My 8 year old Frenchie has got this horrible skin problem. Been to vet and got Cortisone and had antibiotics, not helping. Now we just started Apoquel 5.4mg to see if it will help her. Hair is just falling out. We have switched to all grain free food /treats. Skin scraps were fine. Keeping her indoors and not out with bugs. She does not itch or lick anywhere. Any help will be very much appreciated. Anita
