If possible I would take her to vet just for visits.

Walk her in feed her some treats. Walk her out.

Next time walk her in weigh her (if they have a scale out front) give some treats, leave.

Walk in let the receptionist or a vet tech love on her, give her some treats leave.

Hopefully if you can do this it will desensitize her to going there. She will start to look at it as a place to get some extra special treats and love.

Good luck.
