It's also ok to disregard manufacturer's recomendations for the amounts of feeding your dog. I've found them always to be rather generous in their estimates. You might want to play around with how much you give her to determine her particular needs.
Personally, I think the manufacture has a vested interest for a dog to be over fed.... more dog food is purchased :D Sometimes, I wish they would make things a little easier & give the caloric rating along with the rest of the info. I think it would help in comparisons between brands. Just a thought anyway.
