Proud coddler here!
Very proud coddler here as well!
Unfortunately, I have not had great health success with my dogs. Possibly due to where they came from (pet stores -> puppymills) and possibly food they ate.
I got my first dog, a maltese in the early 90's. She passed away at 11 years old. She suffered from terrible allergies, bad cataracts and cushing's disease. At like 8 or 9 years old, she acted more like a dog who is 15. She was on what was is now considered low-quality food most of her life. Later in her life, we did switch to what we thought was better quality food. My second dog and my first sheltie was overweight and had early arthritis. She passed away from a heart-condition at only 8 years old.
We got my next dog, a maltese again, when I was in my late teens. I started looking more into food quality and breeders. She is from a breeder and not a pet store, but I would consider the breeder more of a backyard breeder. This dog will be 12 years old in May. She is nothing like my first maltese. Other than having a low-thyroid (managed with meds) and allergies (resolved by changing foods), she looks great for her age! She gets the zoomies every time I see her (she lives with my parents). Based on her appearance and energy, you'd think she was 5 years old.
After the heartache I felt with seeing my first two dogs suffer from health ailments, I knew I wanted my next sheltie to have the best life possible. I wanted a dog that will live a long & healthy life. For me, that starts with going to a reputable breeder, feeding high-quality food and providing good healthcare. Will my girl, who is almost 5 now live as long and as healthy as I hope? I don't know, but I'm going to set her up by giving her every chance possible. That is why I do look at ingredients and heavily research dog food quality and nutrition. I will do the same exact thing when I plan to have a baby. I don't think this is overreacting or coddling. I was raised to always question things, never settle. I like to be an informed person and consumer. I like knowing what I'm putting in my or others' bodies. You only get one chance at life, why not try to make as best as you possibly can?
As to what is "good dog food", like others have stated, I think that is different for every dog. My dog had bowel issues every time I tried Wellness, but my parents' dogs are thriving on Wellness. I don't think Wellness is bad food, just didn't agree with my dog. I think Ann's post best explains how I feel about finding good dog food. Good luck! It can certainly be a bit of trial and error.
