Dog on a Caboose

The conductor takes his dog along as a companion on N scale logging run. The caboose is a Kadee 50040 (pre “Micro Trains Lines”) Originally lettered for Santa Fe, which I model, but Santa Fe had no cabooses like these. However, it is a model of a Southern Pacific prototype, and an identical (except 160 times bigger) SP caboose was sold second-hand to Texas & Southeastern logging railroad.
