28o THE MANAGEMENT AND DISEASES OF THE DOG. 



masses, as black as ink, varying in size from a millet-seed to a 

 large pea. He had opened the dog, and stated that he found 

 the swelling on the leg full of black matter. The liver, heart, 

 other portions of the lungs, and beneath the skin over the 

 body, were all in the same condition as the portion of, lung 

 ■which he brought to me. Examination of the latter proved 

 that the deposits were of a melanotic nature, and no doubt 

 had been the cause of death." 



BRONCHOCELE, 



Or enlargement of the thyroid glands on one or both sides, 

 is commonly met with in every breed of dogs, The cause of 

 this glandular enlargement is somewhat doubtful. Animals 

 in a debilitated condition appear most liable to it, while, on 

 the other hand, those in robust health will become affected. 



The anatomical formation of the neck and throat would 

 seem to have some predisposing inflifence ; for short, thick- 

 necked, throaty dogs are those, according to my experience, 

 most frequently the subject of this disease. 



Symptoms. — Bronchocele may come on insidiously or sud- 

 denly ; hence we hear of dogs, to use a common expression, 

 with " kernels " in the throat, which have been observed there 

 for some time, but become no larger. Others are discovered 

 to have an immense swelling at the throat, which was un- 

 detectable the previous day. . 



In cases where the thyroid enlargement is considerable, 

 difiSculty in breathing will be one of the prominent symptoms ; 

 this arises from pressure by these enlarged glands on the 

 trachea, which also cause much inconvenience to the neigh- 

 boring structures, as the throat and -vessels of the neck, 

 creating obstructed circulation and difficulty in swallowing. 



Treatment. — Our object in the treatment of bronchocele is 

 to arrest growth and promote absorption. Iodine, externally 

 and internally, is the most powerful remedy for this purpose.
