I have to give my girl medicine by mouth, and she's not making it easy at all. It took me and my boyfriend to even get her mostly still, and I barely got the syringe in her mouth. Any tips or tricks to getting a good hold on her without hurting her? I'm afraid to put too much pressure in case I hurt her neck, but without enough she just slips right through my fingers. I don't want it to be a fight the next two times I have to do this, and the longer we struggle with her the more stressed she gets.
