Ol Roy dog food - Page 4

Humans and canids have completely different digestive systems.
Ours are long, theirs are short.
Theirs are far more caustic.

Humans, mice and snakes, are not dogs.

 I agree,   can't compare the impact on food between humans and dogs.  Thats why I like the Mink test so much.  they have the most similar digestive system to dogs.  able to eat "almost" rotting stuff,  grab what they need to throw the rest out before it does any harm...

My point was not comparing humans to dogs.

Humans are not mice nor snakes, but they did find similar results in raw vs cooked using these animals. There are people who cook for their dogs and I think it would be interesting to see what differeces there are.

Studies have been done with commercial feeds between dogs, foxes, mink & rats, however and I remember being surprised in how similar the rat was to a dog in digestion.

At risk of sounding sarcastic, I thought rats could survive on ANYthing, including concrete and styrofoam. That's what they're eating in my garden shed. 

Rodents aren't carnivores.  They have digestive tracts designed to consume grains.  Canids do not.
It actually requires a different stomach pH to digest carbohydrates- meaning, animals that can digest grains have a fundamentally different digestive system than does a canid.

Snakes digest their food incredibly slowly- I'm not sure we can use snakes as a model of anything that doesn't take weeks to digest its food, and is in a completely different biological class [Reptile vs Mammal]

Neither are a good comparison to a carnivore that digests food incredibly quickly [the dog].
As Oli pointed out, I conduct my own studies daily in the backyard.
I know how much crap comes out of my dog when she eats cooked food, and I know how much comes out when she eats raw food.

Clearly, she's actually digesting and using more of the raw food.

I wouldn't buy Ol Roy if I was in a one dog town and it was the last bag of food left on the gas station shelves.  IF you are a kibble feeder there are FAR better choices out there that are inexpensive and within anyones budget.

 There is one good trick I used when I had to use kibble (good quality of course)  (especially during winter)   I dosed each dish in vitamin-AD deficient fish liver oil.    Good omega-3 fats to cover them during the cold and give them that extra nourishment needed.

Just remember to have it AD vitamin removed.

A comment of fish LIVER oil, vs fish BODY oil:

Fish liver oil does contain Omega 3 fatty acids [which are important for any mammal- and our modern diet is overloaded with 6s, so we must supplement with 3s to achieve the appropriate balance], but in a form that is not very bioavailable.

In short, any Omega 3s in fish liver oil are going to end up on the lawn, so to speak.
Fish BODY oil, on the other hand, contains very bioavailable 3s.

Interstingly, horsemeat is probably the only meat that would consistently still contain the appropriate Omega 3/6/9 ratio.  If you fed a diet of primarily horsemeat, you probably wouldn't need to supplement with 3s at all.

 Mudwick,  I didn't know that.  Makes sense though.     I usually took one horse per spring,  aprox 100kg of lean meat and about 200 of assortments.   Lasted me to autumn, then I switched to AD deficient Fish oils (I know one of the biggest producers in Norther Europe,  happens to be here in Iceland).   Though the fish oils did them good,  The horse meat was always better.

 VomM,

I know that back in the day, when a fox hunter had to be destroyed s/he was fed to hounds.  It was actually something of an honor but that with the advent of euthanasia drugs that practice stopped for the very reason you mentioned.
