64 DISEASES OF DOGS. 



who holds him, and then pourmg a Kttle into the ear-passage, 

 holding the dog in the same position for a niinute or two, until the 

 liquid finds its way into the seat of the disease. The preparation 

 should also be applied freely to aU the external sores. If there he no 

 dark and offensive discharge from the ear, the carbolic acid and 

 glycerine may be omitted from the lead Uniment ; and I may here 

 observe that I mean that article to be of the strength ordered in the 

 British Pharmacopoeia, viz., 1 part pure carbolic acid in 5 parts pure 

 glycerine. 



Another treatment for internal canker is to syringe the ear once 

 a day, or night and morning, according to the severity of the case, 

 with 1 part of spirit of wine and 20 parts of lukewarm water. 

 AUow the dog to shake his head afterwards to remove the superfluous 

 fluid, then dry the ear thoroughly with cotton-wool, roUed upon the 

 end of a probe or pointed stick. Several pieces of wool will be 

 necessary. When the ear is perfectly diy, introduce into the cavity 

 finely powdered boraoic acid, seeing that it reaches the bottom. In 

 some cases that do not yield to this treatment, powdered iodoform 

 can be used in place of the boracic acid. If any of the sores outside 

 look "angry," scrape with a knife a little bluestone into fine 

 powder and dust them with it ; or, after bathing and di-ying nicely, 

 touch them with a point of lunar caustic. It will be of advantage, 

 in treating canker of the ear, to give the dog a purgative, and iu 

 many severe and stubborn cases the administration of the Fever 

 Mixture for a few days after the purgative wiU be of great benefit. 

 The diet must be light, and consist partly of boiled green vege- 

 tables. 



Many of the best writers on dog diseases recommend a cap to be 

 worn by the dog in external canker of the ear to prevent the flapping 



and consequent irritation and in- 

 jury to the tips of the ear from the 

 violent shaking of the head, but 

 so far as my experience goes, I am 

 of opinion that it does more harm 

 than good. But those who wish 

 to try a cap (Fig. 11) can readily 

 make one with a piece of canvas of 

 suflicient length to reach round the 

 dog's head, having two pieces of 

 tape running through a hem at 

 each side lengthwise, wherewith to

neck behind the ears, and again, 

 just above the eyes, tying them underneath.
