This is my first BT. Shae is now 12 weeks and i've had her for 1 month. What i'm wondering is she gets these little bumps on her head that when you scatch across flake off like dry skin. My husband thinks they are flea bites but we have had the flea medicine put on her at the vet that last for a month and it has only been a couple weeks. We have never saw a flea on her either. Someone told me that these dogs have really dry skin. Could this be what it is and what can I do about it...?
