with scissors. After the opposite ear has been similarly treated, the 

 operation is complete. During healing, however, the resultant scar 

 tissue forming at the wounded edge is very apt to cause the forma-

 ears in after life. This must be guarded against by submitting the 

 ears to a "pulling" process, or in other words, tearing apart any too 

 freely contracting cicatrization. For this reason, no animal which has 

 undergone the operation should be dismissed by the practitioner until 

 complete regular healing has been established. It is generally a few 

 weeks, or until all soreness has departed, before the ears are held 

 fully erect.
