30 THE DOGS OF THE BRITISH ISLANDS. 



The REMEDY for this state is a cooling diet, without any animal food of any 

 kind, and composed chiefly of potatoes and other vegetables. A smart purge may 

 be first given, and then the liquor arsenicalis in doses of from two to ten drops three 

 times a day, mixed with the food, according to the size of the dog. If this dose 

 makes the eyes red, or stops the appetite, or occasions vomiting, it may be diminished 

 one-half; but the best plan in all cases is to begin with a full dose at first, and when 

 the desired effect is produced, gradually to diminish it. Less than two or three 

 months will seldom effect a cure, and green iodide ointment will often be required 

 to complete it. 



3. RED MANGE, is the most easily detected of all the varieties, because it 

 always shows itself by altering the colour of the hair, whether the dog is white or 

 not. If white, the hair becomes pink ; and if brown or red, it is of a brighter 

 shade ; while if black, it becomes reddish brown. It does not, however, fall off, 

 except from the constant scratching which takes place. There is no eruption visible, 

 but the skin is more red than natural. 



The REMEDY is either the ointment of green iodide of mercury, which, however, 

 sometimes fails, or Bishop's mange lotion wash above mentioned applied to the roots 

 of the hair with a stiff brush every other night. Liquor arsenicalis should also be 

 given as above described. 



BLOTCH OR SURFEIT is one of those skin diseases which is dependent upon 

 too gross a diet, and is not of a specific nature, that is to say, it is not caused by 

 contagion, nor by a parasitic insect. It begins with an irritation of the skin, which 

 causes the dog to be constantly scratching. On examination, there is a matted 

 mass of loose hair, as if some starch had been dropped on the coat ; and when 

 this comes off, the skin underneath is red, and deprived of its cuticle, dis- 

 charging also a thin watery fluid. These patches occur chiefly on the back and 

 the inside of the thighs, and also on the scrotum, where they are very commonly 

 met with. 



The TREATMENT consists in giving cooling and laxative medicines, with 

 starvation and plenty of exercise. This will almost always effect a cure. Locally 

 a piece of bluestone may be rubbed upon the sores, but they will not heal until the 

 constitutional foulness of blood has been relieved, after effecting which local 

 measures are seldom needed. 



An ERUPTION between the toes is also constantly occuring in sporting dogs ; 

 and it is precisely similar in its nature and cause, and also in the treatment. 

 Bluestone is almost invariably successful, if combined with purgation and starvation. 

 It generally requires to be well rubbed into the roots of the nails, and also to the 

 clefts between the toes. 



INFLAMMATION OF THE ORGANS OF RESPIRATION. 



The LARYNX, situated at the top of the windpipe, is not so often the seat of 

 acute inflammation as in man and the horse, but chronic laryngitis is by no means 

 unfrequent in the dog. Both are recognised by the hoarseness of the cough and
