Crystal is right. My vet just tells me to get the flavorless just in case the pups don't like it. The cherry is fine though. You may want to put an e-collar or doughnut pillow around her until you can get her to your vet. She may not like it, but it can prevent her from scarring herself and sometimes the hair doesn't grow back fully
I've seen a lot of Yorkies with bad skin problems. I remember Bailey pretty vividly. Poor guy was just a sheet of scabbed skin and nearly bald from itching himself raw. So sad...
