Thank you for your replies. Those are the types of things I am concerned about with the injection, and although I would love to be able to take up the opportunity to work her at Crufts (she is the first dog I ever qualified, and it is probably the only chance I will get to take her there) it does not mean so much to me that I will put her health at risk or reduce the chances of having the possibility to breed from her one day.
Thank you,
