According to PetMD, dogs exhibit trembling and leg tremors when they have a medical condition or are anxious. Additionally, some dogs have a genetic predisposition to uncontrollable tremors.
According to WebMD, puppies who exhibit trembling in their legs or other places and are not fully vaccinated may be suffering from distemper. The symptoms of distemper include coughing, fever, and a runny nose. Antibiotics, hydration with fluids, airway dilators, and physical therapy are used to treat distemper.
Certain dog breeds are susceptible to shaking due to GTS or General Tremor Syndrome. WebMD and PetMD explain that GTS primarily affects Maltese, West Highland terrier, Chow Chow, Dalmatian, Doberman pinscher, English bulldog, Samoyed, Labrador retriever, and springer spaniel dogs between the ages of nine months and two years. This condition is treated with corticosteroid injections.
Young dogs also have tremors after ingesting a toxin, such as a plant. Another cause of shaking is nausea. WebMD suggests searching for additional symptoms of nausea, such as salivation, fatigue, lip smacking, and vomiting. When these symptoms are evident, owners should seek emergency veterinary care immediately.
There is not always a discernible cause for leg tremors. If a dog is typically healthy, eats a balanced diet, and there is no evident explanation for a violent reaction, the shaking could be a physical quirk. Consult a veterinarian for the most accurate diagnosis of limb shaking.
