My dog's legs jerk when relaxing. Could it be restless leg syndrome?

Poor pup. Muscle twitches in a pet so young can be caused by a toxin ingestion, a metabolic imbalance (i.e. Low calcium), an underlining neurological disorder, or it can just be a sign of pain somewhere in the body. If the muscle twitches are happening for more than a few hours then it is best to take Chevy to you nearest veterinarian for a complete neurological examination so that he receives the appropriate treatment. At the very least they can give him muscle relaxers to help with his symptoms and then any pain medication he may need. I hope your puppy gets well soon. Best wishes and good luck at the vet.

Hi! Thanks for entrusting us with Bentley's care today! Lameness and/or possible leg pain and shaking can be a sign of a few things that range from a muscle sprain to even a fracture. I recommend that you have him evaluated by your veterinarian so that this can be further assessed which will likely include radiographs. Treatment will be dependent on findings though at the very least pain control medications can be prescribed. Good luck! Hoping for a speedy recovery!

Although the leg doesn't seem painful by far the most common cause of the shaking you're describing would be a leg injury or arthritis. I would recommend having your vet examine Rook's leg. They might recommend taking an x-ray, especially if Rook is stoic during the exam as well.

Muscle tremors in the back legs can be a sign of pain, anxiety, or a neurologic problem. It's difficult to know if the injections might be related without knowing exactly what they were. If the tremors are the only symptom and your dog is not walking normally and does not seem painful you might be safe to monitor this weekend and see your vet when they open. If your dog is weak, having trouble walking, appears painful or has other symptoms like a decreased appetite or vomiting I'd recommend seeing an emergency veterinarian.

It could be that Ruby overexerted herself during her walk tonight, and now she is feeling a little bit of pain causing her to be in discomfort. You can try gently rubbing her legs if she will let you to see if that helps, or putting some heat in the form of a heat pad (not too hot!) to see if that helps relaxes her muscles. Do not give her any human pain medications, as many are toxic to puppies and can be fatal if given. As long as she is otherwise normal (i.e. eating and drinking normally, went to the bathroom normally, isn't limping or appears to be in pain), then I wouldn't be too worried about her just yet. Hopefully she will settle down soon. Best of luck, I hope this helps!

Most likely it is not related to anything and is only incidental. However, this can only be confirmed after a physical exam by your veterinarian. If it persists or worsens, I would suggest a check up to assess if there is any sign of [elbow dysplasia](https://www.petcoach.co/dog/condition/elbow-dysplasia/), [panosteitis](https://www.petcoach.co/dog/condition/panosteitis/) or other condition/injury, as pain can cause shaking in dogs.

So your dog has arthritis in the right hip and a subluxation in the left hip. He may be shaking due to pain from these problems, and he may need pain medications. Do NOT give him any human pain medications. Many are toxic to dogs and can be fatal if given. Take him into the vet to get pain medications. Best of luck.
