Why is my senior dog shaking, pacing, and panting all night?

Updated On September 23rd, 2025

Pet's info: Dog | Jack Russell Terrier | Female | spayed | 13 years and 5 months old

My 14 year old Jack did not eat dinner and began shaking, pacing and panting last night at 9pm. She did this nonstop until 7:30am this morning. She has acted this way when there were fireworks nearby but it only lasted for a short period. What could have caused this and should I take her the vet although she is no longer acting this way. She is sleeping now.

Thank you for submitting your question regarding Noel. I do recommend that she sees a veterinarian today. She could be painful somewhere that was causing her to pant and pace. Neck and/or back pain are common in small breed dogs. If this is not the cause, nighttime anxiety can develop in older dogs. It is similar to the anxiety experienced by human Alzheimer's patients. It would be best to have her seen so you can both get some sleep to tonight. I hope this information helps!
