Terca

Terca

Terca is the smallest of the dogs, but has the biggest bark. The first thing you hear when you enter Black Rock Automotive, is Terca announcing your presence. She isn’t good with brakes, but can stop us with her bark when she needs to.

Dante

Dante is our show dog. He is our most photogenic dog, and prefers not to participate in automotive repairs for fear of getting his fur dirty. Although in summer, he loves to feel the cold air after we do an A/C job.

Miranda

Miranda

Miranda is the youngest of the dogs, we took her on as a diagnostic tech. Turns out dogs don’t see color well, and a lot of wiring is color coded, so now she just hangs out and applies her cuteness in the office.
