Good morning, well, it's morning here. :-)
I assume everything checked out at the Vet's office. Did he check thyroid, just in case your dog is hypothyroid? That being said, she should be on a good brand of weight management, adult food. Look for the feeding recommendations on the product to see how much to feed, I assume she probably wouldn't need more then a cup or a cup and a half twice a day.
You can try the old dog show people green diet. You get green beans (low sodium) and feed half the normal food with half green beans until you get to or near the desired weight.
Limit treats or feed carrots, if your dog will eat them.
I suspect that most of your dog's problem is from Improper nutrition.......Pedigree is one of the lowest quality foods on the market...Purina is about as Bad! I consider both to be "Death In a Bag".....Actually, the bags they come in are healthier than the food enclosed!
With a higher quality product that is NOT mainly cheap, un-nutritious fillers, fattening carbohydrates (Grains), chemicals, by-products, and cancer causing agents, your dog will begin to shed some pounds....
Links to address this food problem & look into healthy Pet Foods:
You can add fresh fruits & cooked veggies to her bowl, daily....These will help fill her up & are highly nutritious & low fat, while you start cutting back on her regular food......
This needs to be done slowly since she is not use to real food......The weight will be coming off before you know it.....Keep up with the walks......Good luck, this CAN be done! Your doing the right thing to get weight off of her now while she's young.........Karla
