So basically it doesn't matter what body type I put him at is that correct? So whether he's emaciated or overweight it isn't going to change his calorie count or intake unless I change his activity level correct? So basically the whole body type is a useless?
Body Score is not useless. You know that if you are ideal, then you are giving the right amount of calories. If he is emaciated then you need to up the calories, likewise you lower the calories if he is overweight.
If your dog is emaciated, then let the body score reflect that. You will be able to play around with the activity level to up the calorie count.
Let me know if you need help with this.
