cidentally to hinder, by the soreness of the tongue, the 

 disposition of mischievous puppies to destroy carpets, 

 slippers, etc., within reach. 



Ingrou-n Nails. — Working dogs, and those enjoying 

 abundant exercise, wear down the nails to a convenient 

 length, but pet animals living very much in carpeted 

 rooms, suffer from overgrowths necessitating periodic 

 shortenings with scissors made for the purpose. Those 

 nails upon the so-called dew claws grow in a circle, and 

 if not shortened, as above advised, eventually pierce the 

 pad. The vascular and sensitive portion of the nail grows 

 in correspondence with the insensitive, and cutting back is 

 a somewhat painful operation if long neglected. 



Canker of the Ears. — Several forms of irritation in the 

 meatus, and generally termed ' canker ' by dog owners, 

 are largely preventable by simple measures, such as the 

 introduction of a little camphorated oil at night, followed 

 by a careful syringing next day to remove the dust and 

 debris which is specially noticeable in dogs allowed to follow 

 carriages. The presence of a symbiote {Symbiotes auris 

 canis) in the meatus is a frequent cause of itching, and the 

 condition known as canker results from the animal's own 

 efforts to dislodge him by striking the base of the ear with 

 the hind foot. Serous abscess occurring between the inner 

 reflection of skin and the cartilage of the flap of the ear is 

 often the result of shaking the head violently when annoyed 

 by the parasite above mentioned. 



Mange. — Immediate isolation of infected subjects is 

 important, as the acari are readily transferred, and in the 

 case of long-haired dogs not easily eradicated without 

 clipping and consequent disfigurement for a long period. 

 A 4 per cent, creolin lotion is a safe and effectual remedy, 

 and should be repeated at the time when a second brood 

 may be expected. 



Distemper. — It is to be regretted that up to the present 

 time no real prophylactic has been discovered, nor does it 

 seem at all clearly proved to be due to one specific organism.
