assume their normal size and condition. A temporary con- 

 gestion may also occur from collars being too tight, or dogs 

 pulling on the leash, which disturbs the circulation in the 

 glands. Swelling of one or both glands may result from this 

 and last for several days simulating goiter. As soon as the 

 cause is removed the circulation will return to its normal 

 state and the congestion gradually disappear. Direct 

 injuries to the glands are not uncommon and congestion and 

 edema result. Examination will often reveal the presence 

 of a wound or a contused area. Permanent enlargement of 

 one or both glands may result from injuries, due to fibrous 

 formation. 



ACUTE THYROIDITIS. 



Definition. An acute inflammation of one or both thyroid 

 glands. This condition has been observed in dogs. 



Etiology. The majority of cases are secondary to other 

 diseases, such as distemper, local infection in the adjacent 

 tissue, or from direct injuries. 



Symptoms. The glands are first noticed to be prominent, 

 enlarged, sensitive on palpation, and the local temperature 

 elevated. In severe congestion the gland will often show 

 pulsation. A differentiation should be made between this 

 condition and the various forms of goiter. The sudden 

 development, local heat, and marked reaction in the glands 

 will assist in making the differentiation. The history of 

 the condition following distemper or injuries should also be 

 taken into consideration in making the diagnosis. 



Prognosis. The termination of acute thyroiditis is usually 

 favorable. The inflammation subsides and the gland resumes 

 its normal function. Some few cases terminate in a degenera- 

 tion and suppurative condition which may destroy a part 

 or the whole gland. It is possible also to have the condition 

 become chronic and produce a firm fibrous growth simulating 

 some forms of goiter. 



Treatment. During the acute stage cold applications 

 should be applied either in the form of cold water or ice packs. 

 This followed by a hot Priessnitz compress and continued 

 until resolution takes place or degeneration and abscess
