282 '-THE DOG IN DISEASE. 



occurs it is to be recognized by wasting, altered respira- 

 tion, cough, etc. — in fact, the same symptoms as in other 

 animals, while the treatment must be on similar lines also. 

 For dogs to swallow the sputa of consumptives is dangerous. 



LOCAL AFFECTIONS OF THE NASAL PASSAGES. 



Nasal Catarrh. — Sometimes, though rarely, as the result 

 of a " cold," more frequently of a succession of '^ colds," 

 in dogs badly kenneled, an excessive discharge of muco- 

 purulent matter from the nose results, and is an indication 

 of a relaxed and weakened if not a low inflammatory con- 

 dition of the membrane lining the nose. It is apt to fol- 

 low distemper, and to improve or get worse as the dog's 

 general health varies. 



Yery often the mucous membrane covering the front 

 of the eyeball and the inner surfaces of the lids {conjunc- 

 tiva) partakes sympathetically (reflexly), or as a result of 

 the original inflammation of distemper, etc., in the ca- 

 tarrhal condition. 



If unchecked, the nasal catarrh may lead to ulceration 

 of the soft parts of the nose or to inflammation of the 

 bones of the organ, with resulting death of part of the 

 bone (necrosis, caries) ; or the secretion may become al- 

 tered, or be retained and give rise to a most offensive 

 smell. From such inflammation, catarrh, etc., nasal polypi 

 or growths of a highly vascular character occasionally arise, 

 and may so obstruct respiration, or cause such disturbance 

 generally, as to demand treatment. 



Acute catarrh when not associated with distemper does 

 not usually require local treatment in the dog, as it is 

 transient.
