But we're both omnivores and can easily subsist on vegan diets.
That would be correct if dogs were omnivores and not carnivores http://rawfed.com/myths/omnivores.html
It may not be "natural" or traditional or even necessarily enjoyable, but we do it anyway. Is it "optimal"? In terms of both human and canine physiology
Humans evolved from apes that consumed a plant based diet while dogs evolved from a preditor and carrion scavanger. It is pointless comparing the two because there is very little to compare.
But I'd rather risk having some non-fatal health issue than deliberately choose to support the exploitation and abuse of any animals
As far as I know cancer and organ failure brought on as a result of a bad diet can be very fatal.
People have to experiment a lot before finding food their children will eat, so why do we refuse to experiment a little before giving up for dogs? If it's not fair to feed your dog a nutritionally complete and palatable vegan diet, how is it fair to feed your child a nutritionally complete and palatable vegan diet?
I would not feed a child something I knew was likely to directly bring about their death through preventable disease.
And for the record, every dog (and cat!) I've offered V-dog samples to has gobbled it up. My cat will "sit" to get a nugget of it.
I have no doubt that my dogs would lap up any antifreeze I gave them, then they would drop dead.
V-Dog's ingredients don't impress me all that much.
Wheat, Whole Corn, Soybean Meal, Quinoa and Oats Wheat Middlings, Corn Gluten Meal, Soybean Oil, Beet Pulp, Pasta, Rice, Peas, Dicalcium Phosphate, Brewers Yeast, Whole Flaxseed, Salt, Calcium Carbonate, Fructooligosaccharides, Rosemary, Parsley, Mineral Supplement (Iron sulfate, Zinc Oxide, Manganese Oxide, Copper Sulfate, Calcium Iodate, Cobalt Carbonate, Sodium Selenite), Choline Chloride, Vitamin Supplement (Vitamin E supplement, Vitamin A Acetate, Niacin, Vitamin B12 supplement, Biotin, Calcium Pantothenate, Riboflavin, Vitamin D2 supplement, Folic Acid), Mixed Tocopherols
I'd pick a different brand, personally, like Natural Balance vegan formula.
Seriously panthera I would listen to wolfie and switch because I haven't seen much worse than that. Do some research into the effects of grain, soya and salt on dogs because you'll more than likely find that this food is gonna do some harm to your dogs.
