140 Blood Diseasés. 
Obesity.—Following hard upon the conditions of 
Plethora is the disposition to accumulate fat. The 
degrees of this are various, culminating in a state of 
superlative inability, associated with positive ugliness. 
Internally the organs are surrounded by accumulations 
of fat, which irapede the essential functions, and often 
cause sudden death. Even the muscles are replaced by 
fat, and the animal is a trouble if not a torture to 
himself. 
The Causes are those enumerated under Plethora, a 
discontinuance of which must be ensured before curative 
measures can be successful. 
Treatment.— Avoid the causes which generate Plethora, 
Institute gentle exercise, gradually increased as the effects 
are fruitful. Substitute a less fattening diet. In spite of 
these measures some cases refuse to yield even to the

In such an event regular doses of iodine should be 
given in conjunction with aperient medicines at stated 
intervals. 
Anemia,— Deficiency of Blood.—This definition indi-

The deficiency applies to the padu/um or rich elements 
needful for building up the body. It is the disease of 
badly fed dogs, especially puppies, in which the organis-

of overcrowding, bad smells, want of light and fresh air, 
especially when unsuitable, or unnutritious and in- 
digestible food is supplied. 
Symptoms.—W eakness, often amounting to prostration, 
precarious appetite, indisposition to rise, generally 
depressed spirits, cold limbs, which sometimes swell, 
pallid membranes, staring coat, scanty excretions, with 
general inability for any exertion. The mouth is cool 
and the gums with the tongue are remarkably pale. 
Diarrhcea usually supervenes and terminates fatally. 
Treaiment.—Remove the cause. Supply good food 
judiciously, together with fresh air, water, etc. Treat the 
diarrhoea by means of half or quarter doses of oil and 
laudanum, and when successfully arrested, commence
