Why is my old dog wobbly, shaking, and having head tremors?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | neutered | 13 years and 5 months old | 20 lbs

Since yesterday, Charlie has been kinda wobbly. He sometimes walks like he's drunk. Yesterday morning, he was laying on the couch with his head up but his head kept making rhythmic movements and from side to side. He's also been somewhat restless lately but when he finally gets comfortable, he sleeps very deeply. He is 13 1/2 years old and has had a lot of health issues in the past including parvo, distemper, and getting bit by a rattlesnake. His back legs also involuntarily shake.

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Charlie. He could have many things going on due to his age. Possibilities include toxin exposure, infection, heart problems, neurologic problems, endocrine/hormone problems, kidney/liver/gallbladder disease, cancer, etc. I would advise taking Charlie to your veterinarian right away to get him assessed. Your vet can gather a history, perform an exam and then advise a diagnostic/treatment plan based on their findings. Possible tests include fecal/blood/urine tests, x-rays/ultrasound. Once a diagnosis is made a treatment plan can be implemented. Good luck with Charlie
