Congenital cerebrospinal hypomyelinogenesis in a pup.
One of 8 highly inbred Dalmatian pups was born with generalized body tremors, which interfered with the pup's ability to suckle, walk, and maintain sternal recumbency. The pup's head, neck, and limbs oscillated rhythmically when it attempted to perform any motor function. The pup was euthanatized at 8 weeks of age, after it became apparent that the disorder was likely to be permanent. The histologic diagnosis was cerebrospinal hypomyelinogenesis.
