they'll be able to make new products!
