Ellie used to eat Science Diet and I thought she was doing well on it.
Her nose was dry most of the time.
She had a rough patch of fur.
And she threw up every week or two for no reason.
I thought these things could be normal until I switched her to something else.
Well, those things aren't normal and she doesn't really have those issues anymore.
I'm sure all dogs react to it differently.
So,

on Science Diet.
If I had to feed kibble I MIGHT be willing to try the Nature's Best though.
