I accidentally bought some food that was intended for "less active or overweight" dogs and mixed it with equal amounts of normal food. The less active one said 75% rdi on the back, and from what I can gather it is just the normal one but buffed up with fiber to make each serve less calories overall. I might be wrong though.
My dog is very skinny and a very active terrier. She likes to run all over the place. Would it be ok to feed her the food for a long time?
