If your dog is shaking, then chances are you are concerned about your dog's health. This article will cover some of the potential reasons for why your dog may be shaking, but it is no substitute for professional veterinary advice. If you are at all in doubt, contact your local vet.
There are several reasons your dog may be shaking, mostly due to the dog's health. You may be able to identify relative factors from the list below to explain your dog's shaking.
Dogs have fur coats that let them stay warm at temperatures lower than humans are comfortable, so if your dog is shaking due to the temperature, chances are you are as well. Turn up the temperature or give your dog a blanket and see if your dog stops shaking.
Dogs can feel stressed and anxious just as humans can. Certain events may scare dogs, like fireworks or thunder, because they are unable to understand what is happening. If you can't control the source of the anxiety, simply talk to your dog, stroke it and try to provide some sense of comfort and relief until the stressor passes.
Your dog may be shaking as it is in pain. Dogs can't communicate pain to us very well, so just because they're not whimpering or limping doesn't mean they're not in pain. The dog's health is important, so err on the side of caution if you can't find another explanation.
In all cases where an obvious explanation cannot account for your dog's shaking, take your dog to the vet. The dog's health is important and you often can't know how serious the reason for shaking is.
