: 家裡狗狗的這個情形大概有快半年
: 如同前面所說 狀況時好時壞
: 之前比較好的時候 以為已經康復 但之後又出現這樣的情形
: 出現咳嗽的時間點不固定
: PS.家裡狗狗13歲.算是有點年紀了...不知這樣的狀況是否也和年紀有關
: PS2.飲食方面我們也算頗注意.平常只餵飼料
當然需要帶去動物醫院。

情況是不是和妳家狗狗情況很類似，不過因為它處在亢奮狀態，次數比你的狗狗快。
從症狀來看，最有可能是因上呼吸道的阻塞而導致，尤其是氣管塌陷(collapsing trachea)
的可能性很高，在作進一步的檢查前，必須先試著把病畜穩定下來，安置於安靜而且涼爽的
環境，避免過度運動。
氣管塌陷容易發生於許多小型品種的犬隻，例如吉娃娃、博美犬、迷你貴賓犬和其他迷你品
的犬種，這易發犬種大部份都是屬於先天性，也有少數因為長期呼吸道的感染，造成氣管本
身彈性的消失，導致氣管塌陷。具有這種體質的犬種於二歲以前通常不致有什麼問題發生，
隨年齡的長大氣管的彈性越來越差，塌陷的情形也越來越嚴重。因為氣管狹窄的關係，氣體
通過氣管時會有類似鵝鳴的呼吸聲，如果有感染同時存在，不論是急性或慢性的感染，將會
引起嚴重的咳嗽症狀。可能伴有氣管炎的情況，她的呼吸聲後有作咳作嘔的動作，且同時發
出ㄎㄚ\的聲音。
體重的控制是管理上最重要的因數，過重的犬隻常有嚴重的症狀外同時伴有心肺疾病，藥物
治療包括鎮咳劑，支氣管擴張劑和預防及對抗細菌感染的抗生素。假如藥物無效就必須進行
外科療法。
除此之外你可以觀察有無以下症狀，咳嗽，呼吸困難，吸入性呼吸困難，呼吸急促，乾嘔，
黏膜發紫，心律不整。建議你，明天就找時間帶他去動物醫院，你可以提供這段影片給醫生
看，作為參考。看診回來，可以寄信和我分享看診結果嗎 ? ^ ^

Collapsed Trachea
Race Foster, DVM

Collapsing trachea (or collapsed trachea) is a common condition that causes
coughing in small and toy breeds of dogs.
Let us start with an explanation of how the dog breathes, The respiratory
system is basically comprised of the opening in the nose, the sinuses, the
larynx (air passage containing the vocal cords), the trachea (wind pipe), the
bronchial tubes, and the lungs. It has a dual purpose in the dog: to remove
carbon dioxide from the body replacing it with oxygen, and to act as a cooling
system. Since dogs do not have sweat glands they cannot perspire to lower their
body temperature. By breathing faster, warm air from the body is exchanged with
cooler air from outside.
The act of breathing is accomplished by the actions of the rib muscle and the
movement of a large internal muscle called the diaphragm. The diaphragm
separates the chest from the abdomen. Movement toward the abdomen causes the
pet to breathe in fresh air. As the pet inhales, fresh air moves through the
nose and larynx to the trachea. This rigid tube is supported by tough rings of
cartilage. It carries the air to the bronchi, which in turn supply the lungs.
What is a collapsed trachea?
The trachea is supported by tough rings made of cartilage. Occasionally, the
trachea will lose its rigidity and collapse while the dog is breathing. For
unknown reasons, the cartilage rings weaken and the trachea no longer has
proper support. The collapsing trachea syndrome is most often seen in toy
breeds, especially Toy Poodles over the age of five.
What are the symptoms?
The symptoms of this syndrome depend on the severity of the deterioration.
Usually, the dog will have difficulty breathing, especially during exercise.
The deeper the pet tries to inhale, the more the trachea collapses, further
restricting air flow (similar to sucking on a straw too hard). The pet appears
to tire easily as it becomes short of breath. Dogs with a collapsing trachea
will generally cough as if trying to clear the airways, and occasionally this
cough will sound like a goose honk. In very severe cases, the tongue and gums
will appear blue as breathing becomes restricted.
What are the risks?
Most dogs suffering with the collapsed trachea syndrome live normal - but
restricted - lives. Activity is generally limited because the ability to
breathe deeply when exercising is hindered. Left untreated, the restricted air
flow can put undue stress on the heart and lungs as they try to compensate for
the inability to breathe properly. Obese dogs are at greater risk than others.
What is the management?
Examination with the fingers and radiographs (x-rays) will generally confirm
the diagnosis. Depending upon the severity of the condition, medications will
help. Veterinarians usually prescribe drugs to help dilate the airways. The
coughing is controlled by cough suppressants such as Torbutrol. If the pet is
obese, we suggest a stricter diet. Finally, activity should be restricted and
not encouraged. Dogs with collapsing tracheas should wear harnesses instead of
collars in order to take any pressure off of the trachea. With the help of
medication and modification of lifestyle, the collapsing trachea can be
controlled but seldom cured. In severe cases, surgery to help open the airways
may be beneficial, but most cases are managed medically not surgically.
