dogfs ; the worms, when occurring in large numbers, 

 cause derangement of digestion, dullness and indif- 

 ference ; the young pup may whine or cry ; tympani- 

 tes, and in some cases diarrhoea ; there is loss of 

 appetite, nervousness and in some cases nausea ; 

 later anemia and emaciation is noted and the animal 

 succumbs to the disease. 



Treatment. — Santonin and areca nut prove the 

 most effectual parasiticides. The areca nut is an 

 irritant to the bowels and acts as a vermifuge or 

 purge. The following combination gives good 

 results in ridding the bowel of these worms.
