My rottweiler doesn't like to be pet very often. is this normal?

Yes, it's normal for some Rottweilers, or any dog, to have their own preferences when it comes to physical affection. Each dog has a unique personality, and some may be more independent or sensitive to touch. It's important to respect their boundaries and interact with them in ways they are comfortable with. If your dog shows signs of discomfort when being petted, it's wise to give them space and find alternative ways to bond, like playing or training.
