It can be concerning to see your dog shaking. While it’s easy to dismiss trembling as just a sign of aging, or simply your dog being cold, shaking can actually indicate a range of underlying health issues, some of which require immediate veterinary attention. Understanding the potential reasons behind your dog’s tremors is crucial for ensuring their well-being. If you notice your dog shaking, especially if it’s a new symptom or accompanied by other changes in behavior, it’s always best to consult with your veterinarian.
One common reason for shaking in dogs, particularly older dogs, is pain. Let’s explore some of the potential causes of why your dog might be shaking:
Arthritis and Joint Pain
Arthritis is a degenerative joint disease that is very common in senior dogs, and it can be a significant source of pain. This pain can manifest as trembling, especially in the legs. You might notice your dog shaking more after they’ve been lying down for a while or after exercise.
Fortunately, arthritis pain in dogs can be managed effectively. Your veterinarian can recommend a variety of treatments, including:
- Supplements: Glucosamine and chondroitin supplements can help support joint health and reduce inflammation.
- Medications: Pain relievers and anti-inflammatory drugs, like NSAIDs, can provide significant relief.
- Other therapies: Physical therapy, acupuncture, laser therapy, and weight management can also be beneficial in managing arthritis pain and improving your dog’s comfort and mobility.
Poisoning and Toxins
Another serious cause of shaking in dogs is poisoning. Dogs are curious creatures and sometimes ingest things they shouldn’t. Many substances that are harmless to humans can be toxic to dogs and cause tremors or shaking. Some common culprits include:
- Chocolate: Chocolate contains theobromine, which is toxic to dogs. Dark chocolate and baking chocolate are especially dangerous.
- Cigarettes and Nicotine: Nicotine is highly toxic to dogs and can be found in cigarettes, e-cigarettes, and nicotine gum.
- Xylitol: This artificial sweetener is found in many sugar-free gums, candies, and even some peanut butters. Xylitol is extremely poisonous to dogs and can cause a rapid drop in blood sugar and liver failure.
- Snail Bait: Snail baits containing metaldehyde are highly toxic and can cause severe muscle tremors, seizures, and even death.
Symptoms of poisoning in dogs can be varied and may include:
- Tremors and shaking
- Weakness and lethargy
- Disorientation and incoordination
- Depression
- Excessive drooling
- Nausea and vomiting
- Diarrhea
- Seizures
If you suspect your dog has ingested something poisonous, it’s crucial to act quickly. Contact your veterinarian immediately or call the Animal Poison Control Center (ASPCA) at (888) 426-4435. Prompt action can be life-saving.
Seizure Disorders and Epilepsy
Seizures are another neurological condition that can cause shaking and tremors in dogs. Epilepsy is a common seizure disorder in dogs. During a seizure, your dog may exhibit a variety of signs, including:
- Collapsing
- Jerking and involuntary movements
- Muscle stiffening
- Twitching
- Loss of consciousness
- Drooling or foaming at the mouth
- Chomping or tongue chewing
- Paddling motions with their legs
Epilepsy can often be managed with medication. Common anti-seizure medications for dogs include:
- Keppra (levetiracetam)
- Phenobarbital
- Potassium Bromide
If you suspect your dog is having seizures, it’s important to consult with your veterinarian to get a proper diagnosis and treatment plan.
Canine Distemper
Distemper is a serious and contagious viral disease that can affect dogs, particularly puppies and unvaccinated adolescent dogs. Tremors are a common symptom of distemper in dogs. Other signs of distemper may include:
- Discharge from the eyes and nose
- Fever
- Coughing
- Lethargy
- Vomiting and diarrhea
- Seizures
- Paralysis in later stages
Treatment for distemper is primarily supportive care, as there is no cure for the virus itself. Supportive care may include:
- Antibiotics to treat secondary bacterial infections.
- Airway dilators to help with breathing difficulties.
- Physical therapy to manage neurological symptoms.
- Fluid therapy to combat dehydration.
Vaccination is crucial in preventing distemper. Ensure your puppy receives the full series of distemper vaccinations and that your adult dog receives booster vaccinations as recommended by your veterinarian.
Generalized Tremor Syndrome (GTS)
Generalized Tremor Syndrome (GTS), also sometimes called steroid-responsive tremor syndrome or white shaker dog syndrome, is a condition characterized by full-body tremors. While it was initially observed in small, white dog breeds like Maltese and West Highland White Terriers, GTS can affect dogs of any breed, size, and color. The exact cause of GTS is currently unknown.
GTS is often treated with corticosteroids like prednisone. Many dogs respond well to steroid treatment, and the tremors can be significantly reduced or eliminated. However, long-term management may be necessary.
When to See a Vet
While some causes of shaking might be benign (like being cold or excited), it’s essential to be aware of when shaking could indicate a more serious problem. You should consult your veterinarian if your dog is shaking and exhibits any of the following:
- New or worsening tremors
- Tremors accompanied by other symptoms like vomiting, diarrhea, lethargy, or loss of appetite
- Seizures
- Suspected poisoning
- If the shaking is persistent or interferes with your dog’s normal activities
In conclusion, shaking in dogs can stem from various causes, ranging from arthritis pain to serious conditions like poisoning, seizures, distemper, and GTS. As a loving dog owner, being observant of your dog’s behavior and seeking veterinary advice when you notice concerning symptoms like shaking is paramount. Early diagnosis and treatment can significantly improve your dog’s health and quality of life. Always err on the side of caution and consult with your vet if you are concerned about your dog’s shaking.
