Mmm, well as long as she goes back to normal once she is home I guess it is ok
My girls do the same thing when we go over my in-laws and get together with their beagle, I have to put them apart sometimes cause they get all dirty and crazy playing with that dog, they also start barking loud, bitting, turning upside down the food and water bowl and other behaviors that are usual on that dog, while they are very well behaved at home. I let them go wild for a while, after all they seem to have so much fun
but once we re back home they just go back to normal..thank god
