LOCAL AFFECTIONS OF THE NASAL PASSAGES. 2:'>3 



When a catarrh does not yield to treatment in a mod- 

 erate period, the dog should be anaesthetized and a care- 

 ful examination of the nasal passages and month made l)y 

 the help of bright sunlight or a reflecting mirror and a 

 speculuna. 



If growths are found, they should be at once treated 

 either by burning off with a strong wire at a bright-red 

 heat, or torn out, if larger, with a wire snare, and the bone 

 cauterized with the hot wire as before, which usually also 

 arrests all haemorrhage. 



These chronic catarrhs tend to undermine the health 

 of the animal and to become less amenable to treatment 

 the longer neglected. 



The nose must be washed out with a syringe and warm 

 water, to which a little carbolic acid (about five grains to 

 the pint) has been added ; or, better still, if the dog can be 

 kept quiet, a spraying apparatus may be used, though, con- 

 sidering the length of the dog's muzzle, this is somewhat 

 difficult to manage. 



For a spray such a formula as the following will prove 

 very useful : 



9- Sodae biborat 3 j ; 



Sodae carb 3 j ; 



Acid, carbolic , gr. v ; 



Glycerinae 5 j ; 



Aquae ad § viij. 



M. Inject. 



Often the cleansing in this manner, faithfully carried 

 out, will effect a cure. If not weak, astringent solutions 

 may be sprayed up the nostrils or carefully injected by 

 a syringe ; but strong applications do only harm.
