I can sympathize with your poor baby. I got stung by a wasp on my finger about a month ago and it hurt so bad. Stupid me, it was in the house and I spotted it on the floor so I had stepped on it and thought I killed it so I picked it up with a paper napkin and it stung me through the napkin.
I have never had a sting hurt that much. I can only imagine how much it would hurt a little yorkie. I pray she will continue to get better.
