Thanks for using Petco Pet Education Center, formerly Petcoach! This is just part of the more typical behavior for a dog and the way they tend to respond to cats. If this becomes an issue and she is becoming aggressive towards your kitty, I would encourage you to contact a local qualified dog trainer who can work with you in person as most of these behaviors can be improved with in person training and time. Good luck and have a good night!
