Why is my dog suddenly scared, running, circling, and shivering?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | unspayed | 6 years and 9 months old | 45 lbs

My CC is a mut, her mom was a rot, dad was a mut with a Shepard mix an coyote and unsure of others, she’s 7-8. Lately she’s been acting quite erratic I have her being a companion for a old lonely friend. But visit often. She keeps a reg diet of Diamond naturals chicken. Her behavior consists of spontaneous running from one end of the house to the other circling, acting like something is after her, and occasionally shivering. Unless I work to distract her. Any help would be appreciated.

WIthout actually seeing the behavior it is difficult to say exactly what is going on with her. I would recommend taking a video of this behavior and making an appointment with your veterinarian to have them view the video and determine if this is something to be concerned about. Thank you for using Petco Pet Education Center, formerly Petcoach.
