When a dog is moderately to severely injured he may shake uncontrollably. The Chihuahua breed is an 'under-the-foot' dog and can be stepped on or dropped. Trauma is the 2nd leading cause of death for this tiny toy dog. While there may not be outward signs of blood or cuts, internal injury is a possible cause for shaking. Behavior will be very off, the dog may whine or cry. He may limp or favor a certain part of the body. Any suspected cases of trauma should be evaluated by the veterinarian.
The Most Common Reasons Why a Chihuahua Shakes
Low Blood Sugar
This breed tends to have a high metabolism and is prone to dips in blood sugar levels. A minor dip can cause shaking. To avoid this, it can help to feed a Chihuahua 3 meals per day, plus snacks. Distributing the food
in this way allows the body to receive a steady supply of fuel and nutrients.
If the shaking is minor and there are no other symptoms, this can be treated by offering a healthy snack. For very young puppies, 1/4 cup of Nutrical supplement can help. Especially helpful with undersized Chihuahua, it offers a fast, additional source of energy. You can find this supplement in the Chihuahua Specialty Shoppe
If there are other signs, including: Dizziness, weakness, trouble walking, disorientation and/or excessive sleepiness, it may be a sign of hypoglycemia (a dangerous, rapid drop in blood sugar levels). This should be immediately treated at home by rubbing honey onto the puppy's gums. The pup should be brought to the veterinarian ASAP (or the closest animal hospital). In severe cases, an IV may be needed to stabilize the Chi and bring sugar levels back to normal.
This breed - due to its very small size and low fat-to-muscle ratio - has a hard time regulating body temperature. The number one reason that a Chihuahua shakes is due to being cold. And this is a shame, since many people assume that shivering is normal and therefore do not take steps to keep the dog warm.
Although you may feel that your home is at a comfortable heating level, a tiny dog such as the Chihuahua may be feeling very chilled. A Chihuahua may also feel cold when there is a rapid change in temperature, such as when transitioning from the warm outdoors to an air conditioned house or when entering a store that is colder than the temperature in the car.
A Chihuahua may have an immediate reaction and shake right away or it may be delayed. The delayed response is one reason why the cold is not considered right away as the cause. An owner may assume that since the dog has been in the same room for an hour or so, that shaking cannot be related to the temperature. However, when there is a change in environment, a dog's body will work extra hard to stay warm. At a certain point, the body will begin to fail at this.
Shivering is the body's mechanism to stay warm. When the dog's core body temperature drops, a shivering reflex is triggered. Muscles begin to shake in very small movements and this creates warmth by expending energy. An episode of trembling can be very taxing on a Chihuahua. It can be exhausting both mentally and physically.
To avoid this, keep room's warm, try to keep your Chihuahua out of drafty areas, and put clothing
on your puppy or dog. Even just a shirt or sweater will insulate the body and prevent shaking. In the winter, a heavier sweater or coat can be worn outside. When it is raining, a Chihuahua should be protected as well since a wet coat can cause a deep, penetrating cold.
