what causes water on the brain
Intracranial (within the brain) pressure is a normal result. This is ventricular dilation incidental to the primary disease. Overproduction of spinal fluid can also cause hydrocephalus. However, this is rare. A tumor in the eye may also cause water on the brain. The congenital form of hydrocephalus is more likely to occur in small and brachycephalic dogs: bulldogs, Chihuahuas, Maltese, Pomeranians, Toy Poodles, Yorkshire Terriers, Lhasa Apsos, Cairn Terriers, Boston Terriers, Pugs, and Pekingese.
