You'll be fine and Guiness will do great too! We just got home from the vet. KaCee got her rabies shot this morning. Just some friendly advice though...don't let Guiness see the needle. The first time she got a shot, KaCee watched the vet stick her. She welped for probably 5 minutes afterward. The second time, she saw him take the needle out of the drawer and she freaked out before it was even near her.
Good news though! This time, she was preoccupied playing with the tech and the vet gave her the shot before she even saw it coming. And guess what?! Not a peep out of her!!
I'm sure Guiness will do just fine. Keep us updated!
