124 KENNEL DISEASES. 
with sweet oil, a tablespoonful of each may be given to dogs of large size. 
Double that quantity of the buckthorn might be given if used alone, and brisk 
and free action is desired. 
In attacks of sickness in which there is fever it is generally advisable to un- 
load the bowels, and then calcined magnesia acts well, either alone or combined 
with powdered rhubarb. The dose of the former is a full teaspoonful for large 
dogs ; and if a good purging is deemed necessary, with it should be mixed nearly 
half a teaspoonful of the latter. 
Among the purgatives in pill form the so-called compound cathartic pill is as 
good as any if the bowels are not irritated; and three for dogs of the largest 
size, two for the medium, and one for fox-terriers and the like, are suitable doses. 
As for the smallest toys, magnesia is the best for them. 
In occasional cases the retained refuse is so dry and hard, that cathartics are 
very slow in having their effect ; and in such, also in every instance in which it is 
desirable to have the bowels move at once, an injection should be given. For the 
purpose a simple and efficient mixture may be made of strong soapsuds and 
water, to which has been added a teaspoonful of molasses and the same quan- 
tity of table-salt. As an injection, sweet-oil also acts speedily and well when 
generous quantities are used. A cupful would be none too much for the largest 
breeds. Another efficient remedy is glycerin, of which only a little need be 
injected to move the bowels, — from a teaspoonful to a tablespoonful, according 
to the size of the patient.
