Dogs and cats, just like people, are living longer than they ever have. The dog next door is almost 20 and has always eaten commercial food. My last dog made it to almost 15. We had to feed him ground turkey, rice and eggs, because of a genetic condition.
My current dogs, both five, eat mostly commercial food, Wellness. We tried the raw diet for many months and they hated it. It made my one dog puke all the time.
I think people like to worry about everything.
The last 3 generations of dogs (Labs and retrievers) I’ve had have been fed Purina One with great results. My vet asks me every time I take them in for vaccinations what I feed them (trying to push the pricey Eukanuba). They have bright eyes, shiny, healthy coats, plenty of energy and absolutely no health problems whatsoever. They get supplemented with raw carrots, broccoli, corn, when our garden is producing, along with whatever else they forage on their own, like the occasional rabbit or squirrel. My oldest is going on 12 and you would think she’s a young dog the way she acts. The mere mention of the work “hike” sends her into a tizzy. My next door neighbor feeds her dogs the same and she had one Walker coon hound live to be 19 and an American Eskimo live to be 21.
My dog ate commercial food out of a bag and it finally killed him after 15 years.
That's a worrisome comment.
