A trembling dog, especially on the hind legs, can be influenced by various factors such as muscle fatigue, overuse or cold.
Additionally, emotional factors such as stress or medical causes, such as cramps, can be the cause.
In some cases, the shaking can also be a sign of more serious health problems, such as stomach problems or poisoning.
Why do dogs tremble on their hind legs? - 5 main reasons
It's important to keep a close eye on your dog's behavior and consult a veterinarian if symptoms persist or cause concern.
Overexertion and cramping:
When a dog plays intensely or is active for long periods of time, he expends a lot of energy and puts a lot of strain on his muscles. This can cause him to feel overexerted, much like a human after an intense workout. The result of this over-commitment can be trembling of the hind legs, which can be a sign of muscle fatigue or tension. Additionally, an overly engaged muscle may cramp. Cramps are often painful and can be exacerbated by the tremors. In addition, if the dog becomes unresponsive to its owner, this may be a clear sign of a cramp or other serious disorder. In such situations, it is important to have the cause investigated by a veterinarian and allow the dog sufficient recovery time.
Cold Sensitivity:
Every dog is different, and while some dog breeds with thick coats already have the cold protection built in, there are others, especially those with short or thin coats, that are more susceptible to cold. These dogs can freeze quickly, which can cause shivering throughout the body. A warming piece of dog clothing, such as a coat or sweater, can help keep the dog's body warm, reducing shivering. It is important to be aware of the climatic conditions and protect the dog accordingly.

Stomach problems, muscular problems and exhaustion:
Dogs, especially larger ones, can be prone to stomach problems. Signs may include increased salivation, vomiting or unusual body language. In addition to stomach problems, older dogs may develop shaky legs due to muscle wasting and general weakness with age. Muscle fatigue and weakness can also occur in younger dogs, especially after intense activity. It is important to monitor the dog's physical activity and ensure that he is not overworked.
Emotional stress:
Just like humans, dogs can suffer from emotional stress. Loud and sudden noises, such as thunder or fireworks, can trigger anxiety in many dogs. Trembling is the body's natural response to stress or anxiety. Aside from trembling, dogs may also show signs of restlessness, panting or excessive barking. Homeopathic remedies, such as Bach Flower Remedies or special sedatives, can help alleviate the dog's stress and calm him down.
Toxin exposure:
A dog's curiosity can sometimes become dangerous, especially if he eats or ingests something toxic. Symptoms of poisoning can be varied, but tremors are a common sign. Other symptoms may include vomiting, diarrhea, shortness of breath or loss of consciousness. If a dog shows signs of possible poisoning, it is important to seek veterinary care immediately. Acting quickly can be life-saving. It is advisable to keep potentially poisonous substances and plants out of reach of dogs.
A shaking dog can have a number of causes. It is important to identify the cause in order to help him effectively. When in doubt, it is always advisable to consult a veterinarian.
