It’s a common assumption for many dog owners to dismiss tremors or shaking in their aging dogs as simply a part of getting older. However, while age can play a role, trembling in dogs can also signal underlying health issues, including pain. If you notice your dog trembling, especially if it’s a new symptom, consulting with your veterinarian is crucial. This guide will explore the common reasons behind why dogs tremble, helping you understand when these shakes might be a cause for concern.
Arthritis and Joint Pain
Arthritis is a significant cause of pain, particularly in older dogs, and this pain can manifest as trembling. The discomfort and inflammation in the joints can lead to involuntary shakes, especially in the legs. Thankfully, veterinary medicine offers various treatments to manage arthritis pain and joint inflammation. These can range from joint supplements and pain medications to other therapies designed to improve your dog’s comfort and mobility.
Toxin Exposure and Poisoning
Several toxins and poisons pose a serious threat to dogs and can induce tremors or shaking. It’s alarming to note that some substances harmless to humans can be highly toxic to our canine companions. Common household items like chocolate, cigarettes (leading to nicotine poisoning), and xylitol, an artificial sweetener found in many sugar-free gums and candies, are all potential dangers. Additionally, snail baits containing metaldehyde are extremely hazardous and can cause severe muscle tremors and convulsions in dogs.
The symptoms of poisoning in dogs are varied and can include not only tremors but also weakness, disorientation, depression, excessive drooling, nausea, vomiting, diarrhea, and even seizures. If you suspect your dog has ingested something potentially toxic, immediate action is vital. Contact your veterinarian without delay, or reach out to the Animal Poison Control Center at (888) 426-4435 for expert guidance.
Seizure Disorders and Epilepsy
Epilepsy, a neurological disorder, is another reason why dogs tremble. Seizures, a primary symptom of epilepsy, can present in several ways. You might observe your dog collapsing, exhibiting jerking or stiffening movements, muscle twitching, loss of consciousness, drooling, chomping their jaws, chewing their tongue, or foaming at the mouth. During a seizure, dogs may fall to their side and make involuntary paddling motions with their legs. Fortunately, epilepsy in dogs can be managed with medications designed to control seizures. Common treatments include medications like keppra, phenobarbital, or potassium bromide, prescribed by your veterinarian to help regulate brain activity and reduce seizure frequency and severity.
Canine Distemper Virus
Distemper, a viral disease, predominantly affects puppies and adolescent dogs that haven’t completed their vaccinations. It is a well-known cause of tremors in dogs. Beyond tremors, other signs of distemper include discharge from the eyes and nose, fever, and coughing. Treating distemper typically involves supportive care, allowing the dog’s immune system to combat the virus. Treatment strategies may also incorporate antibiotics to manage secondary bacterial infections, airway dilators to help with breathing, physical therapy, and intravenous fluids to combat dehydration.
Generalized Tremor Syndrome (GTS)
Generalized Tremor Syndrome, also known as steroid-responsive tremor syndrome or sometimes referred to as white shaker dog syndrome, is another condition associated with trembling in dogs. Initially recognized in small, white dog breeds like Maltese and West Highland white terriers, GTS can affect dogs of any breed, size, or coat color. The exact cause of GTS remains unknown, making diagnosis and treatment focused on managing the symptoms, primarily tremors, often through the use of steroids.
Understanding why dogs tremble is the first step in ensuring their well-being. While some causes are linked to aging, tremors can also be a critical indicator of underlying health issues that require veterinary attention. If you notice your dog trembling, don’t hesitate to consult with your vet to determine the cause and the best course of action for your furry friend.
