In dogs, several types of tumors resemble human tumors in many respects. Therefore, several groups have developed the anti-dog programmed cell death ligand 1 (dPD-L1) monoclonal antibodies (mAbs) and showed efficacy in several canine tumors. To examine the abundance of dPD-L1 in canine tumors, anti-dPD-L1 diagnostic mAbs for immunohistochemistry are required. In this study, we immunized the peptide in the dPD-L1 intracellular domain, and established anti-dPD-L1 mAbs, L<sub>1</sub>Mab-352 (mouse IgG<sub>1</sub>, kappa), and L<sub>1</sub>Mab-354 (mouse IgG<sub>1</sub>, kappa). In enzyme-linked immunosorbent assay, L<sub>1</sub>Mab-352 and L<sub>1</sub>Mab-354 showed high-binding affinity to the dPD-L1 peptide, and the dissociation constants (<i>K</i><sub>D</sub>) were determined as 6.9 × 10<sup>-10</sup> M and 7.2 × 10<sup>-10</sup> M, respectively.
