Actually QUITE a bit of aging can be slowed with a ketogenic diet, so the raw fed (Prey Model, esp) dogs do have quite a bit of science behind what we are seeing, as owners.

Doesn't really answer the question that the Pug used as anecdotal evidence was already a senior when he started the raw diet. So if the dog wasn't already showing a lot of signs of aging, it seems likely that the dog was lucky enough to inherit good longevity genes.
ie; if we're using humans as examples, my dad is 80 years old, and hasn't been a model of healthy lifestyle (though his girlfriend has him watching his diet a bit more, so he's lost a bit of weight). There's no mistaking him for a young man at this point, but when we walk together, he isn't any more tired from the walk than I am. I doubt anyone would take him for 80 if they didn't know that is his age. Mentally, he's sharp as ever. His parents both lived well into their 80's, and he will probably at least see 90. There is a
strong component to genetics in longevity.
Yes, epigenetics is definitely a factor in aging. I'm in the same position as you with a 70 year old mother who has six-pack abs and recently chopped down a 70 foot Maple tree her backyard, by herself. My father, on the otherhand, is an 80 year old with PD and AD. Both had similar diets, minus the copious amounts of coffee and sugar consumed by my father, but clearly there is more to aging than just lifestyle and diet.
My comment regarding ketogenic diets is an explanation of why those of us adopting mature/older dogs still seem to have amazing long-term results on Raw. IMHO a lot of this probably has to do with brain chemistry and managing inflammation. (Glucose as it is not the optimal food source for the brain, despite what scientists have previously believed. Science is an occupation of evolution, btw, and one must move with the most recent knowledge.)
We adopted Monte as a graying "mature" intact male. His dental and physical aging (skin condition and gray) put him in the ~5-7 y/o range according to 3 vets who saw him when we first got him. His current vet, who saw him then, now thinks he is 7-9, and we've had him for 6 years.
Every time we take him in for a chiro adjustment, she wants to change his age from 12ish to 7ish. I've laughed with/at her about this as she is firmly against Raw feeding and still doesn't believe in ketogenic diets. She attended vet school in the 80s and still under the belief that carbs are a good source of nutrition. (We like each other and the sparring over nutrition (and holistic medicine) and I sincerely appreciate all that she has taught me and thus contributed to Monte's health.)
These results are consistent within the circle of raw feeders I know and sadly we, with +10 y/o dogs, are now experiencing watching their non-Raw, high carb doggie friends age rapidly. Monte has lost two similarly aged PBs in the last 6 months and two other doggie friends are on a downward spiral. The PBs died of quickly spreading tumors, and the other two (Pug and lab mix) have degenerative spinal issues. All had high carb diets, with lots of treats and much love, exercise, and happiness in their lives.
(Yes, this is a small sample size, but when you expand this to the Raw feeders I know, we're all seeing the same thing.)
As you can probably guess, I'm concerned about the epigenetic issues in my family, specifically having PD on both sides. I admit I have been reading too much

, mostly nutrition and neurology journals. I am also in a doctoral program which means more research into the business of medicine. It is ugly out there, and I can only caution those under 40 to be careful about the foods they consume, the HFCS they and their children consume, and to be wary of those in science who align themselves with Big Business, profiting greatly as a result.
IMHO, along with all the industry cleaning we've experienced in the stock market, mortgage industry, and banking, we will also be facing waves of nutritional cleaning, where the links between marketing products and scientific prostitution will come to light.
The next 20 years are going to be bumpy, let me tell you! (I'm moving my money into gold, oil, and real estate...

Hyper-inflation anyone? Gotta pay off that Debt somehow, right?)
