DOG DISEASES 243 



ers confuse the terms inbreeding and line breed- 

 ing. In fact, there are really only three types of 

 inbreeding, that is, crossing the blood of a single 

 individual. They are inbreeding a sire to his own 

 daughter, a dam to her own son or full brother 

 and sister together. Where similar blood lines are 

 used in combination different from the above, 

 they might be termed, as a rule, line breeding. 

 An outcross is obtained when a deviation is made 

 to a dog or bitch possessing blood lines entirely 

 dissimilar from those appearing previous thereto.

POOR DIET — POOR CONDITIOIT 



I have an Airedale about ten months old that 

 is having trouble with small warts coming out all 

 over the roof of his mouth and on his lips. 



The dog does not seem to be as lively as he did 

 a month ago and wants to be in the house most of 

 the time (although he sleeps out nights), lying 

 down instead of running around out of doors as 

 previously. He does not eat much and spends a 

 great deal of his time scratching his neck and bit- 

 ing himself all over, although he does not seem to 

 scratch his ears ; it all seems to be on his neck or 

 body ; also rubs his head along on the ground some 

 when outdoors, rubs his front paws over his eyes
