Y eah, its true. Some vets don't get it that dogs are carnivores, descended from the Gray Wolf (Canis Lupus). Some vets are so conditioned they cannot think outside the milieu. They unquestioningly believe all they are told.
I watched a video talk by Professor Seyfried on cancer. In the talk he relayed a story of a lady who cured her dogs cancer tumour, by taking her dog off manufacturers dog food and feeding it raw meat. The vet was surprised the dog lived and phoned Professor Seyfried to get more info. The vet retorted he could not give dogs raw meat.
There appears to be some doubt whether dogs are carnivores or omnivores. Go take a look at rawfed.com website, where any doubt about a dogs ancestry and dietary habits are covered in detail and with great clarity. Including links to supporting evidence from those in the know.
Purina are pet food manufacturers, part of the transnational Nestle Corporation. On their website, they have a dog food marketing page that asks the rhetorical Are Dogs Omnivores Or Carnivores?
The following is taken from same web page:
1.) A BALANCED DIET FOR DOGS INCLUDES GRAINS
Many people believe dogs are carnivores. In fact, dogs are omnivores, and even wolves in the wild derive nutrition from both plant and animal sources.
2.) GRAINS ARE NUTRITIOUS
When you look at the research, the evidence stacks up that grains are nutritious and effective for your dog.
3.) WHEN WE FORMULATE OUR FOODS, WE START WITH NUTRIENTS, NOT INGREDIENTSTo counter this marketing hype and lies:
We look for positive results to make sure our formulas benefit real dogs' health, digestion, energy-levels and ability to live a happy, healthy life. When we formulate our products, we don't start by prioritizing ingredients that are popular. Instead, we study the nutrients that dogs need, and then look to nature for the best ingredients to deliver on them.
1.) In fact, dogs are carnivores.
2.) Grains are not effective nutrients for a dog. Dogs need meat.
3.) Nutrients would be meat, not grains or plant derivatives.
Its unreal that a major corporation with a few shreds of respectability would lie outright or even bend the truth to suit their sales and marketing needs. I guess it happens all the time. Money talks.
I've owned many cats since I was a kid, some died at an early age. Going back years, an acquaintance said the manufactured cat food was killing them. I didn't get it back then. I didn't understand. Naive and lacking life experience, I shrugged and continued to feed my cats, manufactured tinned cat food. Mostly cos it was convenient, and honestly, I didn't know any better. I can't say with any certainty, the tinned cat food killed the cats, and I can't say it didn't. But I certainly didn't feed my carnivores, a meat diet.
Does the carnivore pictured right look like he would enjoy an omnivorous vegetarian pizza washed down with a fruit smoothie! I guess not.
Go have a look at rawfed website. There's a lot of honest explicit info on feeding your carnivores.
