If your dog has just been for a swim or has gotten wet out on their walk, they’ll shake themselves to get rid of the excess water. In this case, shaking is completely normal and is actually good for your dog as it can help to prevent hypothermia.
They can remove up to 70 percent of the water from their fur just by shaking – which is why you’ll end up soaking wet if you’re in the splash zone.
2. Stress or fear
Do dogs shake when scared? Yes - dogs may also shake due to stress or fear, which is most commonly seen at the vets or when fireworks are going off. Dog trembling may also be paired with signs like whining, whimpering, growling, panting and they may pin their ears back and hide.
If they seem anxious quite often, it’s a good idea to monitor any possible triggers that make them feel that way. Then, if possible, remove these triggers from their lives, or consider enlisting the help of a dog behaviourist.

3. Excitement
One of the possible reasons why a dog keep shaking is excitement. Your dog shaking can happen when they’re playing with you, if you’ve just got home and they’re happy to see you or if you’re just about to go for a walk. When dogs shake due to excitement it helps to lower their excess energy and keep them more contained. Most commonly it’s seen in younger dogs as they tend to have weaker impulse control, and it’s usually a good idea to pay less attention to them until they calm down, then reward them with a calm stroke.
4. Cold
In a similar way to how we shiver when we’re cold, dogs also do this. Some breeds are more sensitive to the cold than others, particularly if they’re smaller or have a thinner coat, as they have less protection from the elements. If the cold really seems to bother them, invest in a coat and maybe even a pair of booties to keep them toasty during the winter.
If your dog seems to be shivering for a long period of time, take them to the vet as it could be a sign that your dog has hypothermia.
5. Old age
Sometimes dog trembling is due to old age. It’s not unusual for this to occur as they get older, however sometimes too much shaking could be a sign of pain and in particular joint pain. If this is the case, take them to the vet as soon as possible and they will be able to suggest how best to help your dog.
6. Muscle weakness
Muscle weakness can also be a cause of shaking or trembling. This will usually be displayed as their legs shaking – particularly their rear legs. Generally, this will resolve when they’ve had time to rest, but if this seems to be bothering your dog, take them to your vet and they may suggest exercises to strengthen their muscles, or treatment like massage or hydrotherapy.
