Surgical Diseases and Surgery of the Dog 



No. 3. Simple raazzle of tape or 

 tope. 



AFFABATTJS AND METHODS OF RESTRAINT. 



Muzzles. Mouth Speculums. The simplest method to pre- 

 vent the dog from biting is to select a piece of tape or soft rope, 

 make an overhand knot or a half hitch in the same, slip the loop 



over the closed jaws with the knot or 

 hitch undermost, tighten the latter, 

 carry the free ends under the ears to 

 the back of the head and tie there in a 

 bow-knot. Fractious animals should be 

 held by their owners and prevented from 

 backing away or turning the head 

 while this is being done. All short- 

 faced animals (Bulldogs, Boston Ter- 

 riers, Pugs, Toy Spaniels), in which the 

 capacity of the nasal passages is small 

 must be secured in this manner with ex- 

 treme caution. Under even a moderate 

 degree of excitement their nasal pas- 

 ages are insufficient to accommodate 

 the increased respiration, and these animals are forced to breathe 

 by the mouth. If this avenue is closed suffocation results, and the 

 heart may be overstrained or rupture of the pulmonary vessels take 

 place, to be followed by death within a few hours. The jaws may 

 also be secured with the ordinary muzzles sold in the stores, but 

 very few of the latter are really effective for this purpose. 



In some cases, particu- 

 larly of fractious animals, mor- 

 phine is very useful as a means 

 of control, injected hypoder- 

 mically. It renders an animal 

 contented, more or less obliv- 

 ious to its surroundings and 

 unmindful of slightly painful 

 manipulations. 



Hopples. There are sev- 

 eral patterns sold by the in- 

 strument makers, but of these 

 I can confidently recommend 

 as the best the portable Daw- m„ ^ ,, r, ,.„....„.
