If your dog has been showing a change in behavior and you’re wondering Why is my dog shaking and breathing heavily? In order to determine what steps you should take next you should first figure out how long your dog has had these symptoms. To begin with you should ask yourself how long has my dog been acting this way? 

If your dog shows these symptoms for a long period of time you should consult your veterinarian and get your dog checked out for any underlying diseases or medical issues.

Is it an emergency?

Mans best friend is a dog so are you also thinking is this an emergency?

Dogs know us like no one else and though they cannot talk they communicate with us in their own way. Whenever your dog shows any signs of shivering or trembling ask yourself if they have done this before and have they shown this behavior after they were shocked?

Could there be a reason your dog may be shocked? As with us dogs can become shocked and show symptoms such as panting shaking and trembling. Different factors can lead to shocks such as trauma or an accident. If you believe your dog is in a state of shock take the appropriate steps to calm him down.
