Dogs are supposed to be assessed on day two.

From page 44 on the DTA IV Training Course by Rebecca Ledger (one of the SPCA "scientists" who cobbled together CAMP, the SPCA's dog tests.)

"Validation procedure at the BC SPCA
211 dogs were assessed using DTA IV on day 2 of their stay in kennels. 106 dogs were eventually adopted by new owners. These owners were contacted one week and one month later, when they completed questionnaires regarding how the new dog behaved in its new home."
