Puppies used in the study: Size, breed, number of litters and gender (female and male).
Table 2.
Behavioral response and scoring protocol for the 5 subtests.
All puppies were individually recorded under each test in a novel space. Video recordings of their behavioral responses in each subtest were independently scored by three assessors using a scale of 60/75/100 to 300.
