Owned dog demography in Todos Santos Cuchumatán, Guatemala.

A thorough knowledge of the dog demography should be an integral element in the planning, implementation and evaluation of dog population control measures. In May 2008, a door-to-door household census of human and owned canine populations was conducted in 12 contiguous neighbourhoods in the town of Todos Santos Cuchumatán, Guatemala. During the census, household and footpath data were recorded using a handheld Global Positioning System (GPS), and used to create digital census route maps, and perimeter and area estimates of the study region. Approximately 99% of all households (472/476) participated in the census, representing 2461 people in the overall estimated study region area of 80 hectares (ha). A total of 382 dogs were owned by 50.8% (240/472) of households, yielding means of 0.8 (382/472) owned dogs per household and 1.6 (382/240) dogs per dog-owning household. Of the total 382 owned dogs, 88.2% (337/382) were aged three months or older; of these, 68.5% (231/337) were reported as not normally being confined on the household property during the average day, and 9.7% (24/247) of the males and none of the females (0/81) were reported to be neutered. Of the households that owned female dogs, 89.7% (52/58) and 91.4% (53/58) reported that they would have females surgically or non-surgically neutered, respectively, if these services were available. Of the households that owned male dogs, 90.3% (176/195) and 92.3% (180/195) reported that they would have males surgically or non-surgically neutered, respectively, if these services were available. Approximately 72% (238/330) of owned dogs were vaccinated for rabies, and 80% (187/238) of these were males. The owned dog male:female ratio was 2.6:1 (275/107), the owned dog:human ratio was 1:6.4 (382/2461), and the absolute density was 478 (382/0.80) owned dogs/km(2). This knowledge of the owned dog demography was generated using simple means and has been of direct use in support of, and as baseline data for the planning, implementation and evaluation of subsequent dog population control measures in this population; they may be of similar use in other comparable populations.
