continuing from condition / disorder #240 -
Quote:
241. Perianal fistulas: a condition characterized by abnormal communications from
deeper tissues to the skin surrounding the anus.
242. Perianal gland tumor: (See #240.)
242a. Peripheral sensory neuropathy: a disorder of young puppies born without pain
sensation of peripheral tissues. (also see #8.)
243. Persistent right aortic arch: a developmental abnormality where one of the fetal
blood vessels near the heart does not atrophy as it should.
244. Persistent hyaloid artery: as #243, however, involving a blood vessel inside the
eye.

enzyme in the English Springer Spaniel. Causes chronic anemia, exercise-induced
acute hemolytic crises and enlarged spleen.
245b. Physiologic leukopenia: a condition of most healthy adult Belgian Terverun
whereby the total white blood cell count (neutrophils, lymphocytes, and monocytes) is
below 6,000/ul. Because of their ancestral relationship to the other Belgian Shepherd
dogs (Belgian Sheepdog and Belgian Malinois), these breed/varieties may also show
the same phenomenon.

causing varying degrees of liver dysfunction or failure. This condition can also be
manifested as microvascular dysplasia. *Yorkshire and Cairn Terrier, but can occur in
any breed. (also see #149, 199a.)
253. Posterior retinal atrophy: a deterioration of the part of the eye which translates

animal has the gonads of one sex, but the appearance is ambiguous or is of the
opposite sex.
