I've owned DODGX for a few years now, and it's been closed for a while. If you can get in, I'd say consider it as a core fund. It's a large cap that's diversified, and has a low expense ratio with decent returns. It's current 10 year average is about 14.5% and is beating the S & P average for that period by almost 6%. It holds health care, energy, materials, and financial services as it's largest holdings.
Morningstar.com is the best place to research mutual funds, and they give it a 5 star rating.
