Why Does My Dog Shake When He Eats?

Your dog shakes for all kinds of reasons when he eats. Thus, you cannot put your finger on only one reason. Some dogs even tremble while they are breathing. Trembling or shivering can be related to a larger health issue, or it can simply be one of the behavioral patterns of your pup. 

If your dog shakes specifically when he eats, we don’t think it is a problem, but if it continues shaking for the rest of the day, then it might. However, to remove any doubts, you should meet your vet and ask for his advice and opinion on the matter. 

Even so, we have researched and compiled the following reasons that support your dog’s shaking when he eats. Check them out below


While it might be weird or rare for a dog to shake in excitement when eating, it is not unheard of. Food makes your pup happy, and they express their happiness in several ways – maybe it’s his way to exhibit this emotion when he eats the food. Shaking can be a form of adrenaline release in dogs.

Fear or anxiety 

Even though this emotion is the complete opposite of the first one, it can still trigger your dog to shake or tremble while eating

It can be because the place you feed them is too noisy or disturbing for them, or they have an attached trauma to it or eating food. It can be anything from fighting with other dogs for food or hearing an uncomfortably loud noise while eating.

Shaker Syndrome 

Also known as white dog syndrome, shaker syndrome usually occurs in dogs 1 to 4 years of age. This syndrome usually affects small-sized dogs and can cause them to tremble, shake, even have seizures. It also makes them lose balance, lack coordination, or collapse. It is important to get medication for this problem and help your puppy live a happier and healthier life. 


Shaking is one of the many signs of distemper disease, in which discharge from the eyes, lethargy, and fever are quite frequent. 

Distemper diseases usually affect wild animals like skunks and raccoons, but they can be transmitted to dogs as well. It is best to prevent your dog from having it by getting him vaccinated, or it can also be fatal. 

Generalized Tremor Syndrome

Some smaller breeds of dogs like Chihuahuas just shake, it has no real reason behind it. This is known as GTS.


If your dog shivers while eating, consider moving him to a warmer area and see if the trembling disappears. This could be a very simple and obvious reason why the poor guy is shaking. Fever can also cause shaking.

If your dog exhibits a reflex movement or feels threatened or excited and shakes, you must hug him and make him feel loved during the moment, and you will see the dangerous behavior disappear instantly. 

However, if the movement continues for several days, let’s say about a week or so, we recommend you go ahead and see a vet and follow his guidelines.

Why Is My Dog Shaking After Shots?

It could be because they have developed a fever or it is just a side effect of the shots.

Shaking and shivering is one of the common side-effects of vaccinations, and it is perfectly normal for your furry friend to feel this way. According to experts, distressed shaking results from pain and inflammation at the injection site. 

It is especially the smaller breeds of dogs that shake after being vaccinated. It is also possible that your little friend might get a high fever or feel unwell due to vaccine effects. It is, in fact, a good thing since it is a sign that your dog’s immune system is responding to the shot and is starting to produce antibodies.

Another reason for your dog shivering and shaking after taking shots is the stress he goes through while handling the injection and all the poking that comes with it. Some dogs are more sensitive than others, and thus, this is their way to release anxiety and stress of vaccination or even visiting the vet’s office.

A little shaking is a sign that everything is fine with your pet, but if it continues for days and is accompanied by vomiting or an upset stomach, you must call your vet and book an appointment with them to further get into the matter.
