Hi, thanks for using Petciach. I'm having a hard time understanding your question. I think you are saying that you have a 9 week old Chihuahua puppy that has a aoft spot in the top of it's head? It could be an open fontanel and hydrocephalus. Here is an article about it. Please let us know if that is not what you were asking https://vcahospitals.com/know-your-pet/hydrocephalus-in-toy-breed-puppies
