I was feeding our Toto the Natural Balance roll and Royal Canin Yorkshire 28 dry and she began to leave most of her food. Our vet suggested that I add a little vegetable so I started giving her the Gerber Graduates [baby food] carrots and green beans along with the Natural Balance. She loved them and finally began eating just the veggies!

I discussed this with our vet and she said it was OK if all she wanted was her veggies so I began cooking fresh carrot, green bean, potato, etc. with no seasoning. I added a little garlic powder, parm cheese or sour cream to the veggies. She absolutely loved it and before I knew it was 2 lbs. overweight!!

Now she is on a diet of 1/4 cup Nutro Ultra and about 1 tablespoon of the RC per day and I can't seem to get the weight off this little "porker"!
In answer to your question about veggies ... Toto much prefers veggies and I believe the weight gain could possibly be her lack of exercise. My only concern about the veggie only regimen was that she possibly wasn't getting the proper nutrients. I still give her a few veggies but only if she will eat the Nutro along with them!
