Shaking or quivering in dogs can be concerning for pet owners. While sometimes it’s just excitement or cold, other times it can signal a more serious underlying health issue. Understanding the potential causes can help you determine when it’s time to seek veterinary care.
Common Reasons for Quivering in Dogs
Several factors can contribute to dog quivering, ranging from benign to serious:
Pain and Discomfort
One of the most common reasons for trembling, especially in older dogs, is pain. Conditions like arthritis can cause joint inflammation and discomfort, leading to noticeable shaking. Your veterinarian can diagnose and manage arthritis with medications, supplements, and other therapies to alleviate pain and improve mobility.
Poisoning
Ingestion of toxic substances can trigger tremors in dogs. Many household items, seemingly harmless to humans, pose significant dangers to pets. Chocolate, cigarettes (containing nicotine), xylitol (a sugar substitute in gum), and snail bait with metaldehyde are common culprits. Symptoms of poisoning vary widely but can include tremors, weakness, disorientation, drooling, vomiting, diarrhea, and seizures. Immediate veterinary attention is crucial if you suspect poisoning. Contact your vet or the Animal Poison Control Center (ASPCA) at (888) 426-4435 without delay.
Seizures
Epilepsy, a neurological disorder, can cause seizures in dogs, characterized by jerking, stiffening, muscle twitching, loss of consciousness, drooling, foaming at the mouth, and paddling motions with their legs. Treatment typically involves anticonvulsant medications like Keppra or phenobarbital to manage seizures and improve quality of life.
Distemper
Canine distemper, a viral infection primarily affecting unvaccinated puppies and young dogs, can manifest as tremors. Other signs include eye and nose discharge, fever, and coughing. Treatment focuses on supportive care to bolster the immune system while the dog fights off the virus. Antibiotics, fluids for dehydration, and physical therapy may also be necessary.
Generalized Tremor Syndrome (GTS)
GTS, also known as steroid-responsive tremor syndrome or white shaker dog syndrome, can affect dogs of any breed or color, though initially observed in small white dogs. The cause of GTS remains unknown. Treatment often involves corticosteroids to manage tremors.
When to Worry About Dog Quivering
While some quivering is normal, consult your veterinarian if:
- Tremors are severe or persistent.
- Accompanied by other symptoms like vomiting, weakness, or difficulty breathing.
- Sudden onset with no apparent cause.
- Your dog is acting unusual or distressed.
Early diagnosis and treatment are essential for managing underlying health conditions and ensuring your dog’s well-being. Regular veterinary checkups and open communication with your vet are crucial for proactive healthcare.
