My fat dog

Also I wouldn't feed the amount they tell you to on the bag, most of the time they tell you to feed waaaay more than you should.

Exactly; that's why they're called guidelines

If she is gaining weight then feed LESS than what you were currently feeding. If she is losing weight, then feed more. As you've already said you've adjusted, but don't worry if you aren't feeding her enough!

Try a "lite" dog food, such as Nutro.

I have a lab/chow mix that was up to 60 pounds. The vet thought she should be at least 10 pounds lighter. So I switched her to Nutro Lite, measured her dinner (2 level cups a day) and added a few green beans. It took a year, but she's now down to 52 pounds. The only treats she gets are one small, inch and a half biscuit in the morning and one snausage at night. I tried carrots, but she won't touch hem.

Just remember that your dog didn't get 'fat' overight and it'll take a while to safely get the extra weight off.

My first thoughts were thyroid too. If your not feeding too much and getting plenty of exercise this could be the culprit.
It's an easy test and doesn't take long. I'd get to the vet and see what he has to say.
