Nevertheless with a series of liver treat bribes we have
been able to distract his vocal prowess sufficiently to
chart the improvement in the "squeaks and crackles"
heard throughout his lung fields.
The respiratory tract within the chest ends in very thin
and delicate tissue in order to facilitate the transfer
of oxygen into the bloodstream. In the case of "allergic
bronchitis" the respiratory lining becomes thickened
as a result of a large influx of inflammatory cells. This
interferes with the efficient transfer of oxygen into the
bloodstream and eventually triggers the cough reflex as
the amount of cellular debris or mucous accumulates within
the respiratory tract.
Treatment is aimed at "thinning" the inflammatory
component to improve the overall function of the lungs to
transfer oxygen. Whilst no-one fully understands why this
process occurs it seems likely that with the high incidence
of disease in small terriers there is probably a genetic
predisposition compounded by an allergic reaction. This
is also thought to be the case in humans for many asthma
