Why is my dog biting legs, scratching, shaking, and uncomfortable?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | neutered | 9 years and 10 months old | 15 lbs

My dog has been biting his back legs and scratching for the past couple of weeks. I have taken him to the vets to get his glands cleared also. He is now shaking and keeps moving himself so he can sit his back end against something - should I just keep an eye on this or take him to the vet?

I am sorry to hear about Alfie! Shaking and inability to sit still/get comfortable easily can be a sign of pain/discomfort so I would recommend a visit to his veterinarian for an exam. It is possible he could have some musculoskeletal pain, pain from the anal glands, or pain/irritation of the skin if his itching issue hasn't been treated. The vet can perform a good physical examination on him to help determine what is causing his discomfort and treat it appropriately.
