Ulcerous Affections, 



Dogs are subject to ulceration of various parts of the body, 

 dependent on very different causes. Cancer, which is the 

 worst ulcer we are acquainted with, is but little common in 

 the dog-. Those cases, however, in canine pathology, that do 

 approach its character, are noticed under the head Cancer. 

 A very malignant ulcer sometimes breaks out in the lips, 

 face, or neck, in distemper, and is there noticed. In virulent 

 canker, the internal, and sometimes the external ear also, 

 become attacked with extensive ulceration. I have seen it 

 proceed so far, in these cases, as to destroy the dog. The 

 eyes become very commonly ulcerated in distemper ; and 

 as commonly, when the distemper is cured, they reinstate 

 themselves, although the ulcerative process was very consi- 

 derable. 



Glandular parts in dogs are very liable to ulceration ; the 

 most common among which are the teats in bitches. — See 

 SciRRHUs. — The vagina, sheath, or bearing, and sometimes 

 the womb also, are found to be aflected with a morbid ulcer- 

 ous state, which is very usually accompanied with a fungous 

 excrescence, from which blood exudes, or a bloody ichor. 

 This disease participates more of the nature of cancer than 

 any other to which dogs are generally liable. — See Cancer. 



The penis is likewise the subject of an ulcerous affection, 

 which is also commonly accompanied with a spongy fungous 

 excrescence, exuding a bloody ichor : but it does not erode 

 the neighbouring parts, and appears to partake more of the 

 nature of a vascular warty substance, than that of cancer. 



This fungous excrescence on the penis is often mistaken for 

 a disease of the kidneys or bladder. A few drops of bloody 

 fluid appear now and then to come from the dog; and, as in
