What kinds of things can cause my dog to shake?

Generally, a dog will shake if he/she is stressed or fearful. Try to remove the cause of stress/fear. There are more serious reasons such as hypothermia, hyperthermia, hypoglycemia, seizures and more. Get your dog to a veterinarian immediately to find the cause and get treatment.

There are several different reasons why a dog might shake. Nervousness, stress, anxiety, excitement, sore muscles, strokes, seizures, overheating, because they're too cold, they're in pain, etc. are all reasons why a dog might shake. It's important to figure out the reason, as knowing the reason will give you the opportunity to best help your dog. Does she usually shake before or after walks? When she's exposed to new situations? When something scary happens like a thunder storm? Is it accompanied with panting? If your dog pants continually, it can be a sign that they're in pain. If you suspect your dog is in pain, it's important to get her checked out by the vet so that you can help her feel good again.
