Thank you for using Petco Pet Education Center, formerly Petcoach! Missy engaging in nipple sucking could be a behavioral change, but it could also be due to underlying discomfort associated with that nipple/mammary gland. Scheduling a visit with Missy's veterinarian would be beneficial to get a good palpation of the mammary glands associated with the nipples she is sucking to make sure there are no masses palpable. If she receives a clean bill of health, then it could be a behavioral change she is exhibiting.
