If your puppy seems distressed or in a problem,  talk to a vet about your pup’s condition.

Why the puppy’s front leg is shaking?

To start,  this could be nothing and your puppy will be fine on its own.


you can’t ignore if you are observing constant trembling in the leg. Puppy front leg shaking could be due to weaknesses in the brain, a result of genetic diseases, or tremors.

We have made a list of possible reasons and Puppy front leg shaking could be due to one of these

  • Old age
  • Front leg deformity
  • Tremors
  • Stress
  • Low sugar levels
  • Fatigue
  • Nervousness
  • Genetic disease
  • Injury
  • Obesity

Now one by one we will try to understand how these reasons could affect your pup’s movement.

Old age

Have you noticed old people with trembling hands? And how Parkinson‘s affects their motor abilities. Brain diseases are a major cause that affects the movements of body parts. The root cause of every motor ability dysfunction is linked to the brain somehow. The brain gives commands to the whole body to function properly.

In old age,  the brain functions of your dog get affected as it does in all living beings ( this is what aging is for). Body parts start trembling due to the weak connection between the brain giving the signals and body organs receiving them.

Front leg deformity

In front leg deformity, one leg can grow more than the other one causing limping in dogs. This condition could be inherited or due to premature closure in the growth plate and is very painful for dogs. An injury in the legs can also cause front leg deformity.


Tremor is a disease where body parts shake during movement. Puppies can develop tremors at any age and many puppies are even born with this disease.

The dogs born with tremors may show symptoms within a month of their birth. A puppy learns to start walking and holding its balance three weeks after birth. So any trembling or shaking will be visible within the first few weeks. Talk to the vet for further treatment of your dog.

Infection /disease

A viral infection called a distemper can cause a leg shake. This viral infection has appeared to be fatal and affects different organs of the body. Distemper can target the digestive,  respiratory and nervous systems as well, affecting motor abilities.

Diarrhea,  vomiting,  lethargy, and shaking legs could be the symptoms of distemper. We also understand that these symptoms are common in other diseases too. Your dog gets distemper from another infected dog. So talk to your vet for further examination of your puppy.

Stress/emotional trauma

Stress affects brain muscles and thus can be linked to shaking movement patterns. Your puppy can be stressed due to many reasons and some of them could be so simple that you might overlook them.

Calming down your puppy will stop the shaking movements. Sometimes trembling could be due to fear also which is another variant of stress and emotional trauma. So make sure that the puppy is well pampered not only physically but also emotionally. Mental health is as important as a physical one. Never take it lightly.

Low sugar level

The low sugar level in the bloodstream can cause weakness and shake in body parts. Your puppy will also feel lethargic if the blood sugar is below the level.

A simple and effective remedy is,  give your puppy something sugary to eat. Also,  talk to your vet about adding supplements to your dog’s diet for additional nutrition. Don’t stress out your dog and try to keep giving him food in portions. Long fasting could also result in dropped sugar levels.


Fatigue is another reason that affects motor abilities. Fatigue usually accompanies other symptoms so observe carefully. A set of particular symptoms could be a sign of underlying disease.


Nervousness is common among dogs and this can cause shaking in the legs. Nervousness is like spontaneous stress on the brain. You don’t need to worry if your puppy’s leg is shaking due to nervousness. This trembling will go away soon.

Genetic disease

Some puppies are born with Hypomyelination which is also called shaking puppy syndrome. This disease affects the central nervous system of dogs. Tremors could be a result of shaking puppy syndrome.


Shaking movement in legs could be due to injury or bone disorders as well.  Maybe your pup has fractured its leg or is suffering from elbow dysplasia. Front leg shaking could mean your puppy is in pain. You need to talk to your vet to confirm.


When you feed your dog too many calories,  obesity can cause trembling in the legs while standing or sitting. In simple words, a dog’s legs are unable to support its weight.

So if your puppy is obese and has front leg shaking while sitting, you need to increase exercise and playtime. Take your puppy on long walks and give him tough exercises to lose more calories and stay fit.

What to do if your puppy’s front leg is shaking?

Mostly,  there is nothing serious and you can treat the problem on your own. For example, if it’s a reflex movement or your puppy is scared,  you need to hug and calm your puppy and soon he will be fine as ever. But if you notice other symptoms along with trembling front leg, book an appointment to vet and take professional help.
