I bring my dog to the shop most of my shifts in the summer. Here are some positive and negative things that happened:
meet them, and then gives the people around them something else to talk about.
We had also had cases of:
that volunteer came, then they insisted i bring the dog anyways and took antihistamines)
the shop, and sat with her when they wanted to get closer)
not come into the shop until she had been leashed in the back area.
Honestly, having her in the shop is awesome, and the few negative scenarios were individual events that were dealt with as needed.
I would advise you to have the people who would be on that shift meet the dog, and talk about their individual concerns, and then just do it. Waivers are an awful way to instill confidence.
