Thanks for using Petco Pet Education Center, formerly Petcoach! This is likely due to mouth pain. This may be due to bone discomfort or perhaps any sort of fracture or trauma. It could also be due to muscle pain. I recommend that you have her evaluated by a veterinarian for further assessment and treatment. They would be able to check for these possibilities and treat accordingly. Good luck and have a great day!
