Ouch

I don't know if it'll show up on your monitor, but look to the left of the Lucy's chest. That's where the vet took her blood. He took her blood on a Saturday; I took this photo on the following Thursday. Check that bruise! The poor little thing! Now, I remember when I went to the dentist he used a teeny-tiny needle to shoot some deadener in my gums. I never even felt the needle.
So, couldn't the same sized needle be used on a small dog? No! He used a gigantic human sized needle.
