Hi my senior dog was just diagnosed of having pyometra, I don’t know if its closed or open type , but a lot of brown discharge is comming out of her vagina, the vet asked for an expensive price that we looked right away for other vets, we found one that is cheaper, she will undergo surgery tomorrow morning, I’m concered about the dextrose in her front leg, is it alright to iv her before surgery or should I take it off for her to be ready ?
