Its true what everybody else says, the vets are used to it.
I help out at the vets and people often say "she/he's a nightmare to handle", however it must be the shock of the journey but they are usually as good as gold, but we know they are probably a handful at home. My vets now believe mewhen I say somebody is a problem. In fact they sedated Sorrell on the floor because I told them she was a jumper, the vet nurses were less sure until I told them Kizzy would bite and she got the nurse- they listen now too.
So don't worry, and if you'd rather handle her than a nurse, say so.
