Table 2.

Comparison of sleeping location in Dogslife record with visit response. Numbers entered refer to the count of households.

Dogslife	Visit response
	Alone, n	Shared (family), n	Other (shared with dog)a, n	Other, n
Alone	24	1	2	0
Shared (family)	0	7	0	0
Other (shared with dog)a	0	0	8	0
Other	0	0	1	0

^aOther (shared with dog) was not an option in the original questionnaire. During the validation, it became apparent that dogs that slept with other dogs were categorized inconsistently as (1) Alone, (2) Shared (family), and (3) Other: (with other dog). Introducing sharing with another pet as an explicit option prevents this inconsistency.
