Hi, welcome to yorkie talk. Drooling can be a sign of nervousness. Has your 4 year old been around other dogs before? Just be very careful having him around the puppy until you know how he will react to the puppy. Is your other puppy a male or female?
A helpful hint: When you need help or have a question it is best to start a new thread. I noticed that your other post was added to an older thread so it is getting overlooked. Best of luck with your new puppy.
