Kousso and pomegranate bark are not now often used.

Pink and senna. An extract of pink and senna com-

 safe. However, it acts very dissimilarly on different dogs, 

 and should be used tentatively i. e., the dose should at

It is one of the best remedies for puppies still sucking.

 till three or four doses have been taken at intervals of an 

 hour, then followed by castor oil ; or santonine may be com-
