one is to work the syringe back a forth a little to make sure it isn't stuck (so you don't suddenly shoot too much), and also instead of opening her mouth, try to sneak it in between the teeth on the side of the mouth. sometimes a finger pulling the lips back on the side will make her open a little. but it's a trick for sure, to do by yourself. can you get a neighbor to help you???? I had to call my neighbor over a few times. then I found some ways to sneak up when she was sleeping the right position, block her backward exit , and get it done.

good luck. so glad she is better. I used to have steps for my old dog to get on the bed. being by you is probably her best medicine.
