That's awesome. I love it!
People will disagree, but there is really no such thing as a "high quality" factory processed pet food, only more expensive and successfully marketed.
Most pet foods are heavily grain based and really not digestible for a dog, this is why there is such a volume of poo from pet food fed canines. Some claim to not use grain, and some of these ones are even being honest in that regard. Some do use real meat in their brand of pet food, but this is always meat that has not been passed for human consumption because the animal was either diseased, dying, dead, or even decomposing.
The nutritional values listed on a can of pet food can just as easily be derived from a leather boot, can of motor oil, and various other bits of rubbish you'd never knowingly or willingly feed your self, your family, or your dog. Some countries, not all, even use ground up deceased pets from animal mortuaries and vets' offices in pet foods that are fed to the same kind of animal, but now I'm getting off track so let's get back to the poo we all love so much - lol.
Sloppy dog turds are generally always a the result of a pet food diet, a raw meat and bone diet mostly results in firm and drier droppings that turn chalky white in the sun far before the pet food variety, and even better, they simply crumble under foot so you don't have to worry about the turd you just stepped in.
The slight aroma of Natural Diet Doggy Doodoo, even when fresh out of Rover's back side, is nowhere near enough of a stench to clear a crowded elevator.
A Pet Food Poo on the other hand, even when disturbed after a week out in the whether, could empty a sports stadium (slight exaggeration but you get my drift).
People will state quite adamantly and at times accurately that their pet food fed dog's leave quite acceptable bodily excretions. This is generally because that pet food fed dog also has a good supply of raw meaty bones to clean the teeth and gums. What we have then is a dog with strong pearly white teeth, a hybrid mix of deceptive defecations, and still suffering internally from the indigestibles in all brands of factory processed pet food which our pet food company founded vets constantly recommend so the vicious cycle of Periodontal Disease and organ failure that stems from it, keeps the veterinary wallet over flowing and the same in turn for the pet food companies.
I'm making no effort to guilt-trip fellow dog owners/dog lovers, but I do make an effort to raise awareness and guilt-trip pet food companies and veterinarians.
Granted, the question was merely "Why does dog poo smell?" but why give a half informative un-researched answer when a little digging gets you a long way?
Now I am sure, here come the disagreements...
Of course you're going to get disagreements, because what you're saying is kind of absurd. No way can you lump all commercial foods together, nor can you state with any accuracy how a given diet is going to affect all dog's poop. I mean, why even claim that? It's so silly.
For example, here are the ingredients in Ol' Roy dog food. Pretty crappy:
Ground yellow corn, meat and bone meal, soybean meal, chicken by-product meal, wheat middlings, animal fat [preserved with BHA and citric acid], natural flavor, brewers rice, salt, calcium carbonate, potassium chloride, choline chloride, color added [red #40, yellow #5, blue #2], zinc sulfate, vitamin E supplement, ferrous sulfate, zinc oxide, niacin, copper sulfate, vitamin A supplement, biotin, manganous oxide, calcium pantothenate, vitamin B12 supplement, thiamine mononitrate, pyridoxine hydrochloride, menadione sodium bisulfite complex [source of vitamin K activity], riboflavin supplement, sodium selenite, calcium iodate, folic acid, vitamin D3 supplement, cobalt carbonate
ON THE OTHER HAND, here are the ingredients in Orijen dog food. Pretty freakin' good:
Fresh boneless salmon, salmon meal, herring meal, fresh boneless herring, fresh boneless walleye, russet potato, sweet potato, peas, salmon oil (preserved with mixed tocopherols), fresh boneless lake whitefish, sun-cured alfalfa, fresh boneless flounder, fresh boneless northern pike, pea fiber, organic kelp, pumpkin, carrots, spinach, turnip greens, apples, cranberries, blueberries, licorice root, angelica root, fenugreek, marigold flowers, sweet fennel, peppermint leaf, chamomile, dandelion, summer savory, rosemary, vitamin A, vitamin D3, vitamin E, niacin, thiamine mononitrate, riboflavin, calcium pantothenate, pyridoxine, folic acid, biotin, vitamin B12, zinc proteinate, iron proteinate, manganese proteinate, copper proteinate, selenium yeast, Lactobacillus acidophilus, Enterococcus faecium
You can continue treating pet foods like they're all comparable if you want, but you're just going to make yourself look foolish. People here aren't stupid. The facts are easy to find and they just don't add up with what you are claiming.
Obviously people should feed the best they can BUT that doesn't ALWAYS mean raw and IME it hardly ever excludes high-end commercial pet foods. How is it not obvious to raw food groupies and anti-pet food zealots that this sort of talk is HURTING your message and certainly not helping any dogs.
