312 THE MANAGEMENT AND DISEASES OF THE DOG. 



vidual who is confined in a crowded ill-ventilated workshop 

 throughout the day, as contrasted with one whose occupation 

 gives him every chance of imbibing pure, or, at any rate, fresh 

 air, and you have a true and daily illustration of the effect of 

 these sanitary arrangements, which may be with equal force 

 applied to the canine race. 



Indeed, fresh air and light are as essential to dogs, for the 

 formation of good blood, as to man. Air must, to maintain 

 health, be renewed, not re-used. It is the oxygen which gives 

 color to the blood. Stint the supply of this necessary ele- 

 ment, and though externally not so perceptible in dogs, you 

 withdraw the coloring matter, and obtain the same pallid 

 condition. Again, good nutritious food is just as necessary 

 for the production of pure blood and healthy muscle. We 

 may as well try to build a strong substantial house out of bad 

 materials, as expect that blood derived from such a source, 

 and under the circumstances enumerated, will make sound 

 strong muscle. 



Symptoms. — Anasmic animals generally exhibit consider-

 inside the Ijps, the tongue is also unusually white and dry, the 

 extremities are cold, and the limbs not unfrequently swollen, 

 and the secretions and excretions scanty. 



M. D' Arbor relates the following cases : 



" Two dogs were sent into the hospital of the Veterinary 

 School at Lyons. They did not appear to suffer any consid- 

 erable pain. Their skin and the mucous membranes that 

 were visible had a peculiar appearance. They had also com- 

 paratively little power over their limbs : so little, indeed, that 

 they rested continually on one side, without the ability to 

 change their posture. When they were placed on their feet 

 their limbs gave way, and they fell the moment they were 

 quitted. Notwithstanding the care that was taken of them, 

 they died on the second day. 



" Incisions were made through the skin, but in opening
