Tracheal Collapse

                       -----------------

                      General Information



The trachea (windpipe) is composed of 35-45 C-shaped rings of

cartilage that are joined by muscle and ligaments to create a

tube-like structure.



Certain conditions can result in the trachea's losing its

tube-like shape so that it collapses, much like a soda straw

being drawn on too vigorously.  When the trachea collapses, air

can no longer move freely through it.  Then the animals breathes

with difficulty and exhibits a honking cough.



Causes include trauma to the windpipe, nerve damage, inherited

tracheal weakness, degeneration of cartilage and abnormal air

flow in and out of the lungs.



Except for the congenital (present at birth) forms of tracheal

collapse, most cases occur in middle-aged or older, overweight,

small-breed dogs.



                 Important Points in Treatment



1.  A complete physical examination and radiographs (x-rays) are

    usually necessary to confirm a diagnosis of tracheal

    collapse.



2.  Depending on the severity of the condition, treatment may

    include surgery and/or medical therapy.  In mild cases, a

    change in the pet's lifestyle may be all that is necessary.



3.  Some cases of collapsing trachea cannot be cured, and

    treatment is directed at decreasing the severity and

    frequency of breathing difficulties.



4.  Special instructions:





        Notify the Doctor if Any of the Following Occur:



    * You cannot carry out the prescribed treatment.



    * Your pet's condition worsens.



    * Your pet coughs up blood.
