It is due to the presence of a vegetable fungus in- 

 vading the hair follicles and shafts of the hairs, 

 causing the latter to break off, which gives the area 

 of disease a stubbly appearance. This trouble is 

 characterized by the formation of circular patches 

 upon the skin, which are of a dry, scurfy appearance, 

 of a slaty colour, spreading from the centre to the 

 circumference. As ringworm is common in calves 

 it is quite possible that the dog may contract it 

 from this source of infection, but it is not an un- 

 common disease amongst cats, so that a cat may 

 really transmit the disease to a dog, or it may be to 

 man. There is a tendency for ringworm to exhaust 

 itself, so that spontaneous recovery is by no means 

 unknown. The best treatment is to paint the part 

 with iodine liniment, or with a solution of hypo- 

 sulphite of soda. If an ointment is preferred 

 chrysarobin ointment is the best remedy, but there 

 are many other applications suitable for ringworm, 

 and whatever is applicable in the case of man and 

 other animals is, as a rule, equally suitable for the 

 dog.

This skin trouble is mostly seen in young dogs, 



say under twelve months, but occasionally in older 



ones. It is due to a vegetable parasite, and of an 



infective nature, so that one hound may convey it
