Hopefully someone here can let me know how much I should worry. I took Sheila in for her 12 week vacinations and exam this morning. It all went well exept when the vet examened her he found a small hole at the top of her skull. He seemed concerned but not overly so saying that she is still so young that there is a chance it may fill in? Has anyone here had any experience with this? I can feel it now, it's like a tiny indent in her skull. I've had her for a month now and I've grown too attached to give her back to the breeder

. Any advice is most welcome.
