132 CANINE DISTEMPER 
rences are not infrequent under conditions which favour 
them. Failure to detect and treat distension of the 
bladder will lead to a loss of its contractile power, and 
symptoms of incontinence may then be manifested, which 
for this and other reasons may endure for months, and, 
in the case of an old dog, perhaps for the remainder of 
its lifetime. 
Hydrocephalus.—This sequel is rarely seen, though it is 
known to have followed distemper. Frohner reported 
having diagnosed it in only twenty-nine cases out of 
seventy thousand dogs which passed through his hands 
in Berlin. The dog becomes a complete idiot, pro- 
gressing with a staggering gait, holding the head to one 
side, staring stupidly at objects it encounters, hiding in 
dark corners, listless and defective in sight and scent, 
and presenting a pathetic picture of its former self. 
Sometimes large amounts of fluid are found in the lateral 
ventricles of the brain on post-mortem examination. 
It will be realised from a consideration of these mani- 
fold symptoms how completely the whole body may 
sometimes be implicated in this dread disease, and 
yet at others how extraordinarily benign the attack 
may be.
