Why Is My Dog Shivering & Vomiting?
Shivering can indicate a variety of fairly minor problems for dogs, such as being cold, anxious or frightened -- nausea can even cause dogs to shiver. However, shivering also can indicate serious problems, such as poisoning or kidney disease, especially when it accompanies vomiting. Therefore, you always should seek veterinary assistance whenever vomiting accompanies shivering.
Whenever shivering and vomiting appear suddenly, you must seek immediate veterinary care as it may indicate that your dog has eaten something poisonous. If it is feasible to do so, check the area in which your dog spends time to see if you can determine any obvious signs of poisoning, such as a displaced trashcan. Many common substances, including chocolate, cigarettes and sugar-free gum, can be very toxic to dogs. Bring anything you suspect your dog ate with you to the vet. Snail baits are particularly toxic, and they cause muscle tremors and shaking in dogs.
Kidney Disease and Distemper
Unfortunately, kidney disease often fails to produce symptoms until it is at an advanced stage. Accordingly, it is important to observe your dog vigilantly for warning signs, such as unquenchable thirst and frequent urination. While it does not always cause vomiting, canine distemper also can cause dogs to shake violently. Because most older dogs already have been vaccinated against distemper, it is most likely to afflict dogs between 2 and 6 months of age.
