Lots of things to consider when selecting a dog food such as does the dog have any known/suspected allergies, do you want grain inclusive or grain-free--and what price range do you want to be in? (just to name a few).
dogfoodadvisor.com has a list of most dog foods and rates them from 1-5. (5 being what they consider best, 1 least). Not every dog requires a 5 star food to do well and not all 5 star foods are the most expensive.
Personally, I stay in the 4-5 star range and I avoid corn/soy/wheat in all foods because I do have a golden with some allergies. Some foods that I feed and/or would feed to my dogs are:
These are also broken down by lowest price to highest price category--at least for my area:
Chicken Soup for the Dog Lovers Soul
Taste of the Wild
Hope this gives you a start. Welcome and good luck!
Just as a general guideline, make sure to read those ingredient labels, and stick with a food that has a meat meal rather than a plain meat as the first ingredient(unless it's wet food), plain meats can come after the meals. Avoid foods with ambiguous or "mystery" meats and by products(ex: meat by-product meal, poultry-by product meal, bone meal, etc) meats should be specified(turkey meal, chicken fat, lamb, beef heart)also avoid corn, wheat, and soy.
Here are a few, any of these would be good choices, you should be able to find one that works well for your dog.
