I think it was when Harley was getting his last lot of puppy shots he flinched as the needle went in and it came out the other side. Poor little monkey!
I use to always get embarrassed trying to take both of mine to the vet at the same time, I would have one wanting to go one way... the other in the other direction. I would go dressed for work and would have to change again. I don't take them together any more
