Sometimes, owing to brain complication, the sufferer 
engages in a continual walking in one direction, and in 
the form of a circle, evidently in a state of stupor or 
partial insensibility, which terminates in complete coma 
and death. 
The Respiratory or Pulmonary form of Distemper is 
essentially that of Bronchitis of a low and aggravated 
character, the post-mortem evidences being those 
common to the usual disease of that name, but asso- 
ciated with general specific blood derangement. (See 
Bronchitis.) 
In the Biliary or Hepatic form jaundice is conspicuous 
by the yellow colour pervading the tissues generally. 
The tinge, more or less intense, is seen to great advan- 
tage in the mucous membranes of the mouth, tongue, 
nostrils, eyelids, eyeball, the haw, vulva, and rectum. It 
is associated with intense depression, a feature which 
adds considerable difficulty in combating the associated 
blood poison and its destructive effects. (See Jaundice.) 
Enteric or Intestinal Distemper is principally confined 
to younger dogs and puppies, which are peculiarly liable 
in their immature state of physical development to con- 
tract a state of blood disease, even under the least 
favourable circumstances. Worms in the intestines, also 
teething, often prove exceedingly trying to these creatures, 
and under their continued effects, without due care as to 
suitable food, exercise according to capacity, comfortable 
quarters, &c., the causes of blood derangement are not 
far distant. 
In ordinary Distemper the tendency to a loose state of 
the bowels is general, thus completing the list of signs 
which are characteristic of blood diseases. <A state of 
looseness is often present from the first, the feeces being 
laden with mucus shed by the lining membrane of the 
bowels. Further action induces congestion of the tissues, 
which is followed’ by rupture of the minute vessels ; 
blood oozes, and being irritant as well as an animal 
poison, causes stoppage and sloughing, when an ulcer 
forms, another source of bleeding; thus the feces
