I remember our dogs when I was a kid living long and healthy, barely seeing a vet. I don't remember the dog food that was fed, lots of table scraps for the bigger dogs, but I'm sure it was junk. However, I am starting to wonder if all this new fangle "healthy" food along with all the vaccines, heartworm/parasite meds, etc is what is really causing more health issues and shortened lives. I hate giving heartworm meds now. Monthly I'm poisoning my dog with medication for other parasites she doesn't have just to prevent heartworm. Now even in Chicago, they want you to give it all year. I was a vet tech years ago, I know the game.When I was a kid, we had a TEACUP TOY POODLE that just about lived forever at 17 years. All she ever ate was MIGHTY DOG from a can. Half a can each evening.
That and Milk Bones for snacks.
