Hi and Welcome to the forum! Wow, new to poodles and you are jumping in with both feet, huh? Congratulations on both of your poodles. Give us details (until you can post photos, of course). What size are they? Names, ages, colors, etc. As far as your girl's dry flakey skin, I think you should rep-evaluate after a while of feeding her quality food and giving her good brushing and grooming. She may not have a problem at all except being fed poor quality food.
