It can be concerning to see your dog trembling or shaking. While it’s easy to dismiss these tremors as just a part of aging, especially in older dogs, trembling can signal a variety of underlying health issues, some of which require prompt veterinary attention. If you notice your dog shaking, it’s important to consider the possible reasons and when it’s time to seek professional help.
Common Causes of Trembling in Dogs
Several factors can contribute to trembling in dogs, ranging from manageable conditions to more serious medical emergencies. Here are some of the common causes:
Arthritis and Pain
Arthritis is a frequent culprit behind tremors, particularly in senior dogs. The pain and inflammation associated with arthritis can cause dogs to tremble, especially in their legs. Fortunately, veterinary medicine offers various ways to manage arthritis pain and improve your dog’s comfort. Treatments can include joint supplements, pain medications, and therapies designed to reduce inflammation and enhance mobility. Addressing the pain of arthritis can significantly reduce trembling related to this condition.
Poisoning and Toxins
Exposure to toxins or poisons is another serious reason why your dog might be trembling. Many substances that are harmless to humans can be highly toxic to dogs. Common household items like chocolate, cigarettes (leading to nicotine poisoning), and xylitol (an artificial sweetener found in sugar-free gums and candies) are dangerous for dogs. Additionally, snail baits containing metaldehyde are extremely toxic and can cause severe muscle tremors and convulsions in dogs.
Symptoms of poisoning in dogs are varied and can include not only tremors but also weakness, disorientation, depression, excessive drooling, nausea, vomiting, diarrhea, and seizures. If you suspect your dog has ingested something poisonous, immediate action is crucial. Contact your veterinarian immediately or call the Animal Poison Control Center at (888) 426-4435 for guidance.
Seizure Disorders (Epilepsy)
Epilepsy, a neurological disorder, is a condition that can cause seizures in dogs, which often manifest as trembling and shaking. Seizures can present in various ways, including collapsing, jerking movements, muscle stiffness, twitching, loss of consciousness, drooling, chomping or tongue chewing, and foaming at the mouth. During a seizure, a dog might fall to their side and exhibit paddling motions with their legs.
Managing epilepsy typically involves medication to control seizures. Common medications include Keppra, phenobarbital, and potassium bromide. If you observe seizure-like activity in your dog, it’s imperative to consult with your veterinarian to get a proper diagnosis and start appropriate treatment.
Canine Distemper
Canine distemper is a viral disease that primarily affects puppies and adolescent dogs that have not been fully vaccinated. Distemper is a known cause of tremors in dogs. Alongside tremors, other signs of distemper include discharge from the eyes and nose, fever, and coughing.
Treatment for distemper is mainly supportive, focusing on managing the symptoms while the dog’s immune system fights the virus. This can include antibiotics to prevent secondary bacterial infections, airway dilators to help with breathing, physical therapy, and intravenous fluids to combat dehydration. Vaccination is key in preventing this serious disease.
Generalized Tremor Syndrome (GTS)
Generalized Tremor Syndrome (GTS), also known as steroid-responsive tremor syndrome or white shaker dog syndrome, is another cause of trembling in dogs. Initially observed in small, white dog breeds like Maltese and West Highland White Terriers, GTS can affect dogs of any breed, size, or color. The exact cause of GTS remains unknown, but it is characterized by tremors throughout the body.
When to See a Veterinarian
While some causes of trembling might be benign, it’s always best to err on the side of caution. If your dog starts trembling, especially if it’s a new symptom or accompanied by other signs like vomiting, lethargy, or disorientation, it’s crucial to consult with your veterinarian. Prompt diagnosis and treatment can address underlying issues, alleviate discomfort, and ensure your dog maintains a healthy and happy life. Don’t hesitate to reach out to your vet when you notice your dog trembling – it’s always better to be safe and informed when it comes to your pet’s health.
