Why does my puppy's leg tremble when he's sitting or lying down?

Updated on September 23rd, 2025

Pet's info: Dog | Pit Bull Terrier | Male | unneutered | 3 months and 16 days old | 25 lbs

His left leg shakes while he sits or lays down its like a trembling shake. But it doesn’t hurt him if we grab it or touch it.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. If you have done a thorough check of his leg and are finding nothing wrong with Chief and he is walking on the leg just fine, I would monitor this for now. I have seen this in quite a few puppies and when I examined the puppy further, I found nothing wrong and it resolved on its own. If Chief begins to show signs of pain / discomfort, I would recommend having a veterinarian examine him so that the most appropriate diagnostic and treatment recommendations can be made. It looks like Chief is about 12 weeks of age, so at this age he still needs to go through the remainder of his puppy vaccinations. At his next vaccination appointment, I would discuss this further with the examining veterinarian. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
